Evolution by Natural Selection

The process by which organisms change over time as a result of changes in heritable physical or behavioral traits, allowing them to survive and reproduce in a given environment.

Gregor Mendel

An Austrian monk considered the father of modern genetics for his work on pea plants, uncovering the fundamental laws of inheritance.

Darwinian Evolution

The theory of biological evolution developed by Charles Darwin, emphasizing natural selection as the primary mechanism for evolution where organisms that are better adapted to their environment tend to survive and reproduce.

Theory of Evolution

The scientific explanation for the diversity of life on Earth, proposing that species change over time through processes such as natural selection and genetic drift.
