There's a sex bias in evolution, according to an article in PLoS Genetics, and it's demonstrated by the fact that women have been more successful on average in passing their genes on to the next…

Scientists have decoded the genome of the Pristionchus pacificus nematode and gained valuable insight into the evolution of parasitism. In their work, the scientists have shown that the genome of…

Pregnancy is a biologically unusual situation where one organism lives and develops inside another that is genetically different. Ordinarily, the immune system identifies and destroys the dissimilar…

In 1970 the anthropologist Robert Ardrey published “The Social Contract, A Personal Inquiry into the Evolutionary Sources of Order and Disorder”. The theme of the book was that the modern concept of…

Bats' ability to echolocate may have evolved more than once, according to research published this week by Queen Mary, University of London scientists. Species of bat with the ability to echolocate do…

Subtle genetic changes that confer an evolutionary advantage upon a species, such as the dexterity characteristic of the human hand, while difficult to detect and even harder to reproduce in a model…

Yale molecular and evolutionary biologists in collaboration with Department of Energy scientists produced the full genome sequence of Trichoplax, one of nature's most primitive multicellular…

The grapevine (Vitis vinifera) is a widely cultivated crop that has been subjected to intensive breeding since the Neolithic period (from ~10,500 to ~6,000 years ago). The domestication of grapevine…

The ostentatious, sometimes bizarre qualities that improve a creature's chances of finding a mate may also drive the reproductive separation of populations and the evolution of new species, say two…
