11.
The forelimbs of vertebrates, like the ones pictured here, are similar in terms of number of bones and the orientation of bones. Which best describes how comparing homologous structures provides evidence of evolution?
a)
The genes for the body plan and forelimb layout were present in a common ancestral species vertebrates share, thus passed onto all vertebrates.

Homologous structures show that different species evolve at different rates
d)
Homologous structures don’t actually provide evidence for evolution

This is purely by chance and isn't significant
b)
The extinct dinosaur and modern bird share a common ancestor
c)
All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today
d)
Dinosaurs choose to fly, and evolved into birds to escape predation and capture food
