This Year's (2024) Textbook-free Human Origins and Evolution

I’m still teaching APG 201 Human Origins and Evolution to an auditorium of 120 students every Fall semester. Unlike what students do at other universities, there is no weekly small-group lab for a fourth credit because we do not have graduate students to teach those.  

And, I’m still teaching the course without a textbook, but there are readings galore (one from a textbook!) and they can always use this free textbook as a resource if they’d like: https://explorations.americananthro.org/index.php/pdf-chapters/. 

In case it helps anyone, I'm sharing a bit about the course and all but the very last prompt (aka assignments) they have to address in their Book of Origins (moleskine) in preparation for each class. There are 37. If you’d like to try something like this, let me know and I’ll share my detailed instructions for students regarding the Book of Origins. I’ve seen it all go sideways every which way possible, so the instructions are now bullet-proof.  The one thing I'll make clear here is that students have to fill at least one page to complete each assignment and they may do so by writing or drawing, but if they draw they must write an explanation for their drawing (as in, they must write enough to make it clear why the drawing is there on the page.)

APG 201 Human Origins and Evolution

Description

This is a course about how you evolved. This is your natural history. To write it, we will learn from biological and evolutionary anthropologists who study human and nonhuman primate biology, behavior, diversity, adaptation, and evolution to better understand the human species and explain how we arrived at our current condition: Incessantly chattering, tailless, furless, culturally dependent, big-brained, bipedal creatures who are diverse in appearance and culture and inhabit nearly all types of habitats on Earth. Along our journey we will ask ourselves how we know what we know. We will also address, head-on why so much of this material is culturally controversial. The science of human evolution and its dissemination into the popular imagination has a long history of racism and sexism. In this course we will address that history by identifying outdated and mistaken evolutionary thinking. A long tradition of making Homo sapiens the hero of human origins and evolution is one major cause of this problem, which is why we take a biographical approach to our natural history, running through the human lifespan, instead of marching progressively up through the sandstones of time towards a destined triumph (as the story often, unscientifically, goes). Here, we take back our evolutionary history, scrubbing the story from the facts and evidence, making it fit for all humankind. And, who knows? Maybe we’ll find that the truth is lovelier than fiction.

Required Materials

1. Moleskine* Classic Collection, hardcover book, any color, 5 x 8 1/4 inch (these page dimensions are required) and must have at least 96 pages (though the ones with 240 pages seem easiest to purchase), ruled/dotted/unruled/ etc is your choice. You will be writing and drawing in this book so lined or dotted pages are recommended over completely blank ones. *You may purchase a different brand other than Moleskine, but the page size is required and so is a book-ish spine (not a spiral wire).

2.   A Most Interesting Problem: What Darwin’s Descent of Man Got Right and Wrong about Human Evolution by (editor) Jeremy DeSilva. Buy/rent/borrow this anywhere you wish. Feel free to read the digital, Kindle, or audio versions. I put a copy of this book on reserve at the library.

ASSESSMENT

Exam 1                                              15%

Exam 2                                              15%

Book of Origins                               50% (due on the last day of class and graded once, then)

Final Exam                                       20%

Total                                                  100%

Exams take place in the classroom and will consist of true-false, multiple choice, and questions that ask for short written answers, maybe fill-in-the blank, maybe a paragraph or two. Practice questions will emerge in class throughout the semester. The first exam is on the material since the start of the course. The second exam is based on the material since the first exam. The final exam is cumulative, so based on the entire course, but you will be able to use your Book of Origins for reference during the Final Exam.

 Book of Origins

Prompt 1. Consider these questions and (without fear) write your responses in your notebook or directly into your Book of Origins. Address all 10 questions. Who’s your audience? You right now and your future self.  

 1.      What is evolution? (i.e. What do you know about evolution as of today?)

 2.      What do you know about human evolution as of today?

 3.      What are you interested in learning about human evolution?

4.      Is human evolution, in general, something positive, negative, or neutral to you? 

 5.      If someone asked you to tell them the story of human evolution, what story would you tell them?

 6.      Do you consider human evolution to literally be a “story”? Why or why not?

 7.      Past students in this course have said that “evolution is racist” and that “evolution is sexist.” What do you think they were talking about? How do we fix this?

 8.      Make a note to your future self that explains that whatever future-you is about to read in this book could be riddled with misunderstandings and errors or that it may contain perspectives and opinions that have changed since you wrote them. Explain to your future self why it may contain those things.

