A duel between mathematical models supports the reigning theory of the genetics of altruism
It isn't that often that a scientific controversy is featured in the New Yorker, but in 2012 an article titled "Kin and Kind" describing a tempest over a biological theory appeared in its pages. ...
Beards as badges of honour?
Are beards 'in' again because guys are under pressure? Maybe.
'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 ...
Men's preference for certain body types has evolutionary roots
A psychology study from The University of Texas at Austin sheds new light on today's standards of beauty, attributing modern men's preferences for women with a curvy backside to prehistoric influences.
Biologists show how the evolution of physical traits can influence behavior
For many male African cichlid fish, the best way to attract a mate is to build a really nice pit or sand castle on a lake bottom.
Rich diversity of present-day beetles may be due to extinction resistance
Today's rich variety of beetles may be due to an historically low extinction rate rather than a high rate of new species emerging, according to a new study. These findings were revealed by combing through ...
Oldest known sponge found in China
Conifers' helicoptering seeds are result of long evolutionary experiment
The whirling, winged seeds of today's conifers are an engineering wonder and, as University of California, Berkeley, scientists show, a result of about 270 million years of evolution by trees experimenting ...
Big toe's big bone holds evolutionary key
Our skeletons hold tell-tale signs that show that human bipedalism – walking upright and on two feet – are unique to humans especially when compared to our closest living relatives, apes. Exactly when ...
New research shows that the Asian monsoon rains played a key role in the evolution of mammals
New research has shown that the Asian monsoon rains played a key role in the evolution of mammals.
Progeny of old parents have fewer offspring
Reproduction at old age involves risks that may impact one's own life and may impose reduced biological fitness on the offspring. Such evidence, previously obtained in humans and other taxa under laboratory ...
Love, love me do: Male beetles that have more sex are more insecure, study shows
Males that mate more often are more insecure about their social status than those mating less, according to new research on the behaviour of burying beetles.
Grand tree of life study shows a clock-like trend in new species emergence and diversity
Temple University researchers have assembled the largest and most accurate tree of life calibrated to time, and surprisingly, it reveals that life has been expanding at a constant rate.
Study identifies first-ever human population adaptation to toxic chemical, arsenic
High up in the high Andes mountains of Argentina, researchers have identified the first-ever evidence of a population uniquely adapted to tolerate the toxic chemical arsenic.
