BIOLOGY
·
· 1. Geneticists compare DNA base sequences among organisms and from this data determine a gene’s rate of evolution. Different genes have been found to evolve at different rates.
·
o
– Explain why some genes might have faster rates of evolution than other genes as populations adapt to their environments, and give an example with your explanation.
·
· 2.Species have been traditionally characterized as “primitive” and “advanced.” For example, mosses were considered to be primitive, and flowering plants advanced; crocodiles were primitive and mammals were advanced. Most biologists of today think it is incorrect to characterize any modern species as primitive.
·
o Determine whether or not you believe it is incorrect to refer to any modern species as primitive, and explain why.
