20 de may. de 2024 · Evolution is the process of descent with modification that explains the origin and diversity of living things on Earth. Learn about the evidence, history, types, and examples of evolution from Britannica's experts.
In the longer term, evolution produces new species through splitting ancestral populations of organisms into new groups that cannot or will not interbreed. These outcomes of evolution are distinguished based on time scale as macroevolution versus microevolution.
Through the process of descent with modification, this common ancestor gave rise to the diverse species that we see documented in the fossil record and around us today. Evolution means that we’re all distant cousins: humans and oak trees, hummingbirds and whales.
Evolution is a process that results in changes in the genetic content of a population over time. Explore the mechanisms of microevolution and macroevolution, and how they shape biodiversity and ecology.
9 de feb. de 2024 · Learn how species evolve through natural selection and adapt to different factors in their environment. Explore examples of evolution in finches, coral reefs, humans, and crocodiles with activities and videos.
How do new species form? This article reviews the historical and modern views on speciation, from Darwin to genomics, and explores the role of geography, genetics, and natural selection in the process.
