One of the first hypotheses regarding their symbolism was forwarded by French religious historian Salomon Reinach who supposed that, because only animals were depicted on cave walls, the images represented totem veneration, in which a group or a group member identifies with a certain animal associated with certain powers, and honours or ...
Neanderthal extinction occurred roughly 40,000 years ago with the immigration of modern humans (Cro-Magnons), but Neanderthals in Gibraltar may have persisted for thousands of years longer. The first recognised Neanderthal fossil, Neanderthal 1 , was discovered in 1856 in the Neander Valley , Germany.
As the possibility of extinction became more widely established in the sciences, so did the prospect of human extinction. [4] In the 19th century, human extinction became a popular topic in science (e.g., Thomas Robert Malthus's An Essay on the Principle of Population) and fiction (e.g., Jean-Baptiste Cousin de Grainville's The Last Man).
Map emphasising the Ebro River in northern Spain. The extinction of Neanderthals was part of the broader Late Pleistocene megafaunal extinction event. [1] Whatever the cause of their extinction, Neanderthals were replaced by modern humans, indicated by near full replacement of Middle Palaeolithic Mousterian stone technology with modern human Upper Palaeolithic Aurignacian stone technology ...
Beginning of animal evolution. [54] [55] 720–630 Ma Possible global glaciation [56] [57] which increased the atmospheric oxygen and decreased carbon dioxide, and was either caused by land plant evolution [58] or resulted in it. [59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
Most alarming is the state of the world’s migratory fish: Nearly all, 97%, of those listed are threatened with extinction. Migratory species include some of the most iconic animals on the planet ...
[47] [48] Brain expansion (enlargement) between 0.8 and 0.2 Ma may have occurred due to the extinction of most African megafauna (which made humans feed from smaller prey and plants, which required greater intelligence due to greater speed of the former and uncertainty about whether the latter were poisonous or not), extreme climate variability ...
