The genomes of living animals are littered with DNA from long-gone relatives, providing a lens on evolution, past extinctions, and perhaps even solutions to agricultural problems.
A remaining challenge in the study of human accelerated regions (HARs) is establishing their specific functions during development and other biological processes.
Re-examination of a thigh bone from one of the earliest putative hominins could impact scientists’ understanding of the origins of human bipedalism, a study suggests.
Unlike human brains, chimpanzee brains don’t get smaller as they age, suggesting that pronounced neurological decline is a uniquely human byproduct of our oversized brains and extreme longevity.
