Question

the circumstances in which two species with very different evolutionary histories develop similar physical features as a result of adapting to a similar environment is known as a(n)
homology.
homoplasy.
natural selection.
descent with modification.

Explanation:

Homology refers to similar features due to common ancestry. Natural - selection is the process by which organisms better adapted to their environment tend to survive and reproduce. Descent with modification is the concept of species evolving over time from common ancestors. Homoplasy is the development of similar physical features in species with different evolutionary histories due to similar environmental adaptations.

Answer:

homoplasy.
