Apr 23, 2024 · Evolution, theory in biology postulating that the various types of living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. The theory of evolution is one of the fundamental keystones of modern biological theory.

Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.
An introduction to evolution: what is evolution and how does it work? The history of life: looking at the patterns– Change over time and shared ancestors. Mechanisms: the processes of evolution– Selection, mutation, migration, and more. Microevolution– Evolution within a population. Speciation– How new species arise.
Biological evolution is the process of change and diversification of living things over time, and it affects all aspects of their lives— morphology (form and structure), physiology, behaviour, and ecology. Underlying these changes are changes in the hereditary materials.
Evolution is a process that results in changes in the genetic content of a population over time. There are two general classes of evolutionary change: microevolution and macroevolution....
