In 2-3 sentences, what was the overall purpose of the lab for this week?

 

We learned about how humans share same structures as certain animals. As well as how evolution is a huge part of how humans became what they are. 

Comment:Hi Jackie, 
It looks like you have summarized the overall purpose of the week 2 lab objective succinctly. It is interesting how species are related and we can see this by comparing anatomical structures and how they change over time.
