The oldest DNA sequenced from physical specimens are from mammoth molars in Siberia over 1 million years old. [6] In 2022, two-million-year-old genetic material was recovered from sediments in Greenland , and is currently considered the oldest DNA discovered so far.
Human trichromatic color vision had its genetic origins in this period. Catarrhines lost the vomeronasal organ (or possibly reduced it to vestigial status). Proconsul was an early genus of catarrhine primates. They had a mixture of Old World monkey and ape characteristics.
The oldest human skeletal remains are the 40ky old Lake Mungo remains in New South Wales, but human ornaments discovered at Devil's Lair in Western Australia have been dated to 48 kya and artifacts at Madjedbebe in Northern Territory are dated to at least 50 kya, and to 62.1 ± 2.9 ka in one 2017 study.

Human DNA recovered from remains found in Europe is revealing our species’ shared history with Neanderthals. The trove is the oldest Homo sapiens DNA ever documented, scientists say.
Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. “The study opens the door into a past that has basically ...
Commencement of plate tectonics with old marine crust dense enough to subduct. [28] 2023 Ma Formation of the Vredefort impact structure, one of the largest and oldest verified impact structures on Earth. The crater is estimated to have been between 170–300 kilometres (110–190 mi) across when it first formed.
A uniquely preserved prehistoric mudhole could hold the oldest-ever human footprints on the Arabian Peninsula, scientists say. The seven footprints, found amidst a clutter of hundreds of ...
The ID between humans and gorillas was determined to be 1.09, that between humans and chimpanzees was determined as 1.14. However the distance to six different Old World monkeys was on average 2.46, indicating that the African apes are more closely related to humans than to monkeys.
