Answer:
The basic idea of biological evolution is that populations and species of organisms change over time.
Explanation:
Today, when we think of evolution, we tend to relate this idea to a person: the British naturalist Charles Darwin.

In it, he proposed that species evolve and that all living things can trace their ancestry to a common ancestor. Darwin also suggested a mechanism for evolution: natural selection, in which inheritable traits that help an organism survive and reproduce, become more common in a population over time.
