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.
They are thought to be those of a female human and have been dated to approximately 117,000 years ago. This makes them the oldest known footprints of an anatomically modern human . The estimated age of Eve's footprint means that the individual who left the tracks in the soil, thought to be female, would have lived within the current wide range ...
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.
Researchers say the discovery proves the theory that some ancient human ancestors were neighbors Discovery of 1.5 million-year-old footprints shows two different human ancestors lived alongside ...
Early research using molecular clock methods was done during the late 1970s to early 1980s. Allan Wilson, Mark Stoneking, Rebecca L. Cann and Wesley Brown found that mutation in human mtDNA was unexpectedly fast, at 0.02 substitution per base (1%) in a million years, which is 5–10 times faster than in nuclear DNA. [8]
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.
