The first complete mitochondrial genomes of endangered Hansenia species from the Qinghai-Tibet Plateau reveal varied genome ...

Contrary to what many people think, two species can hybridize naturally in the wild to give rise to a third species, a finding that fundamentally alters our understanding of the evolution of species ...

Genome-wide SNP analysis of lace bugs endemic to Japan's Ogasawara Islands has revealed a new species and clarified how ...

Spatial isolation is known to promote speciation—but LMU researchers have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed ...

It’s not every day that you get to see evolution happen before your eyes. Scratch that, until very recently, it wasn’t any day, since the process of speciation — in which one species splits into two ...

Arne O. Mooers is in the Department of Biological Sciences, Simon Fraser University, Burnaby, British Columbia V5A 1S6, Canada. Read the paper: An inverse latitudinal gradient in speciation rate for ...

What do seedless watermelon, salmon, and strawberries all have in common? Unlike most eukaryotic multicellular organisms that have two sets of chromosomes and are diploid, these organisms are all ...

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 ...

Adult male Iberá seedeater (Sporophila iberaensis) (left; image credit Abel Fleita) and adult male tawny-bellied seedeater (Sporophila hypoxantha) (right; image credit Sheela Turbek) live alongside ...

The tunnels of the London Underground are hot, dark, and damp. Crowds of warm-blooded humans congregate on the platforms. Stagnant pools of water collect beneath the tracks. The subterranean transit ...
