Understanding Evolution: Process and Key Concepts

Subject : Biology

Question:

Which of the following explains the process of evolution?

A. A process of change in a population through genetic variation over time.

B. The genetic variation within a species.

C. A change in one species that results from a change in a different species with which it interacts.

Expert Verified Solution:

The correct answer is A. A process of change in a population through genetic variation over time.

Evolution is a fundamental biological process that explains how species change over time. It occurs when there is a change in the genetic makeup of a population, which can lead to the development of new traits and characteristics. These changes accumulate over generations, often resulting from natural selection, where advantageous traits become more common in the population. This process drives the diversity of life on Earth and explains how species adapt to their environments.
