  • 1. Evolutionary biology is a scientific discipline that explores the processes underlying the diversity of life on Earth. It involves studying how organisms change over time through genetic variation, natural selection, and other mechanisms such as genetic drift and gene flow. By examining the patterns and mechanisms of evolution, evolutionary biologists seek to understand the history of life on our planet, as well as predict how species may adapt to changing environments in the future. Evolutionary biology provides insights into the interconnectedness of all living things and helps us appreciate the remarkable adaptations that have allowed life to persist and thrive in a constantly changing world.

    What is natural selection?
A) The process of organisms adapting to their environment.
B) The process of identical organisms competing for resources.
