WebFor the longest time, I've held the assumption that to be a member of a species is to have innate (mostly genetic) components. I.e., without a specific trait (s) (e.g. strips on zebra, white fur on polar bears, Indian rhinos with one horn), that organism is not a member of a given species. I'm guessing this view is also held by the general ... WebEvolution is the process by which small changes in organisms occur over long periods of time and new species are formed.

WebDarwin's Theory of Natural Selection has been divided into five parts to explain clearly how evolution happens in nature. 1. Organisms produce more offspring than actually survive. … WebSeparate groups of organisms belonging to the same species may adapt in different ways to better exploit diverse environments or resources. They also may evolve varied characteristics for attracting mates. That is, different groups evolve in different directions.

WebNew alleles originate by mutation, a permanent change in the nucleotide sequence of DNA. Mutation is the ultimate source of the genetic variation that serves as raw material for evolution. In multicellular organisms, however, only mutations in cells that produce gametes can be passed to offspring and affect a population ' 3 genetic variability. WebNew species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed. Darwin envisioned speciation as a branching event.
