Optimal population size allows maximum predictability of evolution
(Phys.org)—Evolution in very large populations of plants, animals or fungi can be predicted far less easily than one would expect. This has been shown by research at the Institute for Theoretical Physics ...
Manufacturing genes to attack flu virus
An international research team has manufactured a new protein that can combat deadly flu epidemics.
Slow snails, fast genes: Predatory snails refine venoms through continuous gene duplication
(Phys.org) -- When tropical marine cone snails sink their harpoon-like teeth into their prey, they inject paralyzing venoms made from a potent mix of more than 100 different neurotoxins.
Evolutionary biology experiment may one day help with chronic diseases
Working to better predict general patterns of evolution, a University of Houston (UH) biologist and his team have discovered some surprising things about gene mutations that might one day make it possible ...
Evolution to the rescue: Researchers offer hope that species may adapt quickly to rapid environmental change
Evolution is usually thought to be a very slow process, something that happens over many generations, thanks to adaptive mutations. But environmental change due to things like climate change, habitat destruction, pollution, ...
Evolutionary kings of the hill use good, bad and ugly mutations to speed ahead of competition
Evolutionary adaptation is often compared to climbing a hill, and organisms making the right combination of multiple mutations both good and bad can become the king of the mountain.
Mutations: When benefits level off
Beneficial mutations within a bacterial population accumulate during evolution, but performance tends to reach a plateau. Consequently, theoretical evolutionary models need to take into account a "braking effect" in expected ...
