Geographic Isolation
Reproductive isolation
Geographic isolation.
Isolation
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
reproductive, behavioral, geographic, and temporal
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
Speciation. Geographic isolation occurs when a population is divided by a physical barrier, leading to the development of distinct species over time. Reproductive isolation refers to barriers that prevent individuals from different populations from successfully mating and producing viable offspring.
