Describe 3 pieces of evidence that supports human evolution by natural selection.

1st piece of evidence-Vestigial structures.

Vestigial structures are bones or other organs in an organism but are reduced

in size and either have no use or have a less important function than they do in other related organisms. For example the hind limbs of whales, or the appendix of humans. Even humans tail bones are vestigial structures.

2nd piece of evidence-Homologous structures. Homologous structures are structures that share a common ancestry.

3rd piece of evidence-Amino Acid sequence. The amino acid sequence which codes for an organism's protein. The prediction was first tested by analyzing the amino acid sequences of similar proteins found in several species.
