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.
Charles Darwin's theory on evolution still holds true despite lower mortality and fertility rates in the modern world, according to new research by the University of Sheffield.
(Phys.org) —The maths underpinning Darwin's theory of natural selection could explain how the universe may be 'designed' to make black holes.
'Attractive' male birds that mate with many females aren't passing on the best genes to their offspring, according to new UCL research which found promiscuity in male birds leads to small, genetic faults in the species' genome.
Only a few genetic changes are needed to spur the evolution of new species—even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately ...
(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.
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers ...
