In human evolution, changes in skin's barrier set Northern Europeans apart
The popular idea that Northern Europeans developed light skin to absorb more UV light so they could make more vitamin D – vital for healthy bones and immune function – is questioned by UC San Francisco ...
Modern men are wimps, according to new book
Rock-paper-scissors tournaments explain ecological diversity
According to classical ecology, when two species compete for the same resource, eventually the more successful species will win out while the other will go extinct. But that rule cannot explain systems such as the Amazon, ...
Darwin's dilemma resolved: Biologists measure evolution's Big Bang
A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the "Cambrian explosion" when most modern animal groups appeared between 540 and 520 million years ...
Study disputes notion that facial symmetry an indicator of health in children
Is trophy hunting affecting bighorn sheep evolution? Research says no
Are humans still evolving? Absolutely, says new analysis of long-term survey of human health
Although advances in medical care have improved standards of living over time, humans aren't entirely sheltered from the forces of natural selection, a new study shows.
DNA analysis reveals butterfly and moth evolutionary relationship
Study traces evolutionary origins of migration in New World birds
Every year, millions of birds make the journey from North America to Central and South America for the winter. But the evolutionary origins of this long-distance migration have remained opaque due to the ...
From one cell to many: How did multicellularity evolve?
In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the ...
Experiment gives insight into how species maintain diversity
How speed restricts evolutionary change of the vertebral column in mammals
One of the riddles of mammal evolution explained: the strong conservation of the number of trunk vertebrae. Researchers of the Naturalis Biodiversity Center and the University of Utah show that this conservation ...
Evolutionary roots of self control: Study of 13 primate species links 'intertemporal choice' to natural selection
A chimpanzee will wait more than two minutes to eat six grapes, but a black lemur would rather eat two grapes now than wait any longer than 15 seconds for a bigger serving.
Does germ plasm accelerate evolution?
Scientists at The University of Nottingham have published research in the leading academic journal Science that challenges a long held belief about the way certain species of vertebrates evolved.
