Question

List and briefly describe each of the 4 types of evidence that support the theory of evolution.

Answer 1

The answers are:

1) Fossil record - Comparing fossils from older and younger rock layers.

2) Geographic distribution of living species -Species evolve differently in different environments. Different species evolve similarly in the same type of environment.

3) Embryology - Early stages of many animals are very similar- suggesting that organisms share common ancestry.

4) Homologous structures of living organisms - 2 variations; similar body structures that don't necessarily have similar functions.

Answer 2

The fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.
