Today was a typical day in a BIO. Fun as always! Got to love 8th period Bio. =)

We reviewed what a half life was and how it plays a part in EVOLUTION.

We reviewed by doing an extra problem in our packet on page 29 problem B. =(

Next, we went over the quiz that we took on Friday on 19.1.

-We talked about the difference between mass extinction and background extinction. Coevoltion which is the process by which 2 species evolve in response to changes over time.Also,we learned adaptive radiation was when a small group evolved over a short time into several different forms (beaks) that live in different ways. This takes us back to how the finches evolutionized their beak to adapt to their envoirment.

3. Lastly, we finished it up with a lab! doing a lab is a very helpful way to understand evolution and the many topics that come with it!

-We measured the head and the width of the jaw to see how are brain, head and teeth evolutionized from big jaw to a round one!
