Fossil record- species evolve differently in different environments . different species evolve similarly in the same type of environment
homologous structures of living organisms- 2 variations; similar body structures that don't necessarily have similar functions
homologous- diff mature forms but develop from embryonic tissues
vestigial- similar structures with reduced size and lesser or no functions
embryology- early stages of many animals are very similar- suggesting that organisms share common ancestry
The feature that helps organisms survive better in its environment is adaptations.