 9.      Draw yourself, a part of yourself, or a symbol or symbols that represent yourself.

10.   And, finally, on the next page jot down something separate from all of the above (but it can be related/redundant, that’s fine): What’s one thing you’re taking away from class today that matters to you? And see if you can explain (as brief as you’d like) why it matters to you.

 

Prompt 2. The Scientific Process!  To do this assignment, you must choose one of the well-known and established observations listed below (A, B, or C):

A) In most humans, the right humerus (upper arm bone) is larger than the left one.

B) Chimpanzees living in zoos tend to weigh more than their relatives living in the wild.

C) Among infant chimps, females ride on their mothers for longer than males, who start walking independently more frequently at a younger age than females.

Next, without using anything but your own mind…

1.      If you had to choose one of those observations to study (try to explain) in real life, which would it be and why? 

2.      Represent that observation with an illustration or a graphic (i.e. what’s called a “figure” in a scientific paper) as if you had data (which you do not, so numbers are unnecessary, or you may make some up).

3.      How would you verify the observation? Offer up a way to verify it. That is, describe the steps you would take to establish that it is a correct observation (and lend credence to its factuality). In other words, how would you go about making this observation for yourself, seeing it for yourself? While scientists and scholars look to the scientific literature (articles and books) or to published datasets, those are not options for your answer today. What would you do "in the field" (either with human skeletons or with live chimpanzees) to see for yourself (a.k.a. verify) either a, b or c?

4.      Now, go ahead and accept your observation (a,b,or c) as fact (because it is) and explain that one observation. Come up with at least two hypotheses/explanations for that observation. This is brainstorming, and is part of the scientific process.  Again, like with #1, do not google around; use nothing but your own mind if at all possible. Have no fear. This is a playground!

a.      Need a refresher or a foundation on the scientific process and what “hypotheses” are? Go to here: https://undsci.berkeley.edu/article/howscienceworks_01 (pages 1-21 are awesome).

5.      Briefly describe how you would test at least one of these hypotheses/explanations for a, b, or c.  Include discussion of the methods and variables/types of data, and the kinds of evidence that you would need to find to both refute and to support each hypothesis.

6.      What might be some limitations and obstacles to explaining the observation?

7.      What is the value in studying this?

 

Prompt 3. Read the Preface (by Jeremy DeSilva) and Introduction (by Janet Browne) in A Most Interesting Problem, then write and/or draw what you found to be meaningful, significant, or noteworthy in the readings. If struggling to identify that information, then pull out what you have questions about, what you’d like to learn more about, what you’re uncertain about, what surprised you, what relates to other material we have already covered in the course, or what may relate to what you anticipate we will cover down the road. (Remember to title the page or do something to make this page make sense to future you.)

Prompt 4. Know Your Apes:  For all seven of these critters--gibbons, siamangs, orangutans, gorillas, bonobos, chimpanzees, and humans--use at least one page per ape to answer the following questions. Complete sentences are not necessary, as long as the info is there. Get your information from  these excellent websites listed below (and more information will come in class, soon). The only snafu you may encounter is researching humans and if that's the case, just do your best with what you know about humans, as a human.

Prompt 5. Based on lecture/discussion/handout, answer the following questions. (Remember to either include the question or answer in a way that the reader understands without knowing the question.):

·        What's the relevance of Linnaeus to our course?

·        What's an example of a homologous trait among vertebrates, link it to your body.

·        Why are you a primate?

·        Which nonhuman ape is the best ape? (Make a case for one ape being the best ape.) Suggest a possible reason why your professor asked you this question.

Prompt 6. Read Chapter 1 by Alice Roberts in A Most Interesting Problem, then write and/or draw what you found to be meaningful, significant, or noteworthy in the readings. If struggling to identify that information, then pull out what you have questions about, what you’d like to learn more about, what you’re uncertain about, what surprised you, what relates to other material we have already covered in the course, or what may relate to what you anticipate we will cover down the road.

In addition to course materials, especially Hailie-Selassie’s chapter in A Most Interesting Problem, you may want to look to the Smithsonian’s Human Origins page: https://humanorigins.si.edu/evidence/human-fossils. Google is fine too, but beware! That Google brings the Smithsonian up for me, first (or nearly first), for all those hominins up there warms my heart. Wikipedia is fine too. But be sure to check your book and the Smithsonian first.

This response is complete as long as there are seven pages, but you do not literally need to fill the page with facts. You can fill each page with an image and include very few meaningful facts, if you wish.

The more facts the merrier, though! And as you make your pages, ask yourself... Why do these individuals and species matter? What is interesting? What do we know? What don’t we know? How do they relate to you? How do you relate to them? 

[Aside from the very last prompt, all the responses from now on are only 1 page. Whew!]

