Male homosexuality can be explained through a specific model of Darwinian evolution
Scientists have found that the evolutionary origin and maintenance of male homosexuality in human populations could be explained by a model based around the idea of sexually antagonistic selection, in which genetic factors spread in the population by giving a reproductive advantage to one sex while disadvantaging the other.

Ancient antibody molecule offers clues to how humans evolved allergies
Scientists have discovered how evolution may have lumbered humans with allergy problems. They have discovered that chicken antibodies behaves quite differently from its human counterpart, which throws light on the origin and cause of allergic reactions in humans and gives hope for new strategies for treatment.

The symbolic monkey?
From paintings and photographs to coins and credit cards, we are constantly surrounded by symbolic artefacts. The mental representation of symbols – objects that arbitrarily represent other objects – ultimately affords the development of language, and certainly played a decisive role in the evolution of our hominid ancestors.

Woolly-mammoth gene study changes extinction theory
A large genetic study of the extinct woolly mammoth has revealed that the species was not one large homogenous group, as scientists previously had assumed, and that it did not have much genetic diversity. "The population was split into two groups, then one of the groups died out 45,000 years ago, long before the first humans began to appear in the region," said Stephan C. Schuster

Parasitoid turns its host into a bodyguard
There are many examples of parasites that induce spectacular changes in the behaviour of their host. Flukes, for example, are thought to induce ants, their intermediate host, to move up onto blades of grass during the night and early morning. There, they firmly attach themselves to the substrate with their mandibles, and are thus consumed by grazing sheep, the fluke's final host.

Galaxy Collision Debris a Laboratory to Study Star Formation
Researchers have shown that the process of star formation in areas of debris formed when two galaxies collide is essentially the same as star formation inside galaxies, meaning that the intergalactic medium can be a used as a simpler, more accessible laboratory for the study of stellar evolution.

Evolution of an imprinted domain in mammals
In general, which parent contributes a chromosome has no effect on the expression of the genes found on it. Exceptions to this rule are caused by “genomic imprinting”—modification of DNA, which means that gene expression is influenced by which parent the gene came from.

Invasive plant species can flourish better in their new homes than in their place of origin. The reasons for this can be genetic changes or the lack of herbivores such as insects that first have to adapt to the newcomers.

Scientists reveal the lifestyle evolution of wild marine bacteria
Marine bacteria in the wild organize into professions or lifestyle groups that partition many resources rather than competing for them, so that microbes with one lifestyle, such as free-floating cells, flourish in proximity with closely related microbes that may spend life attached to zooplankton or algae.
