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.
Fossils have been visible and common throughout most of natural history, and so documented human interaction with them goes back as far as recorded history, or earlier. There are many examples of paleolithic stone knives in Europe, with fossil echinoderms set precisely at the hand grip, dating back to Homo heidelbergensis and Neanderthals . [ 15 ]
Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, "zone fossil", is used when the fossil has all the characters stated above except wide geographical distribution; thus, they correlate the surrounding rock to a biozone rather than a specific time period.
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
People first uncovered fossils around San Pedro High School in 1936. They were ancient shells belonging to snails and other mollusks from tens of thousands of years ago.
The Plesiadapiformes very likely contain the ancestor species of all primates. [24] They first appeared in the fossil record around 66 million years ago, soon after the Cretaceous–Paleogene extinction event that eliminated about three-quarters of plant and animal species on Earth, including most dinosaurs. [25] [26]
The fossils have perplexed scientists ever since. But a new revelation sheds more light on how the diminutive human — nicknamed hobbit after J.R.R. Tolkien’s fictional characters — might ...
New research shows that Homo sapiens traveled from Africa to East Asia and toward Australia up to 86,000 years ago.
