- Evolution Is Driven By Gene Regulation
It is not just what’s in your genes, it’s how you turn them on that accounts for the difference between species — at least in yeast — according to a report by Yale researchers in this week’s issue of Science. “We’ve known for a while that the protein codin ...

- Gene Regulation Sets Humans Apart
Humans and chimpanzees share 99 percent of their genetic makeup but how those genes are used is the key difference, say Duke researchers. In two major traits that set humans apart from chimps and other primates – those involving brains and diet – gene regu ...

- Adaptation Drives African Fishes Along Different Evolutionary Paths
Natural selection has driven two closely related species of fish in Lake Malawi down different evolutionary paths- even though they live side by side. An international team of scientists from Canada (Université Laval), the U.K. (University of Hull, Cardiff ...

- Why Men Matter In Evolution
Dating younger women is not just about trophy wives, say the researchers behind the PLoS paper, "Why Men Matter: Mating Patterns Drive Evolution of Human Lifespan." It's also about understaning evolution. Male reproduction begins and ends la ...

- An Evolution Reason Men Should Date Younger Women
In evolutionary terms, the difference between 2.1 and 2.2 children is a lot more important than the small difference sounds, especially as it accumulates over time. A new study in Royal Society Biology Letters says that achieving that maximum offspring cou ...

- Evolution Of Genomic Imprinting- It's Not Sex Chromosomes
How we come to express the genes of one parent over the other is now better understood through studying the platypus and marsupial wallaby – and it doesn’t seem to have originated in association with sex chromosomes. New research published in BMC Evolution ...
