Course
description
The biocultural
evolution of humans. An investigation into humankind’s place in nature,
including a review of the living primates, human genetics and development,
evolutionary theory, and the human fossil record. Fulfills both the
General Education outcomes A1 (STEM knowledge) and C3 (Diversity and
Inclusion)
This is your
origins story. To write it, we will learn from biological and evolutionary
anthropologists, who study human and nonhuman primate biology, behavior,
diversity, adaptation and evolution in order to better understand the human
species and explain how we arrived at our current condition: Incessantly
chattering, naked, 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 and the stigma it attached to human origins by identifying
bad evolutionary thinking, misconceptions, and the misapplications of that thinking. Class time will be spent on lectures (with
robust handouts), activities, and discussions where we take back our species’
shared origins story and make it one that’s fit for all humankind.

ASSESSMENT
Book of Origins Check
During the designated week, early in the
semester, each student will meet briefly with me to show me the initial
progress they’ve made on their Book of Origins.
Quizzes 1, 2, and 3
These are take-home quizzes where students are free to consult
class resources. Quizzes will consist of multiple-choice, short answer, and
essay. They are passed out in class and submitted in class, there is no
opportunity to obtain quizzes late or submit late quizzes for any points unless
students have an excused absence as defined by the university handbook. This
way, course attendance and participation is all wrapped up in quiz scores,
which will benefit from regular attendance and participation.
Thanks, Evolution! Project –OPTIONAL EXTRA CREDIT
This is a
journey to the evolutionary origins of something for which you are grateful. It
is a hunt for high-quality, appropriate scientific/scholarly evidence in the
literature (via Google Scholar) and a short bit of science writing. By the end
of this project you will not write *the* one true correct version of an
entity’s origins; you will write a sound scientific and scholarly origins story
(for something meaningful to you). If you choose to do this assignment, you
submit it in class at which time you present your research to the class in a one-minute
(175 word max) ‘lightning talk’ without any visuals, just your spoken words. A full set of instructions, helpful
guidelines, and grading rubric will be provided separately in class. Again,
this is completely optional extra credit.
Book of Origins– Due last day of class,
in class
Your book is
your origins story. You will write this book over the course of the semester
and keep it when our course is over. Your book is not your notebook. You will
need a separate notebook for taking class notes and for organizing handouts and
worksheets; your book is something else. Your book is due on the last day of
class and will be graded and returned to you at the time of the final exam
(which is not a final exam, see below). Your book is your creation and the
content includes your assignments entered in preparation for that
day’s class meeting as well as all information that you find
meaningful and wish to enter that’s transcribed from your classroom lecture
notes, handouts, worksheets, etc. Assignments
(e.g. 1.1, 1.2, 1.3, etc…. ) that go into the notebook are listed on the
schedule and the details of each assignment are located in the long version of
this syllabus posted on Sakai. Assignments are choreographed
readings and activities that you do outside of class, timed to maximize your
engagement with the in-class course material and your mastery of it. Some will
ask you to respond to a reading with words or drawings. Others will involve
watching films or performing interactive activities on-line. Still others guide
you to perform specific exercises in preparation for in-class activities. If
the assignment asks you to write something, you must write in your own words.
If you want to include quotes in your book, please do but they are in addition
to any assignment that is to be completed in your own words. You need to
fill at least one page, at minimum, for each assignment to get full credit for
its completion. Grading is based mostly on whether you completed the
assignments thoughtfully and professionally, not whether you completed them
entirely correctly. In other words, you earn full credit for each assignment
by putting forth the effort to complete it—as long as it’s a solid effort, is
mostly accurate, and earnestly attempts to answer the questions that are
asked! I grade this way because these
assignments are often struggles that I’m asking you to face on your own ahead
of in-class discussion. Errors in the
assignments are therefore tolerated but systematic/egregious inaccuracies are
not. Your book’s overall grade will be based on completion of assignments, effort,
clarity/legibility, organization, and additional content you have added above
and beyond the bare minimum you are asked to include in each assignment. There
are more pages than there are assignments and that space is best used, rather
than left as empty space. So, the overall grade takes into consideration how
thoughtful you are in creating your book, curating materials beyond merely
entering complete assignments. Be sure to number your pages so that you can
provide a table of contents.
Racism and Sexism Project - Due at the time of the final, in class
This is a
written assignment due at the time of the final exam, and instead of an exam,
our time will be spent sharing out with small groups and the entire class. It
is a multi-part short-essay assignment that should reflect much of what you
accomplished over the semester and especially during the last weeks. If done
well, my feedback will be to urge you to share this assignment with your people
and online. Leading up to this project’s
deadline, we will use class time to prepare. A full set of instructions, helpful guidelines, and grading rubric will
be provided separately in class.
Assignments that go into your Book of Origins
(and non-required “resources” that
support/complement the material)
These
assignments, which must each fill at least one page of your book, are
due to yourself before class on the day listed on the syllabus. Using the
assigned materials, answer the questions for the assignments by writing,
drawing, sketching, collaging, pasting pics, etc in any format that works. “Assigned”
links are crucial to answering the question for that day’s assignment. Do not
even do that day’s assignment if you have not read/viewed the assigned links. “Resources”
are not assigned, but are provided as support for the assignment and/or the course
content in class. They will be especially helpful if you do not understand
something, have missed class, or wish to learn more. Dr. Dunsworth will be
helpful in all three of those circumstances too, so contact her as well.
A Tale of Your Origins and Evolution
With chapters of our course titled according to to Propp's Morphology of the
Folktale via Misia Landau's Narratives
of Human Evolution
Chapter 1: Initial Situation. Setting your story
in motion as only humans can;
anthropology; the scientific process; taxonomy; the Order Primates; observing
the natural world and determining our place in it; evolution (change over time
in lineages that share common ancestors); phylogeny; species and speciation;
fossils and fossilization
1.1
Write and/or draw at least one page of answers to the following: What is
evolution? What do you know about human evolution? What are you interested in
learning about evolution and/or human evolution? You must translate any and all
answers to these questions that you wrote on day 1 of class into your book for
1.1.
1.2 The Scientific Process! First, choose one
of the following well-known and established observations:
a)
Children
from low income homes show evidence of malnutrition.
b)
In
most humans, the right humerus (upper arm bone) is larger than the left one.
c)
Chimpanzees
living in zoos tend to be overweight compared to their relatives living in the
wild.
Next,
without using anything but your own mind, offer up two different hypotheses to
explain that one observation. Briefly describe how you would test these
hypotheses. Include discussion of the methods and variables for obtaining
evidence and the kinds of evidence that you would need to find to both refute
and to support each hypothesis.

