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.
The last common ancestor between humans and other apes possibly had a similar method of locomotion. 12-8 Ma The clade currently represented by humans and the genus Pan (chimpanzees and bonobos) splits from the ancestors of the gorillas between c. 12 to 8 Ma. [31] 8-6 Ma Sahelanthropus tchadensis
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.
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 ...
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.

Another baby girl, between 12 and 16 months old, was found buried in a section of yard belonging to a home on the island of Aegina, Greece, and lived between 1398 and 1221 B.C., the study said.
Its genetic material was most likely DNA, [15] so that it lived after the RNA world. [a] [18] The DNA was kept double-stranded by an enzyme, DNA polymerase, which recognises the structure and directionality of DNA. [19] The integrity of the DNA was maintained by a group of repair enzymes including DNA topoisomerase. [20]
