Genome sequenced: Orangutan DNA more diverse than human's, remarkably stable through the ages (w/ Video)
Among great apes, orangutans are humans' most distant cousins. These tree dwellers sport a coat of fine reddish hair and have long been endangered in their native habitats in the rainforests of Sumatra and ...

Genetic heritability may be hidden deeper than previously thought
(PhysOrg.com) -- Geneticists trying to find a link between the genes and traits such as height have until recently found genetic variants that account for only around 5% of the heritability of these traits. ...

Powerful genome barcoding system reveals large-scale variation in human DNA
(PhysOrg.com) -- Genetic abnormalities are most often discussed in terms of differences so miniscule they are actually called "snips" — changes in a single unit along the 3 billion that make up the entire string of human ...

Genome analysis of marine microbe reveals a metabolic minimalist
Flightless birds, blind cave shrimp, and other oddities suggest a "use it or lose it" tendency in evolution. In the microbial world, an unusual marine microorganism appears to have ditched several major metabolic pathways, ...

What drives our genes? Researchers map the first complete human epigenome
Although the human genome sequence faithfully lists (almost) every single DNA base of the roughly 3 billion bases that make up a human genome, it doesn't tell biologists much about how its function is regulated. Now, researchers ...

Researchers solve mystery of disappearing bird digit
Evolution adds and subtracts, and nowhere is this math more evident than in vertebrates, which are programmed to have five digits on each limb. But many species do not. Snakes, of course, have no digits, and ...
