Through ____, a body part of an ancestor is modified differently in different lines of descent.

A) morphological divergence
B) adaptive divergence
C) morphological convergence
D) homologous evolution
E) natural selection

Morphological divergence refers to the modification of a body part in different ways in different lines of descent, leading to the development of diverse structures. This can result from various factors, including genetic drift, natural selection, and environmental pressures. Adaptive divergence (B) refers specifically to the development of different traits in response to different ecological niches, and may or may not involve morphological divergence. Morphological convergence (C) refers to the development of similar traits in distantly related species as a result of similar selective pressures. Homologous evolution (D) refers to the development of similar structures in different species as a result of shared ancestry. Natural selection (E) is the process by which certain traits become more or less common in a population over time, based on their impact on reproductive success. While it can lead to morphological divergence, it is not a specific term for this process.
