New research from the University of East Anglia shows that an evolutionary force known as 'sexual selection' can explain the persistence of sex as a dominant mechanism for reproducing offspring.
(Phys.org) —At some point, scientists may be able to bring back extinct animals, and perhaps early humans, raising questions of ethics and environmental disruption.
(Phys.org)—A team of researchers at Michigan State University has documented the step-by-step process in which organisms evolve new functions.
Biologists at the University of California, Riverside have found that voluntary activity, such as daily exercise, is a highly heritable trait that can be passed down genetically to successive generations.
(PhysOrg.com) -- A comparison of the genomes of 50 Tibetans and 40 Han Chinese shows that ethnic Tibetans split off from the Han less than 3,000 years ago and since then rapidly evolved a unique ability to thrive at high ...
(PhysOrg.com) -- The unexpected discovery of a new type of genetic variation suggests that natural selection - the force that drives evolution - is both more powerful and more complex than scientists have thought.
(PhysOrg.com) -- Does it matter if nature solves the same problem multiple ways? A NSF-supported study of lizard populations in White Sands, New Mexico has helped researcher Erica Rosenblum of the University of Idaho begin ...
