They found their answer in the model of allopatricspeciation.
2
Rather, it is probable that most new brachiopod species of this age originated by allopatricspeciation.
3
I then made my usual linkage to ordinary allopatricspeciation, not to any novel or controversial mechanism of microevolution.
4
Our theory holds, as a defining statement, that ordinary allopatricspeciation, unfolding gradually at microevolutionary scales, translates to punctuation in geological time.
5
The two accounts invoke entirely different principles of saltational vs. allopatricspeciation, but the two arguments still employ an isomorphic logic).
6
We contend that a notion developed elsewhere, the theory of allopatricspeciation, supplies a more satisfactory picture for the ordering of paleontological data.
7
That reproductive separation between geographically overlapping but biologically compatible species -technically known as allopatricspeciation -is considered an important phase in species divergence.
8
Pelagic seabirds are highly mobile, reducing the likelihood of allopatricspeciation where disruption of gene flow between populations is caused by physically insurmountable, extrinsic barriers.
