Models of adaptive speciation are typically concerned with demonstrating that it is possible for ecologically driven disruptive selection to lead to the evolution of assortative mating and hence ...

Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of "On the Origin of Species" debate continues on the mechanisms of speciation. New ...

‘Hybrid speciation’ implies that hybridization has had a principal role in the origin of a new species. The definition applies cleanly to hybrid species that have doubled their chromosome number ...

In the first experiment of its kind conducted in nature, evolutionary biologists have come up with strong evidence for one of Charles Darwin's cornerstone ideas -- adaptation to the environment ...

Mimicry has had a significant historical influence as a tractable system for studying adaptation and is known to play a role in speciation. Here, we discuss recent theoretical treatment of adaptive ...

Assortative mating is critical for reproductive isolation during speciation; however, the mechanisms underlying mating preferences are often unknown. Assortative mating can be mediated through ...

Evolutionary branching in a classical model for sympatric speciation -- Adaptive diversification due to resource competition in asexual models -- Adaptive diversification due to resource competition ...

There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands. All of them evolved from one ancestral species, which colonized the islands ...

While Madagascar is famous for its incredible diversity of plants and animals, a new study suggests that the island’s rate of speciation has slowed to a crawl. The research, published last week in the ...

Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of his famous book, 'On the Origin of Species', debate still continues on the ...

Some 150 years after the publication of Darwin's famous book, 'On the Origin of Species', debate still continues on the mechanisms of speciation. Some 150 years after the publication of Darwin's ...
