How did humans get to be so much fatter than our closest primate relatives, despite sharing 99% of the same DNA? A new study suggests that part of the answer may have to do with an ancient molecular shift in how DNA is packaged inside fat cells, which curbed our body’s ability to turn ‘bad’ white fat into ‘good’ brown fat.

Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have changed during human evolution.
