Speciation is the process by which new species forms and is the driving force of biodiversity. Since Darwin published On the Origin of Species, great efforts have been performed without interruption ...

New species can form without physical isolation Today, there are many examples of species being formed without isolation, such as during ongoing genetic exchange. This exchange should prevent two ...

Reproductive isolation is a biological process that prevents gene flow between populations or species, thereby maintaining or promoting genetic divergence and speciation. It operates through ...

Female giant water bugs lay their eggs on a male's back after mating and the male takes care of the eggs until the nymphs are hatched, a couple of weeks later. A study led by Dr. Tomoya Suzuki of ...

How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

Mayr was well known for his championship of the biological species concept and for asserting a predominant role for the geographic separation of populations in the diversification process that gives ...

Hendry's team observed that male river sockeyes are slimmer than their lake counterparts (to better deal with the river's strong current), while the female river sockeye are larger than their beach ...

Speciation is important because it increases biodiversity. A new thesis examines the speciation process in multiple marine species where different populations of the same species might evolve into two ...
