Most new species come about in geographic isolation, or at due to least large-scale geographic distance, but a controversial hypothesis known as sympatric speciation, which occurs when a new species…

The small body size associated with the African pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, according to a new study, but since all African pygmy phenotypes do…

Descent with modification means that all life on Earth probably came from one common ancestor – a single-celled organism – We just have to speculate and create models for what it may have looked like…

Rangeomorphs were unlike any modern organism, which has made it difficult to determine how they fed, grew or reproduced, and therefore difficult to link them to any particular modern group. They…

Researchers working on biomimicry have produced the first structural color change in an animal by influencing evolution: They've changed the color of the butterfly Bicyclus anynana from brown to…

Researchers have been able to experimentally reproduce morphological changes in mice which have taken millions of years to occur. Through small and gradual modifications in the embryonic development…

One of the most diverse families in the ocean today, marine bivalve mollusks - called Lucinidae or lucinids - originated more than 400 million years ago in the Silurian period, with adaptations and…

During the winter of 1944, the Nazis blocked food supplies to the western Netherlands, creating a period of widespread famine and devastation. The impact of starvation on expectant mothers were also…

Parts of the primordial soup in which life arose have been maintained in our cells today, according to a new paper. The articles in the Journal of Biological Chemistry  discusses how cells in…

Models for the evolution of life are now being developed to try and clarify the long term dynamics of an evolving system of species. Specifically, a recent model proposed by Petri Kärenlampi from the…
