Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

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 list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage. For the earlier history of the human lineage, see Timeline of human evolution#Hominidae , Hominidae#Phylogeny .
Before Homo sapiens, Homo erectus had already spread throughout Africa and non-Arctic Eurasia by about one million years ago. The oldest known evidence for anatomically modern humans (as of 2017) are fossils found at Jebel Irhoud, Morocco, dated about 360,000 years old.
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to mammals — fills a longstanding gap in the fossil record.

Her fossils were also found near animal remains which indicated that she inhabited a forest type of environment, contrary to the theory that bipedalism originated in savannahs. [7] Ardi was not the first fossil of A. ramidus to come to light. The first ones were found in Ethiopia in 1992, but it took 17 years to assess their significance. [5]
