It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

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 ...

Speciation is a central and fundamental process in evolution that concerns the origin of reproductive isolation. The latest generation of genomic approaches provide remarkable opportunities to ...

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 evolutionary biologist Jochen Wolf was working from home when we first spoke, in April, 2020. Germany was under lockdown, and his lab, at Ludwig Maximilian University, in Munich, had been closed ...

Sexual selection and ecological speciation are interlinked evolutionary processes by which biodiversity arises. Sexual selection refers to differential reproductive success arising from mate choice ...

A simple change in species composition can impact the course of evolution: A research team from the University of Bern and the University of British Columbia in Canada shows that the presence of just ...

BATON ROUGE – In a study that sheds light on the origin of bird species in the biologically rich rainforests of South America, LSU Museum of Natural Science Director and Roy Paul Daniels Professor in ...

What is ecological speciation? -- Predictions and tests of ecological speciation -- A source of divergent selection -- A form of reproductive isolation -- A genetic mechanism to link selection to ...

A recently published study finds that competition for ecological niches limits the evolution of new species. Further, this study finds that speciation rate slows or even stops as available ecological ...

Speciation is a concept in evolutionary process wherein new and distinct species are formed. A new research discovered the reversal of speciation in ravens. The study, which is the product of an ...
