Which of the following statements is compatible with Darwin’s theory of evolution? much of the variation in individuals of a pop
rjkz [21]

Answer:

A. much of the variation in individuals of a population is heritable

Explanation:

Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.

Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
