Biology: Introduction to evolution and natural selection

Introduction to how groups of organisms evolve and how natural selection can lead to evolution.

Biology

Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.

Evolution and natural selection

Learn about evolution, the process in which groups of organisms change in their genetic makeup and heritable features over time. Natural selection is an important mechanism of evolution, one that can cause groups to become better suited to their environments over generations.
