Species
No, it affects male/female and also all race/ethnic groups equally!
Any time there's a barrier... physical, geographical (distance), or behavioral... between the two that means they no longer reproduce with each other but only within their own group.
Isolated:you sre at a place you don't want to be ANSWER: An isolated settlement is one that is cut off from other civilization, trade routes, or outside help.
It is estimated that at least a few thousand people live in an isolated dwelling. Some people really do not like to be around other people.
They become separate species.
the answer is SPECIES BECAUSE the common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology.
Biological Species Concept, which defines species as groups of interbreeding populations that are reproductively isolated from other groups.
Actually, nothing happens. But if the distances increase between the groups, then they become geographically diverse and hence there will be a greater chance of development of a new species from the isolated groups. Other factors also influence this, like the presence of already existing populations in the new area.
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
Amphibians are not herd animals. Toads and other amphibians live alone except when they are reproducing.
The dominant mode of speciation among most groups of organisms is allopatric speciation. This occurs when populations of a species become geographically isolated from each other and over time, genetic and environmental differences accumulate, leading to the formation of distinct species.
Isolation can be due to behavioral, geographical, or temporal barriers.
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
Yes. As an example, a species may come in two varieties that differ in appearance. Many animals prefer to mate with individuals that resemble them. Sexual selection can therefore cause two populations to diverge.
