The 3.48 Ga Dresser formation hosts microfossils of prokaryotic filaments in silica veins, the earliest fossil evidence of life on Earth, [70] but their origins may be volcanic. [ 71 ] 3.465-billion-year-old Australian Apex chert rocks may once have contained microorganisms , [ 72 ] [ 5 ] although the validity of these findings has been contested.
Archean stromatolites are the first direct fossil traces of life on Earth. The earliest identifiable fossils consist of stromatolites, which are microbial mats formed in shallow water by cyanobacteria. The earliest stromatolites are found in 3.48 billion-year-old sandstone discovered in Western Australia.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
The structures are considered to be one of the oldest ecosystems on Earth, according to NASA, representing the earliest fossil evidence for life on our planet from at least 3½ billion years ago.
Life on Earth may have begun even earlier than biologists suspected, at a time when the solar system was still in its infancy. Earth's oldest fossils yet discovered, give hope for life on Mars ...
The earliest known remains of Cro-Magnon-like humans are radiocarbon dated to 43,000–46,000 BP, found in Bulgaria, Italy, and Great Britain. [33] [34] Europe: Bulgaria: 46-44: Bacho Kiro cave: A tooth and six bone fragments are the earliest modern human remains yet found in Europe. [35] Europe: Italy: 45–44: Grotta del Cavallo, Apulia
Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