3.3 Look back at what
you wrote for 2.3, for each of your evolutionary scenarios (i.e. your answers
to the questions1, 2, 3, and 4), describe which evolutionary mechanisms
(discussed in class) that you hypothesized were at work in each of your
scenarios. You probably didn’t use all the terms and ideas we used in class but
you may have been getting at some of them. .

the mechanisms you used, even if you didn’t write the official terms at the

3. [list
the mechanisms you used, even if you didn’t write the official terms at the
time]
4. [list
the mechanisms you used, even if you didn’t write the official terms at the

Next, rewrite each of the four explanations you wrote back in
2.4. Make them more scientifically accurate, using only the four main
mechanisms of evolution that we discussed in class and those terms: 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. Important!
Banned words for your scenarios include: Need(s/ed/ing), want(s/ed/ing),
try(s/ed/ing), best, most, and fittest.

Remember…
•
Most of us were taught incorrectly or
led, wrongly, to believe that ‘evolution’ = ‘natural selection’ and 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 luckiest”
alleles via genetic drift can look exactly the same by increasing and
decreasing allele frequencies just by chance. The difference between the two 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 genetic drift scenario the trait is
randomly “drifting” to lower or higher frequencies merely due to chance
(unlinked to the trait in question) effects on differential reproduction and
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 (filtering out mutations
that prevent survival and reproduction) and positive selection to some degree
(increasing the prevalence of mutations, new or old, that enhance survival and
reproduction).

evolution:

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, Published on Tue 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.
_____________________________________________________________________________________
A. Briefly explain the
evolutionary mechanism behind the evolutionary scenario for future wisdom tooth
loss that the author of the blurb alludes to. In other words, think about what
the writer is really hypothesizing for future human evolution and rephrase his
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 natural 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 blurb 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.
