sympatric speciation

Genetic evidence suggests that these probably were the result of sympatric speciation.

You need to do some research on allopatric and sympatric speciation.

This evolutionary process is believed to be one of the main driving forces behind sympatric speciation.

And scientists have discovered a handful of cases in which, they argue, sympatric speciation took place.

Mathematical models have suggested this process - known as sympatric speciation - can happen under certain conditions.

Perhaps even the sound an animal produces is enough to set off what is known as sympatric speciation.

In sympatric speciation, there is no geographic constraint to interbreeding.

Debated almost since the beginning of popular evolutionary thought, sympatric speciation is still a highly contentious issue.

In sympatric speciation, species diverge while inhabiting the same place.

Sympatric speciation can make the same claim.

Reinforcement is required for both parapatric and sympatric speciation.

This is an example of sequential sympatric speciation.

Some evidence suggests that sympatric speciation is occurring.

Reinforcement, like sympatric speciation (see Box 1), has charisma.

He stresses that the divergences which occur resulting from the conflict could lead to sympatric speciation.

Finally, in sympatric speciation species diverge without geographic isolation or changes in habitat.

Yet, recent research has begun to indicate that sympatric speciation is not as uncommon as was once assumed.

If these organisms are closely related (e.g. sister species), such a distribution may be the result of sympatric speciation.

It and Howea forsteriana probably evolved from a common ancestor through sympatric speciation.

It is contrasted with sympatric speciation where speciation takes place even though all the members live in the same area.

But sympatric speciation has drawn fierce criticism.

This constitutes a possible example of an early step towards the emergence of a new species, a case of sympatric speciation.

The genetic evidence from Apoyo supports a hypothesis that the six known species of the lake evolved via sympatric speciation.
