Jul 24, 2024 · Evolution - Diversity, Extinction, Adaptation: The current diversity of life is the balance between the species that have arisen through time and those that have become extinct. Paleontologists observe that organisms have continuously changed since the Cambrian Period, more than 500 million years ago, from which abundant animal ...

Aug 6, 2024 · Extinction, in biology, is the dying out or extermination of a species. It occurs when species are diminished because of environmental forces (natural or human-made) or because of evolutionary changes in their members. Learn more about mass extinctions and modern extinctions.
Jul 24, 2024 · 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.
1 day ago · Species extinction occurs when the death rate over the entire species exceeds the birth rate for a long enough period for the species to disappear. It was an observation of Van Valen that groups of species tend to have a characteristic and fairly regular rate of extinction.
Jul 24, 2024 · Species life-history traits, paleoenvironment, and biotic interactions likely influence speciation and extinction rates, affecting species richness over time. Birth-death models inferring the impac...
Aug 8, 2024 · The ever-increasing access to genomes of species of conservation concern, or even extinct species, presents unique opportunities to understand the role that genetic diversity has on population viability.
Aug 2, 2024 · Fortunately, there is some evidence for rapid adaptation (when evolutionary processes occur on ecological timescales), especially in species with short generation times 2,5,6.
