Mitch Bach -- May 22 -- 3/3

What we did:

-finished Hardy-Weinberg notes on PowerPoint and sheet.
-worked more on Hardy-Weinberg calculations.
-learned and got Changes is Gene Pools (21.2) notes.
-learned about evolution and how it comes about.
-assigned worksheet, p. 730 #11b, p. 734 # 1,3,4,5, & 7.

Thoughts and Opinions:

Today's class was interesting in the fact that were using easy math to calculate what big changes in gene pools can cause. Once you get a hold of the math it comes easy with every question thrown your way. Evolution was interesting because all organisms have gone through some sort of evolution at some piont of time.

Above and Beyond:

Learning about evolution got me thinking that humans would have gone through evolution as well. I wondered what we could have looked like.... http://www.pbs.org/wgbh/evolution/humans/humankind/index.html shows a step by step introduction of how evolution of humans progressed. It says that humans first became distinguished from apes 8 million years ago!!!! Its tough to tell what we first looked like, but it must have been some kind of cross between apes and what we are now. The earliest history of our ancestors can only be traced back through fossil, making it really difficult to decipher what we actually looked like.

  1. nice work. Some of us still look a bit more ape-like than others!
