You are a scientist who notices great similarity between the spines of a hedgehog and the spines of a porcupine.When you study their genetics,however,you notice that the set of genes that code for hedgehog spines is a different set of genes than the set that codes for porcupine spines.You decide this must be an example of

Question

Quizplus · Accepted Answer

The fact that two different sets of genes code for similar physical features (spines) in two different species (hedgehogs and porcupines) suggests that they independently evolved this characteristic, rather than inheriting it from a common ancestor. This is an example of convergent evolution, where unrelated species evolve similar traits in response to similar environmental challenges.
