3 de jun. de 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 101. 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
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.

3 de jun. de 2024 · 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.
Evolution, the flagship journal of the Society for the Study of Evolution, publishes articles in evolutionary biology focused on evolutionary phenomena and processes at all levels of biological organisation.
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.

8 de jun. de 2024 · Human evolution, the process by which human beings developed on Earth from now-extinct primates. The only extant members of the human tribe, Hominini, belong to the species Homo sapiens. The exact nature of the evolutionary relationships between modern humans and their ancestors remains the subject of debate.
