LANDMARKS IN THE PROTEOMICS REVOLUTION
OLDEST HUMAN PROTEIN SEQUENCE
he oldest human fossil to have its protein sequenced is 800,000 years old - nearly twice the age of the oldest fossil to have its DNA sequenced. In April 2020, researchers at the University of Copenhagen in Denmark announced that they that once lived in Atapuerca, Spain. When the amino acids in the tooth enamel’s proteins were compared with sequences from other hominins, it showed that is a close relative of the last common ancestor of modern humans, Neanderthals and Denisovans. The oldest human DNA sequenced is from the 430,000-year-old fossilised teeth and bones of early Neanderthals.
