How hummingbirds evolved to fly at high altitude
(Phys.org) —High up in the Andes, numerous species of hummingbirds are thriving despite low levels of oxygen.
Promiscuous mouse moms bear sexier sons
University of Utah biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young: They attract more females by making more urinary pheromones, ...
Scientists uncover genetic similarities between bats and dolphins
The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, according to new research led by ...
Generosity leads to evolutionary success, biologists show
With new insights into the classical game theory match-up known as the "Prisoner's Dilemma," University of Pennsylvania biologists offer a mathematically based explanation for why cooperation and generosity have evolved in ...
Nice organisms finish first: Why cooperators always win in the long run
Leading physicists last year turned game theory on its head by giving selfish players a sure bet to beat cooperative players. Now two evolutionary biologists at Michigan State University offer new evidence ...
New research shows social monogamy evolved as result of competition
Social monogamy, where one breeding female and one breeding male are closely associated with each other over several breeding seasons, appears to have evolved as a mating strategy, new research reveals. It was previously ...
Resurrecting ancient proteins, team finds just two mutations set stage for evolution of modern hormone signaling
Evolution, it seems, sometimes jumps instead of crawls. A research team led by a University of Chicago scientist has discovered two key mutations that sparked a hormonal revolution 500 million years ago.
The Red Queen was right: We have to run to keep in place
Biologists quote Lewis Carroll when arguing that survival is a constant struggle to adapt and evolve. Is that true, or do groups die out because they experience a run of bad luck? Charles Marshall and Tiago ...
Evolution shapes new rules for ant behavior
In ancient Greece, the city-states that waited until their own harvest was in before attacking and destroying a rival community's crops often experienced better long-term success.
