In distant islands, researchers are investigating how genomes are jumping between species. The genome exchange over species is known in the world of bacteria. But populations with limited living space are good subjects for research on how genomes jump between higher and more complicated species. The main genome transporter is retroviral. But there is also the possibility. That insects or some other more complicated parasites are transferring blood or some other cells between species. And those cells can also transport genomes between distances. There is the possibility that the DNA bites can jump between species. Those DNA bites can connect to the genomes of the new species. When animals are on distant islands. If they have no mates from the same species they can also make crossbreeds. In some distant islands lives their species. But there are also "islands" on dry lands things like Taita-hills in southern Africa offer a similar place for evolution with distant islands. T
