Global trade has considerably accelerated biological invasions. The annual tropical teosintes, the closest wild relatives of maize, were recently reported as new agricultural weeds in two European ...

Plant and animal breeders have long used hybridization to transfer useful traits between species. But does the same process happen without human aid? In a new study in the June issue of American ...

Research on genetic mechanism of pig altitude-adaptations underlines the importance of introgression for the first time as a potential reason for pig adaptations to cold and hot environments. This ...

The importance of interspecific introgression as a source of adaptive variation is increasingly recognized. Theory predicts that beneficial genetic variants cross species boundaries easily even when ...

Hybrids, once treated as biological misfits, have been the secret saviors of many animal species in trouble. Reconciling that truth with conservation policies poses a challenge for science. In 2006, a ...

Explore adaptive allele fixation probability and how interbreeding between archaic and modern humans influences it. The central point of the paper is exceedingly simple. Haldane demostrated in 1927 ...

During the past decade, our human evolutionary tree has turned into something more resembling an unwieldy bush. Scientists have discovered swapped segments of DNA that we shared from mating between ...

Jan 26, 2015, Shenzhen, China -Scientists from Jiangxi Agricultural University, BGI and University of California published their latest research on genetic mechanism of pig altitude-adaptations in ...
