What evidence supports the hypothesis that whales evolved from land-dwlling mammals?
Theory of evolution
What are 2 types of structural evidence?
Evidence that tells that, through the structures of two organisms, can be compared that we have a common ancestor and have evolved from them.
What evidence supports the idea that life could have evolved on europa?
Evidence to support the idea that life could have evolved on Europa includes the presence of a subsurface ocean with conditions potentially suitable for life, such as the presence of water, organic molecules, and a source of energy from hydrothermal vents. Additionally, observations of plumes of water vapor and evidence of past geological activity suggest that Europa could have the necessary ingredients for life to have evolved.

What feature of agnathans evolved into jaws in early jawed fishes?

How does Archaeopteryx provide evidence for evolution?
Archaeopteryx lithographica is a specimen of early bird that still shows many traits characteristic of theropod dinosaurs. As such, they are a morphological intermediate between theropods and modern birds, confirming the hypothesis that birds evolved from dinosaurs.
