Question

Some beetles and flies have antler-like structures on their heads, much like male deer. The existence of antlers in beetle, fly, and deer species with strong male-male competition is an example of ________.A) homology B) similarity due to shared ancestry C) parsimony D) convergent evolution

Answer 1

Answer:

The correct answer is D) Convergent evolution.

Explanation:

Even though between flies and beetles it could be considered as a homology, between such insects and deers it's absolutely a convergence. Homologies are comparable characters between taxons that could have evolved from a common ancestor that had these structures. The common ancestor between insects and deers is really far in the phylogeny so the structure is not comparable.

Answer 2

The existence of antlers in beetle, fly, and deer species with strong male-male competition is an example of convergent evolution.

What is convergent evolution?

Convergent evolution is the evolution of the same features in different species or totally different species.

This evolution creates analogous structures that are not present in the previous common ancestor.

It is also called parallel evolution, in which two species evolve the same characters independently.

Thus, the correct option is D) convergent evolution.