Prompt 10. Watch Lice and Human Evolution (PBS NOVA, 10 min) https://www.pbs.org/wgbh/nova/video/lice-and-human-evolution/ .  Write and/or draw what you found to be meaningful, significant, or noteworthy in the readings. If struggling to identify that information, then pull out what you have questions about, what you’d like to learn more about, what you’re uncertain about, what surprised you, what relates to other material we have already covered in the course, or what may relate to what you anticipate we will cover down the road. 

Prompt 11. Monkeys all the way down? This is a two-part prompt.

a.      Read “Monkeys all the way down” by Dunsworth (https://www.sapiens.org/column/origins/monkeys-all-the-way-down/ ) then answer this question: Did we evolve from monkeys and apes? Explain.

b.      Calmly and kindly respond to a hypothetical, but agitated friend or family member who says, “If we evolved from apes, then why are there still apes?” Write and/or draw your response to them in one page, minimum. And don’t forget to title it so that future you knows what’s happening on this page.

Prompt 12. Are we apes? Provide both a yes and no answer with reasoning to back each.  While doing so, reveal whether you side with yes, no, or neither, and explain why that is. Here are some entertaining resources that may help you form either or both of your answers. If we have time, we will discuss this question in class.

·        The side of no, we aren't:

o   You Are Not an Ape! Jon Marks at TEDxEast (17 mins): https://www.youtube.com/watch?v=fLfdKk9JEp8

·        The side of yes, we are apes:

o   Wrongheaded anthropologist claims that humans aren’t apes: https://whyevolutionistrue.com/2015/11/02/wrongheaded-anthropologist-claims-that-humans-arent-apes/

 

Prompt 13.  Scenario-building or storytelling?

Without looking anything up (except to find and observe pictures of the primates or to look up terminology, like in that open access/free textbook I posted on Brightspace, or in the online Merriam Webster dictionary, etc etc), write an answer for each of the questions below. It is crucial that you DO NOT GOOGLE THESE QUESTIONS or type them into AI chat thingies or anything at all. I forbid you from asking anyone or any algorithm the questions, below, because thinking them through is the point of the exercise. Exercise your freedom to think and imagine based on where you are now. To complete this response you need to provide 5 answers, one for each question below. It's totally possible to do all five answers in total within that one page minimum. If you're not feeling brief, then, as always, feel free to go over the one page minimum. Your answer to each question, below, is a hypothesis (a good guess) to explain the evolution of each of the five phenomena. These are evolutionary scenarios that you are writing. This is brainstorming only, so have no fear of being wrong, but be clear.

1. How did the mandrill (monkey) get that colorful face? What about the rear (which looks like the face)?
2. How did the black and white colobus monkey (a leaf-eater or folivore) get a long, specialized gut?
3. How did gorillas become the largest primate?
4. How did silverback gorillas become twice as big as females?
5. How did humans become “naked”? (i.e. how did we come to be less furry than the other primates)?

 

Prompt 14.  Go here and read this article by evolutionary biologist John H. Macdonald: https://udel.edu/~mcdonald/mythintro.html

When you get to the part that says “Summary for worried parents” read through those points and choose at least one to dig into more deeply by clicking on the trait and learning more.  Write up and/or draw what you learned, what it means to you, and what you’re left wondering.

For each of those human traits (in that list of bullet-points in the article), there is a myth that one form is recessive. (It’s based in the larger myth that all genes have a dominant and a recessive allele.) If that were true, then two parents with the recessive trait could not have a child with the dominant trait. And, if that were the case, then it would be possible to look at these traits in a person and know something about their biological paternity. We cannot.

 

Prompt 15. Read “Things Genes Can’t Do” by Weiss and Buchanan (Aeon)
https://aeon.co/essays/dna-is-the-ruling-metaphor-of-our-age 

Then, just like with the readings you’ve already done, write and/or draw what you found to be meaningful, significant, or noteworthy in the readings. If struggling to identify that information, then pull out what you have questions about, what you’d like to learn more about, what you’re uncertain about, what surprised you, what relates to other material we have already covered in the course, or what may relate to what you anticipate we will cover down the road. (Remember to title the page or do something to make this page make sense to future you.) But, also, be sure to highlight (by writing about it) what you believe is the most important point that Weiss and Buchanan make and explain it. 

 

For any readings below that lack specific questions for you to answer, this is the prompt: Write and/or draw what you found to be meaningful, significant, or noteworthy in the readings. If struggling to identify that information, then pull out what you have questions about, what you’d like to learn more about, what you’re uncertain about, what surprised you, what relates to other material we have already covered in the course, or what may relate to what you anticipate we will cover down the road. (Remember to title the page or do something to make this page make sense to future you.)

