Evolution

Bacteria living on opposite sides of a canyon have evolved to cope with different temperatures by altering the make-up of their 'skin', or cell membranes, write scientists who have found that…

Below is the final statement emerging from the Altenberg workshop, agreed upon by all 16 participants. Individual commentaries about the workshop will be posted on the KLI web site, and MIT Press…

"Survival of the fittest" is the catch phrase of evolution by natural selection. While natural selection favors the most fit organisms around, evolutionary biologists have long wondered whether this…

Genomic imprinting is a mechanism that regulates gene expression in the developing fetus and plays a major role in regulating its growth. Research published in Nature Genetics by a team of…

Hidden away in museums for more that 100 years, some recently rediscovered flatfish fossils have filled a puzzling gap in the story of evolution and answered a question that initially stumped even…

After taking a fresh look at an old fossil, John Flynn, Frick Curator of Paleontology at the American Museum of Natural History, and colleagues determined that the brains of the ancestors of modern…

Charles Darwin (1809-1882) opened his first notebook about "the species question" in 1837, not long after his return from the voyage of the Beagle.  By 1838, he had developed the basic outline…

In the current issue of Science, researchers from the European Molecular Biology Laboratory's European Bioinformatics Institute [EMBL-EBI] uncover systematic errors in existing methods that compare…

The newly sequenced genome of a dainty, quill-like sea creature called a lancelet provides the best evidence yet that vertebrates evolved over the past 550 million years through a four-fold…

Male homosexuality is difficult to explain under strictly Darwinian evolutionary models, because carriers of genes predisposing towards male homosexuality would be likely to reproduce less than…
