| I didn't mention punctuated equilibrium or allopatric speciation either, because it isn't relevant to the matter at hand. |
|
| Such barriers are some kind of geographic feature which isolates parts of populations, and leads to allopatric speciation. |
|
| Relatively large genetic distances between populations suggest long periods of isolation and allopatric speciation. |
|
| In the classic case of allopatric speciation, gene flow is eliminated completely because of a geographic barrier. |
|
| Thus, the spatial isolation of sister species is a signature of allopatric speciation. |
|
| There are always potential exceptions to allopatric speciation, such as speciation occurring without geographic isolation, which is termed sympatric speciation. |
|
| The Congo's formation may have led to the allopatric speciation of the bonobo and the common chimpanzee from their most recent common ancestor. |
|
| The Grande Coupure is characterized by widespread extinctions and allopatric speciation in small isolated relict populations. |
|
| This process is known as allopatric speciation. |
|
| The allopatric speciation model fits our data best. |

|
| This differs from allopatric speciation in that the isolated populations are numerically much smaller than the parental population. |
|
| In allopatric speciation, individuals of a species become geographically isolated from each other by external factors such as mountains or estuaries. |
|
| The most common in animals is allopatric speciation, which occurs in populations initially isolated geographically, such as by habitat fragmentation or migration. |
|
| The problem does not occur in allopatric speciation with geographically separated populations, which can diverge with different sets of mutations. |
|
| This occurs most easily in allopatric speciation, where populations are separated geographically and can diverge gradually as mutations accumulate. |
