For a while now, researchers have been arguing that marriage reduces aggressive and illegal behaviors in men, and now, a Michigan State University behavior geneticist, found that the reason for this was matrimony itself but also the fact that less 'antisocial' men are simply more likely to get married. S... |

Europe may be called the Old Continent, but its current population has a rather recent origin. And a new research published in the journal "Nature" shows that white European people are less genetically diverse, carrying more harmful mutations, than the black Africans. The results point that a population "bottleneck" ... |

Large shoulders, perfect smile, good sense of humor or a trusty person? No matter what makes a man attractive, women worldwide want the same in men. And this rule applies to the animal kingdom as well: all females are attracted by the same male characteristics, specific to a species, no matter if it's about som... |

Males change faster than females. Just look at a peacock's tail feathers compared to the plain peahen. In most species, males are brighter and better singers, competing for getting as much as possible mates. This way they experience sexual selection. This overdrive compared to females puzzle the scientists, as t... |

Now we know why Barry White was nicknamed "The Walrus of Love". A new research found that men with lower-pitched voices father more children than those with high-pitched voices. Women found in the fertile period seem to select men with low-pitched voices.Previously, the team led by David Feinberg, assistant professo... |

What makes a typically 'macho' face? Large jaws, well-defined cheeks and large eyebrows are hot or at least were in the eyes of some naughty women ancestors, as a team at the Natural History Museum has found. It is well known that facial attractiveness played a crucial role in the sexual selection during hu... |

It seems easy for females: they are passive, just waiting for the pretenders and choosing the one that pleases them. But that is not always true, at least for female iguanas.A team led by Maren Vitousek of Princeton University discovered that female Galpagos marine iguanas wasted a lot of energy picking a mate from a... |

Ancient ferocious Celtic warriors knew why they put horns on their helmets (it was the Celts, not the Vikings, that adorned their helmets!). Because a bigger horn means you are a better male. This is real, at least in the case of the alpine ibex. A new research found a perfect correlation between horn size of mature ... |

Women are deceiving, men first hit and after that ask. This characterized us ever since we were just some "monkeys" in the forest, also shaping our brains differently. A new study published in the online journal BMC Biology shows that brain structures have developed differently in primate males and females due to div... |

Sex can be dangerous. And in some cases the females are the ones putting themselves at risk. In the case of the fiddler crabs females have to expose themselves to the predators to get some loving moments. That's why they seem to take very seriously the sexual signaling as discovered by a mix team from Seoul Nat... |

Humans have a very annoying quality: pride. And they like to praise themselves as being the most evolved species. But a new research has found that since the human-chimp split about 4 million years ago, the chimpanzee genome evolved at higher pace that the human one. This challenges that our large brains, cognitive ... |

There is a common concept amongst biologists about sexual selection and that many exaggerated male traits are the result of it. For example, sexual selection is regarded behind the peacock's tail or deer's antlers. But a team of Exeter and Cambridge universities has proven a common example of sexual select... |

Shallow-explaining creationists cling on an apparent paradox of the evolutionary theory: why do un-attractive persons exist?This mystery puzzled evolutionary scientists for years ... if "good" genes are favored by evolution, why are individuals so different? The "lek paradox", that sexually-selecting species like hum... |

Scientists have tried to explain for quite some time now why male ungulates possess such large antlers and horns. When Charles Darwin emitted his famous theory of evolution and natural selection, he pointed out that the size of male ungulate antlers and horns signals a male's individual fitness, and thereby are ... |
