17 Facts About Sympatric speciation

Sympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region.

Sympatric speciation is one of three traditional geographic modes of speciation.

Allopatric Sympatric speciation is the evolution of species caused by the geographic isolation of two or more populations of a species.

Parapatric Sympatric speciation is the evolution of geographically adjacent populations into distinct species.

In multicellular eukaryotic organisms, sympatric speciation is a plausible process that is known to occur, but the frequency with which it occurs is not known.

Sympatric speciation events are quite common in plants, which are prone to acquiring multiple homologous sets of chromosomes, resulting in polyploidy.

Sympatric speciation's exerts sensory bias when picking males by choosing those that have colors similar to her or those that are the most colorful.

Allochrony offers some empirical evidence that sympatric speciation has taken place, as many examples exist of recently diverged allochronic species.

Some time it was difficult to prove that sympatric speciation was possible, because it was impossible to observe it happening.

Since Mayr's heyday in the 1940s and 50s, mechanisms have been proposed that explain how Sympatric speciation might occur in the face of interbreeding, known as gene flow.

German evolutionary biologist Ernst Mayr argued in the 1940s that Sympatric speciation cannot occur without geographic, and thus reproductive, isolation.

Sympatric speciation stated that gene flow is the inevitable result of sympatry, which is known to squelch genetic differentiation between populations.

Sympatric speciation figured that if two ecological niches are occupied by a single species, diverging selection between the two niches could eventually cause reproductive isolation.

Investigating the possibility of sympatric speciation requires a definition thereof, especially in the 21st century, when mathematical modeling is used to investigate or to predict evolutionary phenomena.

Varying definitions of sympatric speciation fall generally into two categories: definitions based on biogeography, or on population genetics.

The difficulty in supporting a sympatric speciation hypothesis has always been that an allopatric scenario could always be invented, and those can be hard to rule out – but with modern molecular genetic techniques can be used to support the theory.

The term heteropatry semantically resolves the issue of sympatric speciation by reducing it to a scaling issue in terms of the way the landscape is used by individuals versus populations.
