The chimpanzee–human divergence likely took place around 10 to 7 million years ago. [1] 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.
Examples of Clovis and other Paleoindian point forms, markers of archaeological cultures in North America. The Solutrean hypothesis on the peopling of the Americas is the claim that the earliest human migration to the Americas began from Europe during the Solutrean Period, with Europeans traveling along pack ice in the Atlantic Ocean.
Artist's conception of Pleistocene Vero Man hunters and two Arctodus cave bears. Vero Man refers to a set of fossilized human bones found near Vero (now Vero Beach), Florida, in 1915 and 1916. The human bones were found in association with those of Pleistocene animals. Pleistocene dates range from 2,580,000 to 11,700 years ago.
The dorsal pair of ribs form a rib cage to support the lungs, while the ventral pair disappears. Ichthyostega is another extinct tetrapod. Being one of the first animals with only two pairs of limbs (also unique since they end in digits and have bones), Ichthyostega is seen as an intermediate between a fish and an amphibian.
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
Most dogs form a sister group to the remains of a Late Pleistocene wolf found in the Kessleroch cave near Thayngen in the canton of Schaffhausen, Switzerland, which dates to 14,500 years ago. The most recent common ancestor of both is estimated to be from 32,100 years ago. [ 29 ]
Leidy also mistakenly believed the fossils were from the Pliocene, but they actually come from the Pleistocene. [3] Footprints preserved within Blue Spring Cave. Later in 1919, Oliver Perry Hay described a left canine from Vero, Florida that he named Felis veronis, though it is now seen as a synonym of P. onca augusta. [3]
The Sicilian European Stage is a European faunal stage in the Pleistocene of the Geologic time scale.While earlier defined as between 0.781 ± 0.005 Ma and 0.26 Ma (million years ago), in the middle of the Pleistocene epoch, more accurate data places it at the end of the early Pleistocene, ending at 0.781 ± 0.005 Ma, and makes it a sub-stage.
