Evidence of Evolution Practice Quiz
The number and location of bones of many fossils vertebrates are similar to those in living vertebrates. This is evidence of what? Tendency towards perfect organisms. Common Descent Analogous structures Acquired Traits
Answer: Common Descent - They came from the same ancestors this is an example of homologous structures.
