There's a scale at which time stops making instinctive sense. What we call "ancient" civilizations existed just a few thousand years ago. The oldest piece of DNA that's been sequenced is 700,000 years old. The earliest remains of humans outside of Africa are dated to 1.7 million years in the past; the hominins who preceded humans were walking upright 6 million years ago.
Scientists have identified fossil proteins in a 3.8 million year-old ostrich eggshell, suggesting that proteins could provide valuable new insights into the evolutionary tree, much further back in time than was previously thought.
In 1960, Jonathan Leakey, the oldest son of the paleoanthropologists Mary and Louis Leakey, discovered the partial skull of an ancient primate in Tanzania’s fossil-rich Olduvai Gorge. The skull, dated to about 1.8 million years old,...
Scientists have examined fossilized ostrich eggshells from fossil localities in Africa to search for proteins, and more importantly are seeking to understand what exactly can save these molecules from the ravages of time.
Scientists from the Universities of Sheffield, York and Copenhagen have identified fossil proteins in a 3.8 million year-old ostrich eggshell, suggesting that proteins could provide valuable new insights into the evolutionary tree, ...
