Is nature mostly a tinkerer or an inventor?

The Krüppel-like factor and specificity protein (KLF/SP) genes are found across many species, ranging from single cell organisms to humans. This gene family has been conserved during evolution, because it plays a vital role ...

Team proposes new model for snake venom evolution

Technology that can map out the genes at work in a snake or lizard's mouth has, in many cases, changed the way scientists define an animal as venomous. If oral glands show expression of some of the 20 gene families associated ...

Study refutes theory linking cognition, genes and income

Researchers have cast doubt on a widely-held belief that connects family income with cognitive development, according to a new study published in Proceedings of the National Academy of Sciences.

Big brains are all in the genes

Scientists have moved a step closer to understanding genetic changes that permitted humans and other mammals to develop such big brains.

Genes tell story of birdsong and human speech

His office is filled with all sorts of bird books, but Duke neuroscientist Erich Jarvis didn't become an expert on the avian family tree because of any particular interest in our feathered friends. Rather, it was his fascination ...

Genomic and computational tools provide window to distant past

Out of the estimated 23,000 or more genes in the human genome, about 100 of them will differ—they will be present or not—between any two individuals. Genes lost or gained over time result from evolution and adaptation, ...