Prompt 16. Read “Where did they all go? How Homo sapiens became the last human species left” in The Guardian

https://www.theguardian.com/science/2023/nov/18/where-did-other-human-species-go-vanished-ancestors-homo-sapiens-neanderthals-denisovans


Prompt 17. What are some important things you have learned so far in the course (whether in the classroom or in responding to prompts)? Be sure to explain why they are important, in the world or to you, personally.


Prompt 18. Read “Social and Biopolitical Dimensions of Evolutionary Thinking” by Jonathan Marks and Adam Johnson

https://pressbooks.calstate.edu/explorationsbioanth2/chapter/17/

 

Prompt 19. Read “The Coronavirus is Mutating” (Washington Post) (posted on Brightspace).

·        Note/quote the parts of the text that refer to genetic drift (even though it is a term which is never uttered in the article).

·        Note/quote the parts of the text that refer to natural selection (whether it says the term or not).

·        Next, there is a preference (or something like it), in this article, for natural selection-based explanations? If so, then why do you think so? If not, then why do you think that Prof. Dunsworth asked about it?

 

Prompt 20. The future loss of wisdom teeth in our species? For this assignment, read this long preamble, and then the short news article pasted there, and then answer questions A, B, and C.

Remember…

• Most of us were taught incorrectly or led, wrongly, to believe that 'evolution' = 'natural selection' which implies that all evolution occurs through natural selection. This leads us to see every evolutionary scenario, all the way from fairy tale ones to the most scientifically legitimate ones, as natural selection. This is, of course, not a correct understanding of evolution.

• Natural selection can result in new adaptations or in the elimination of bad traits. The former is "positive" selection, the latter is "negative" and is always occurring no matter what. Positive selection does happen but is not easy to test, since natural selection occurs via differential reproductive success, but "survival of the lucky" alleles via genetic drift can look exactly the same by increasing and decreasing allele frequencies just by chance. The difference between the two (natural selection and genetic drift) is that, in a selection scenario, the trait that's evolving is causing the differential reproduction (whether enhancing or inhibiting, even if ever so slightly affecting it slowly over time), but in a drift scenario the trait is "drifting" (like on the surface of the ocean) to lower or higher frequencies over the generations merely due to chance (unlinked to the trait in question) effects on differential reproduction and due to chance passing of one allele or the other to offspring. Like selection, drift can completely fix or completely eliminate traits! Genetic drift is always occurring, and so is negative selection to some degree (the disappearance of mutations that prevent survival and reproduction, which is to say their own existence) and positive selection to some degree (the rise in prevalence of mutations, new or old, that enhance survival and reproduction, which is to say that they contribute to their own existence).

Read this short news story:

Wisdom teeth might be lost as people continue to evolve: Why the modern diet may make wisdom teeth unnecessary About 25 to 35 per cent of people will never get their wisdom teeth by Astrid Lange Toronto Star Library, Jun 25 2013

Wisdom teeth are the third and final set of molars that most people get in their late teens or early 20s. But not everyone does — the American Dental Association estimates that about 25 to 35 per cent of people will never get their wisdom teeth. Another 30 per cent will only get 1 to 3 of them. Anthropologists believe wisdom teeth evolved due to our ancestors' diet of coarse, rough food — leaves, roots, nuts and meat — which required more chewing power and resulted in excessive wear of the teeth. Since people are no longer ripping apart meat with their teeth and the modern diet is made of softer foods, wisdom teeth have become less useful. In fact, some experts believe we are on an evolutionary track to losing them altogether.

Now, respond to A, B, and C. 

A.     Briefly explain the evolutionary mechanism behind the evolutionary scenario for future wisdom tooth loss that the author of the news article above alludes to. In other words, think about what the writer is really hypothesizing for future human evolution and rephrase their explanation, but scientifically, in terms of all or just some of the four main mechanisms of evolution that we discussed in class which are mutation, gene flow, genetic drift, and selection. Important! Banned words for your scenario include: Need(s/ed/ing), want(s/ed/ing), try(s/ed/ing), best, most and fittest.

 

B.     Write out an alternative scenario where selection is responsible for the loss of wisdom teeth in our future selves. If it's not obvious, this will be a significantly different scenario from what the writer has imagined in the news article and from what you wrote in response to 'a.' Important! Banned words for your scenario include: Need(s/ed/ing), want(s/ed/ing), try(s/ed/ing), best, most, and fittest.

