Population benefits of sexual selection explain the existence of males
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.
'Most attractive' male birds don't have the best genes
'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 ...
Consistency is the key to success in bread baking and biology
Whether you're baking bread or building an organism, the key to success is consistently adding ingredients in the correct order and in the right amounts, according to a new genetic study by University of ...
Evolution continues despite low mortality and fertility rates in the modern world
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.
New computation method helps identify functional DNA
Striving to unravel and comprehend DNA's biological significance, Cornell scientists have created a new computational method that can identify positions in the human genome that play a role in the proper ...
The cat's meow: Genome reveals clues to domestication
Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome by researchers at Washington ...
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.
How are hybridized species affecting wildlife?
Researchers who transplanted combinations of wild, domesticated, and domesticated-wild hybridized populations of a fish species to new environments found that within 5 to 11 generations, selection could remove ...
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.
Fly dreams and the boundaries of evolutionary science
Controlling parasitic worms with genetic selection
Helminths are gastrointestinal parasitic worms that have become a major concern and source of economic loss for sheep producers around the world. A new article published today in the Canadian Journal of Animal Science review ...
Rapid evolution of novel forms: Environmental change triggers inborn capacity for adaptation
In the classical view of evolution, species experience spontaneous genetic mutations that produce various novel traits—some helpful, some detrimental. Nature then selects for those most beneficial, passing ...
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 ...
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.
