Isolation prevents mating between the populations and in time different mutations will accumulate in each population so much that they will no longer be able to mate. The inability to interbreed is one of the definitions of different species.
Mutation, isolation and natural selection. Google allopatric speciation.
The formation of a new species can result from various mechanisms, including natural selection, genetic drift, and isolation that lead to reproductive barriers between populations, preventing interbreeding. Over time, these factors can accumulate genetic differences and eventually result in distinct species.
natural selection
The formation of a new species can result from processes such as geographic isolation, genetic mutations leading to reproductive isolation, and natural selection favoring different traits in separate populations. Over time, these factors can drive genetic divergence between populations to the point where they are no longer able to interbreed successfully, leading to the development of a new species.
Speciation occurs when a population becomes reproductively isolated from other populations, leading to the development of distinct characteristics and eventual divergence into a new species. This process can be driven by various factors, including genetic drift, geographical isolation, and selection pressures that favor certain traits. Over time, these accumulated differences can become significant enough to prevent interbreeding and result in the formation of a new species.
Natural selection is the type of selection that can result in a branching evolutionary tree if it goes on long enough. This is because organisms may eventually evolve into a distinct species.
No, natural selection is believed to result in evolution.
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
Yes but only closely related species. If you isolated some canaries for years you could come up with a sub species of canary. but no matter how long the animals were isolated they would still be birds. they would not change into a species other than a bird species even if given millions of years.
Evolution
New species arise through a process called speciation, which can occur in several ways. This can happen through geographic isolation, where populations become separated and evolve independently, leading to genetic differences that eventually result in new species. It can also occur through genetic mutations, natural selection, and reproductive isolation, where individuals from different populations can no longer interbreed successfully.
Natural selection seems to be the only selection that can drive speciation with powerful adaptive change. Sexual selection seems to stay within the species and both gene flow and genetic drift do not seem to drive speciation very well.