 

C. Having 0-3 (instead of all 4) wisdom teeth develop is a fairly common phenotype out there just like the previous article said, and it probably includes people in APG 201.There's a story out there in science and in pop culture that, because we evolved to have smaller jaws in the last six million years of hominin evolution, natural selection is currently favoring people who don't form wisdom teeth at all. That is, people think that there are people who don't develop all four wisdom teeth because it's adaptive not to, because our jaws are so small and it's a health risk to fit all those teeth in a small jaw. They explain this pattern of human variation with natural selection (the way we legitimately do with skin pigmentation variation) and it helps justify third molar extraction. Now, knowing (1) that there's all kinds of dental variation in humans, deviating from what's typical, in terms of which teeth they do or do not develop and that's also true for apes who have large, roomy jaws, and live in the wild, and (2) a bit (from skimming) the mind-blowing information in this brief article "The Prophylactic Extraction of Third Molars: A Public Health Hazard" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1963310/ .... WHAT'S YOUR TAKE on that just-so story about humans who naturally don't develop wisdom teeth because it is adaptive no to? As far as evolutionary scenarios go, is that story good, bad, neutral, or otherwise? And, does that evolutionary thinking justify us getting our wisdom teeth routinely, prophylactically removed?


Prompt 21. Deciphering and polishing your evolutionary scenarios. Look back at the answers to the following that you wrote in an earlier prompt several days ago….
1. How did the mandrill get that colorful face? What about the rear (which looks like the face)?
2. How did the colobus monkey (a leaf-eater or folivore) get a long, specialized gut?
3. How did gorillas become the largest primate?
4. How did silverback gorillas become twice as big as females?
5. How did humans become “naked”? (i.e. how did we come to be less furry than the other primates)?

For each of those evolutionary scenarios that you wrote in an earlier response/chapter in your book, label (consider using a different color ink than what you used to write, originally) which evolutionary mechanisms (mutation, drift, selection, gene flow)) that you hypothesized were at work in each of your scenarios. Back then, you probably didn’t use all the terms and ideas we covered in class more recently, but you may have been getting at some of them in other words.


Next, on this page for this response, rewrite a scientifically improved version of each of the four explanations you wrote earlier.  Make them more scientifically accurate by using the four main mechanisms of evolution and using their terms as you write: mutation, gene flow, genetic drift, and natural selection. You may need to just change a few words or you may need to completely revise the entire answer, it depends on what you originally wrote. Brief can be excellent!  Important! Banned words include: Need(s/ed/ing), want(s/ed/ing), try(s/ed/ing), best, most, and fittest.

Prompt 34. The True Story of Ota Benga. Read and/or listen to the following: From the Belgian Congo to the Bronx Zoo (NPR): http://www.npr.org/templates/story/story.php?storyId=5787947, then react meaningfully and make sure to address the following: What is a link between racism and evolutionary theory and what do you think about it?

Not required: These are two highly recommended literary contributions to what we're grappling with, which is why I posted pdfs of each on Brightspace.

1.      [Note! This is a fictional account based on the real history.] A True and Faithful Account of Mr. Ota Benga the Pygmy, Written by M. Berman, Zookeeper – Mansbach http://adammansbach.com/other/otabenga.html

2.      [Note! This is very dark sarcasm and not to be taken literally.] How to Write About Africa – Wainaina (Granta): https://granta.com/how-to-write-about-africa/

 Prompt 35. Ancestry is not race is not human biological variation is not race is not ancestry. Distinguish all three of those phenomena in humans (ancestry, race, and human biological variation) from one another. For "race" you must stick to humans. Whatever people call a "race" in other organisms is not race in humans. Be sure to consider why is it important, or why it matters that we make these distinctions between these three concepts. You must find a quote to use in your answer from Ch. 7 by Fuentes in A Most Interesting Problem) and you must quote or cite at least 1 other resource from the list below in your answer. If any link leads you to a paywall, don’t pay a dime; there’s a good chance you can get past the paywall through the URI library. (If you need assistance using the library to find any of these, I’m available to help! Or choose another article that’s not subscription based!)

Prompt 36. Sex, Gender, and Human Evolution. Taking into account anything from this course, and your life, answer these two prompts citing at least one source for each (still, one page is all you need): (1) Sex is not gender and gender is not sex: what does that mean? (2) Contemplate how and/or why old/bad science encouraged people to deem women "inferior.”

[Prompt 37 is not yet written for this year. It will be a lot like previous years. It will include a letter-to-day-one-self as well as a self-grade, but there are always a few more specific questions about evolution here as well (but no reading, etc).]
