WebThe definition of a species as a group of interbreeding individuals cannot be easily applied to organisms that reproduce only or mainly asexually. Also, many plants, and some animals, form hybrids in nature. Hooded crows and carrion crows look different, and largely mate within their own groups — but in some areas, they hybridize.

WebMar 5, 2024 · A species is a group of organisms that can breed and produce fertile offspring together in nature. For a new species to arise, some members of a species must become reproductively isolated from the rest of the species. This means they can no longer interbreed with other members of the species. How does this happen? WebSpecies are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
