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 ...

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 ...
