Natural Selection and Common Ancestry

Whales live in the ocean. They do not have legs, but they do have a pelvis with small leg bones attached to it. This is evidence that:

• Whales are not well adapted to ocean life.

• Whales do not have homologous structures

• Whales evolved from animals that once lived on land

• Whales evolved from some type of fish

What evidence do similarities between fossil bones and modern organisms provide?

• species that face similar environmental pressure will develop similar traits.

• homologous structures are evidence that the two species are related or shared a common ancestor

• natural selection

• adaptive structures help organisms survive in their habitat
