What evidence do similarities between fossil bones and modern organisms provide?
homologous structures are evidence that the two species are related or shared a common ancestor

What would indicate that a series of fossils represent evolution?
the fossils show similarities
300
Evolved from the same ancestor, but have different functions
Homologous structures
300
What do analogous structures suggest?
Organisms independently evolved similar solutions to adapt to environmental challenges
300
Evolved from different ancestors, but due to living in similar environments have a similar function.
Analogous structures
300
An anatomical feature that no longer seems to have a purpose in the current form of an organism
Vestigial structure

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 evolved from animals that once lived on land
