Anthropology Quote of the Week:

"Physical variations in any given trait tend to occur gradually rather than abruptly over geographic areas. And because physical traits are inherited independently of one another, knowing the range of one trait does not predict the presence of others. For example, skin color varies largely from light in the temperate areas in the north to dark in the tropical areas in the south; its intensity is not related to nose shape or hair texture. Dark skin may be associated with frizzy or kinky hair or curly or wavy or straight hair, all of which are found among different indigenous peoples in tropical regions. These facts render any attempt to establish lines of division among biological populations both arbitrary and subjective." - AAA website, February 2016

Take notes during the video and answer these questions while you watch. You may need to rewatch the video several times. Also, refer back to Chapter 2, if necessary, to fully understand DNA.

1. What are mitochondria and the Y-chromosome, where are they found, and how can they be used to understand human origins?

2. What are "haplogroups" and where is the vast majority of haplogroup diversity found?

3. What is the "Out of Africa" hypothesis?

4. What is the "molecular clock" and what does it tell us about human migration?

5. What does the Y-chromosome reveal about migration patterns of men?

6. What are two hypotheses that explain why the mtDNA and Y-chromosome evidence stops about 200,000 - 300,000 years ago?

SUBMIT: E-mail your answers (not an attachment)
to:, with the SUBJECT: ANTH5

Due by Friday, Feb 22, 5pm

(Note: for regular correspondence, do not use the above link to email me, or remove the automatic subject line heading "ANTH#" if you do).

Note: I will give you 3 chances to get the subject heading correct and to not include attachments in your online media emails to me.

For example, when you sent the first online media assignment, you should have used a subject heading in the email of "ANTH1." If you wrote something else (like, for instance, "Online Media Questions 1" or "anth 1 hw"), or if you have included your assignment as an attachment, you have not paid attention to the details of the assignment instructions (details which make it crucially easier for me to organize your responses and read what you have written).

You can do this three times without penalty, but a fourth and further instances of not paying attention to the details will result in a 1-point reduction from your Online Media grade. For the vast majority of you who are doing it right, thank you for paying attention to the details!

- Regards, Prof Reymers

The online media assignments:

Each week, excepting exam weeks (see the course schedule) you will be reponsible for completing and submitting by email a weekly online media activity. This may entail doing a reading or watching a video made available online, or performing some other kind of activity. Instructions will be posted weekly right here on the webpage by Monday and will be due (by email) on Friday at 5pm of each week. You should e-mail your completed assignment to, with the a subject heading of "ANTH#" (with "#" being the number of that week's online activity, as noted above).

Note: for regular correspondence, do not use the above link to my email, or remove the automatic subject line heading, as activities with this subject line are automatically filtered into my email activities folder (and thus I will not see an email having to do with something else until the following week or later).
