Paleontologists have documented the evolutionary adaptations necessary for ancient lobe-finned fish to transform pectoral fins used underwater into strong, bony structures, such as those of Tiktaalik roseae. This enabled ...

(Phys.org)—Researchers have discovered that a genetic difference in a 'switch', which causes over-activity in parts of the brain, may explain why some people could be more susceptible to conditions such as obesity and addiction, ...

New research on butterfly genomes has revealed that the genetic components that produce different splotches of colour on wings can be mixed up between species by interbreeding to create new patterns, like a "genetic paint-box".

A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, ...

(Phys.org)—A pair of researchers at MIT has developed what amounts to a "kill switch" for genetically modified organisms (GMOs). In their paper published in the journal Nature Communications, Brian Caliando and Christopher ...
Vincent Fleury, a researcher at the Paris Diderot University, studied the early stage of development when embryonic cells first form a flat sheet of cells before folding into a U-shape, resembling a folded pancake. He demonstrated ...
