The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

Theoretical studies indicate that while sympatric speciation is possible, the necessary conditions are considerably more stringent than for speciation in allopatry. Sympatric speciation encounters two ...

This fully-resourced lesson describes how reproductive isolation can lead to allopatric and sympatric speciation. The engaging PowerPoint and accompanying resources have been designed to cover point 3 ...

(Phys.org)—A research team working in Israel has found what might possibly be an example of evolutionary divergence in action – and it's not due to a natural barrier. In their paper published in the ...

Reinforcement is a controversial mechanism of speciation in which reproductive isolation is strengthened in response to maladaptive hybridisation. In a recent paper published in Nature, Hoskin et al ...

This fully-resourced lesson explores how new species arise when changes in the gene pool of two populations prevents members from interbreeding and producing fertile offspring. The engaging PowerPoint ...

It's a bit like a character in a movie going off and having adventures that change him so drastically that when he returns, the folks in his hometown no longer recognize the way he looks and behaves.
