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.
23 de abr. 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.
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.
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 - Species, Speciation, Adaptation: Darwin sought to explain the splendid multiformity of the living world—thousands of organisms of the most diverse kinds, from lowly worms to spectacular birds of paradise, from yeasts and molds to oaks and orchids.
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.
27 de abr. de 2022 · 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.
