Document Summary
This often happens in the same geographic area. Directly observed evolution structures in related species: a vestigial trait is a structure that has no function, but is similar to functioning, examples, fig. 24. 5: although much evolution occurs very slowly, some kinds of evolution can be, and have. 468 470: if species evolved from a common ancestor, we expect to see evidence that they are been, observed on faster time scales. 24. 6: in nature we observe many, often surprising, similarities between organisms. Almost identical developmental genes in fruit flies and people. Similar limb bone structure in turtles and people. Similarities apparently due to homology are widespread. Homology: the theory of evolution explains these similarities as homologies, a homology is a similarity that is due to common ancestry, genetic homology is homology at the level of genetic coding, examples: theory of evolution. The genetic code itself is shared (with rare, minor exceptions) by all living organisms.
