Practice problem
In comparative anatomy, what is a homology?
A trait, such as bone structure, that evolved independently but looks the same between two species
A trait, such as a bone structure, that first evolved in a common ancestor then differentiated as different species evolved from that ancestor
A trait, such as a bone structure, that disappeared for a time in the fossil record and then reappeared
A trait, such as a bone structure, that exists today but has no evidence of existing in fossils
Type a concept, like “slope” or “photosynthesis”.
