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 ...
[82] [83] This is supported by a date of 50,000–60,000 years ago for the oldest evidence of settlement in Australia, [71] [84] around 40,000 years ago for the oldest human remains, [71] the earliest humans artifacts which are at least 65,000 years old [85] and the extinction of the Australian megafauna by humans between 46,000 and 15,000 ...
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.
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
A growing number of scientists believe a sixth mass extinction event of a magnitude equal to the prior five has been unfolding for the past 10,000 years as humans have made their mark around the ...
[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 ...
