(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 ...

Scientists discover at least 11 examples of sympatric speciation on Lord Howe Island. How does a single species divide into two new species? For decades, the prevailing idea among evolutionary ...

Or is so-called sympatric speciation also possible -- the evolutionary divergence of a population within the same geographical area? Only few examples of sympatric speciation are known worldwide, and ...

One of the world's best examples of sympatric speciation, when two species from a single ancestor form in the absence of a geographical barrier, has been found among the swaying palm trees on ...

Aside from well-known mechanisms of chromosomal polyploidy, examples of homoploid sympatric speciation in plants are rare. Savo-lainen et al. 1 present interesting comparative morphological, ...

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 ...

The offspring of crosses between related species can sometimes fill a new environmental niche, and such hybridizations may even lead to speciation. In the 20th century, animals such as mules and ...

The Midas cichlid fish from the crater lakes of Nicaragua are one of the the best known examples for sympatric speciation. They evolved from a source population into a variety of independent species ...

Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all ...

German researcher Christian Rabeling was digging up ant colonies on a college campus in Brazil when he found something unexpected—certain ants appeared smaller and shinier and had wings. Rabeling soon ...
