What must happen in order for new species to evolve?

Answer 1

Reproductive isolation.

If a species is divided into two groups, which cannot interbreed, then each group will gradually adapt to their new environment . Eventually the two groups will be so different that members from the different groups can no longer mate with one another and produce fertile offspring. This means that the two groups have become different species.

Answer 2

to mate with another of its kind and for the offspring to mate with a relative, for example say a blue racer mates with another blue racer and their offspring goes and mates with a gecko and that is how they evolve.

Answer 3

You first typically need a population of organisms that split off from its original group (e.g., due to migration), thus isolating the two gene pools. Then these two different gene pools have to become different from each other, due to natural selection, genetic mutation, and genetic drift. If after many, many generations, you're left with two populations that are so different from each other (or at least so different than the original population they came from) that they can no longer be considered the same species, then you've got a new species.

Answer 4

New species can evolve through a process called speciation, which occurs when a population becomes isolated geographically or reproductively, leading to differences in the gene pool over time. This can happen through factors such as natural selection, genetic drift, and mutations, ultimately resulting in the formation of distinct species.

Answer 5

Evolution.
