Past research has demonstrated that each mammal individual has a certain smell that separates it from its peers. This comes in very handy for a large number of animals in a vast series of actions, such as choosing companions for mating purposes, or delimiting one's own territory. The odor is eliminated by means ... |

Viruses have always been part of our evolutionary process, constantly mutating in order to defeat the immune system, at the same time triggering changes in the structure of the DNA, which eventually gave us defense mechanisms that still work today. Some types of viruses, known as retroviruses, even have the capabilit... |

A study conducted in the UK suggests that as much as 25 percent of the population of the country is protected against alcohol-related cancers as a result of having certain genetic mutations that allows the body to eliminate the alcohol much faster than in the case of the rest of the population. This in turn alters th... |

The last Tasmanian tiger, thylacine, died in captivity in 1936 at Hobart Zoo after being hunted to extinction during the early 1900s. Fortunately, some thylacine pouch young and adult tissues were preserved in alcohol by museums around the world. One of those is Museum Victoria in Melbourne which donated some samples... |

We know that boys have XY sex chromosomes, while girls have XX. However, in some cases, newborn girls can be XY. A new research published in the Nature journal clarifies why some XY embryos, instead of being born as males, develop ovaries and evolve as girls: it's because of a gene called Sox9, involved in forma... |

The platypus is by far the strangest mammal, with its bird-like bill and reptile traits.

An abused child does not have only an impaired behavior, but also a structurally different brain. That happens because early child abuse appears to permanently change gene expression in the brain, as pointed by a postmortem investigation of suicide victims, recently published in the Nature Neuroscience journal.

The face is one of the few things you cannot, under any circumstance, neglect in a new possible mate. For humans, the face is an important source of mating and social information. By casting only one glance, you can see if a face is attractive or not. Many studies have focused on issues like symmetry and the differen... |

A new research published in Current Biology comes to confirm the role zoos, farms and private collections could have in saving menaced species: it seems that up to 50% of the captive tigers could be "purebred" members of an endangered subspecies. This finding may boost the number of animals to be involved in breeding... |

Our closest living relatives are chimpanzees and bonobos.

The difference between Danny DeVito and Dolph Lundgren is given only by genes. So far, only two of these genes have been known.

Sex is considered the engine of the evolution. Without sex, we would all be similar clones. Sex brings diversity, but also it can repair the effects of negative mutations. Healthy genes from one parent can counteract the presence of a damaged (mutated) gene from the other parent, resulting healthier offspring. Thus, ... |

Blue or almost black, slate-gray, golden or violet or fainted green. Our eye color depends on that of our parents or grandparents. This is one of the strictest genetically inherited traits. No matter the hues, eyes are divided in two types depending on their color: dark (brown or black) and light (blue or green). The... |

Just having a XY sex chromosome formula won't make you a man. Nor the XX formula makes you a woman. Increasing evidence shows that human sex is not caused by sex chromosomes, but by genes placed on those chromosomes. Over 50 genes involved in sex expression have been found so far. 7 operate in the brain even bef... |

It is simplistic to differentiate people in races based on the skin tones. What we call Blacks can be separated in many races, equally or not related between them and other races; the term White is misleading too. In the case of the so-called Mongoloid race, skin tones vary significantly. But no matter what, skin col... |

Our scalp has about 100,000 hair follicles. About 100 of them stop working daily and, consequently, hairs fall. But at the same rate they are replaced. Of course, this is the case when baldness is not encoded in your genes. Scientists are still trying to understand the pathway of baldness genetics, but two recent re... |

We know that twins are of two types. Some twins come from two different eggs fecundated by two different sperms (this means they can have different genders); they are just ordinary brothers born at the same moment. This are called dizygotic or non-indentical twins and, like any brothers, they share usually 40-60 % of... |

We know that marrying your first degree cousin is not good.

We migrated from Africa about 100,000 years ago and, since then, we have colonized the whole Earth, adapting to new environments and diets. It is clear that this accelerated an evolution in our physical traits, in the genes connected to skin color or stature, as means of adaptation to novel habitats. A new research p... |

Nature played with one of our ancestors, and it caused the blue eye color to appear; and now, women are in love with the blue eyes of Brad Pitt and men with those of Kristanna Loken.

Humans come as boys or girls, but some organisms do not and without being hermaphrodites, they still have sex.

The ancestral sex-d... |

First humans might have been black, but once they started the migration out of Africa about 100,000 years ago, their skin color gradually paled, in the new colder climes. 10,000 years ago, at the end of the Ice Age, marine stickleback fish started to colonize lakes and streams in Europe, Asia and North America, and t... |
