In this part of the course we will work towards understanding the evolution of our species while also squeezing in Chapter 13 . Chapter 13 is about how species form and how we define species. This information will be useful as we work to understand our very own species and our evolutionary history. We will wrap up the semester by reading parts of the book “How to argue with a racist.”
What makes difference and what difference does difference make?

Week of May 12th (Poster Presentations in Lab-these should only last half the lab period.)
- MON- Read carefully HarvardBlogVivienChou (I left this link in to make a point!). Here is the version I downloaded last year and saved on my laptop – ChouV 2017 Harvard Blog How Science and Genetics are Reshaping the Race Debate. Also read this AAPA_Race_statement_March_2019 and https://www.bbc.com/news/science-environment-51914782

Final Exam is…Saturday May 17 9-11am
Office Hours: Thursday 12:30-1:30, Friday 10:30-11:30 and 1-2, I am available other times too earlier in the week-email me!
- Add any questions you might have to this ppt!
- Final Exam Review25
- Gram Staining and Protist Pictures are some awesome Gram Staining and Protist images from lab!
- GalleryWalkImagesScored are the Images we had up in class that you then ranked in a google form for Humans are “Same” or “Different.” Its really interesting to see the patterns!
- A couple folks asked for the MEGA Handout so here it is…there are a couple questions you were supposed to be answering as you went along. FYI: Aligning is hard to explain so I would not ask you about that as and bootstrapping is even harder to explain so I would not ask you about that either!Using MEGA to Build Phylogenies
A couple of the handouts from class and “Keys” for some but not all…
- Part I. Skin in the Game Q Key
- Part II. Sorry no key for the second handout but here is the handout! Part 2 Your Ancestors are My Ancestors (Why do you think I asked you to put numbers to your different great grandparents? How meaningful is it to focus on a single great, great grandparent while ignoring all the other genomes in your family tree?)
- Sickle Cell Disease+HypertensionTableKEY
Ppts are here …
Other resources…Actually some of these I assigned but some I did not. All review useful concepts!
- This is a great video (8 minutes long) that talks about discoveries that the Y chromosome in Neanderthals is more similar to human Y chromosomes than their most recent common ancestor’s Y (their most recent common ancestor are Denisovans). Further indicating lots of ancient interbreeding. Talks about gene flow and ramifications of small populations!
- Love in the time of climate changeGrizPolBears (I assigned this-great 2 page article on interbreeding as climate warms)
- Whats in a name? (This is an excellent wrap up of the challenges of different species concepts applied to birds-nice pictures!)
- RedWolvesSpecies? (Also interesting)
- Watch this quick video Human Migrations with Nice Music and, if you are not sure about how we reconstruct human migrations with molecular markers, look over this MolMarkersWithColoredBlocks
- Neanderthals, Interbreeding and Recent Human Evolution- Neanderthal traits in us
- An excellent short article describing Skin Pigmentation-Vit D-Folate story (also in “Skin in the Game” Chapter of How to argue with a racist! Discover Mag Vit D Folate
- Can someone pass as a Neanderthal?
- News article about two identical sisters submitting their DNA to multiple different companies.
- Genes We Lost PBS (I had you watch this but we never discussed it. It is really interesting and will contribute to your overall understanding! Vit C and Evolution)
- Confused by the fact that you and some pretty close relatives may not share any DNA? Watch this-yay recombination! https://www.youtube.com/watch?v=RZWB_xt0chY
- Still confused with meiosis and mitosis. Amoeba sister’s videos are also usually pretty good on youtube!
- This website is good review (there are many others out there too). YourGenome.org
- Does anyone need practice reading trees? Check this one out.
