Nocturnal animals need their noses to stay alive. Mice, among others, depend on their impressive olfactory powers to sniff out food or avoid danger in the dark.
A survey of 142 men and 516 women with experience in field studies in anthropology, archaeology, geology and other scientific disciplines reveals that many of them – particularly the younger ones – suffered or witnessed ...
Though some might disagree, most biologists think the purpose of sex is to create diversity among offspring. Such diversity underpins evolution, enabling organisms to acquire new combinations of traits to adapt to their environment.
The essence of male beauty is down to the way males use their genes rather than what genes they have, according to a new study into the sexual attractiveness of turkeys.
From the elephant to the mayfly, biologists say there is a general rule about longevity: the bigger the animal, the longer it lives.
When it comes to sex among guppies, competition is high for those at the top of the game. To get around this predicament, a recent study has shown, guppies use trickery.
(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.
Females play a larger role in determining paternity than previously thought, say biologists in Syracuse University's College of Arts and Sciences. Their findings are the subject of a new paper titled "Female mediation of ...
New research from evolutionary biologists at the University of Toronto shows that the male guppy grows claws on its genitals to make it more difficult for unreceptive females to get away during mating.
Sexual reproduction is costly to those organisms that depend on it, like humans. For starters, only half of the population can bear offspring and the other half has to work hard to make sure they're included in the future ...
