What made humans ‘the fat primate’? Changes in DNA packaging curbed our body’s ability to turn ‘bad’ fat into ‘good’ fat 

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.

Move over, DNA: ancient proteins are starting to reveal humanity’s history

Proteins dating back more than one million years have been extracted from some fossils, and could help to answer some difficult questions about archaic humans.

Dark centers of chromosomes reveal ancient DNA — ScienceDaily

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.

DNA from 31,000-year-old milk teeth leads to discovery of new group of ancient Siberians 

Two children’s milk teeth buried deep in a remote archaeological site in north eastern Siberia have revealed a previously unknown group of people lived there during the last Ice Age. The finding was part of a wider study which also discovered 10,000 year-old human remains in another site in Siberia are genetically related to Native Americans — the first time such close genetic links have been discovered outside of the US.
