They can also be driven by natural selection in at least two ways. When two populations diverge from each other and encounter new - and different - environments they may adapt to these environments.

By enabling recombination between such diverged species, our method can be used to identify any intrinsic genetic incompatibilities, or speciation genes, to map the genetics underlying diverged phenotypes, or to produce recombinant hybrids with novel properties for commercial or research use. WebJan 2, 2024 · For most of the 20 th century, scientists believed that this reproductive incompatibility evolved gradually between species as a by-product of adapting to different ecological circumstances: if two species were geographically isolated, they would adapt differences based on their environment.
