Geneticists solve 40-year-old dilemma to explain why duplicate genes remain in the genome
Geneticists at Trinity College Dublin have made a major breakthrough with important implications for understanding the evolution of genomes in a variety of organisms.
The ethics of resurrecting extinct species
(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.
A closer look at the GM debate
Genomics analysis demonstrates natural selection at work
(Phys.org)—A team of researchers at Michigan State University has documented the step-by-step process in which organisms evolve new functions.
Did the universe evolve to make black holes?
(Phys.org) —The maths underpinning Darwin's theory of natural selection could explain how the universe may be 'designed' to make black holes.
Time in a bottle: Scientists watch evolution unfold
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 ...
Evolution of new species requires few genetic changes
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 ...
Genetic chip will help salmon farmers breed better fish
Atlantic salmon production could be boosted by a new technology that will help select the best fish for breeding.
A new type of genetic variation could strengthen natural selection
(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 ...
Castaway lizards provide insight into elusive evolutionary process
A University of Rhode Island biologist who released lizards on tiny uninhabited islands in the Bahamas has shed light on the interaction between evolutionary processes that are seldom observed.
Capacity for exercise can be inherited, biologists find
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.
Immune system study could help conserve endangered species
(Phys.org) —A study by University of Georgia ecologists has found that diversity in mammal immune system genes may have more to do with the opportunity to choose a mate than with exposure to parasites.
Dead seals serve conservation boost
Scientists have used genetic testing on animals that died of natural causes for the first time, potentially boosting efforts to save endangered species.
Researchers show gene controlling coat color in mice mutated nine times, results shed new light on how evolution works
For deer mice living in the Nebraska Sandhills, color can literally be the difference between life and death.
