Anatomically modern humans appear in Africa. [103] [104] [105] Around 50 ka they start colonising the other continents, replacing Neanderthals in Europe and other hominins in Asia. 70 ka Genetic bottleneck in humans (Toba catastrophe theory). 40 ka Last giant monitor lizards (Varanus priscus) die out. 35-25 ka Extinction of Neanderthals.

The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The hyperdisease hypothesis proposes that humans or animals traveling with them (e.g., chickens or domestic dogs) introduced one or more highly virulent diseases into vulnerable populations of native mammals, eventually causing extinctions. The extinction was biased toward larger-sized species because smaller species have greater resilience ...
Prehistoric animals of the Pleistocene epoch, existing between 2.58 million and 11.7 thousand years ago, during the early Quaternary Period of the Cenozoic Era See also the preceding Category:Pliocene animals
Paleontologists are revealing early humans actually co-existed with a human-like species some 300,00 years ago. The cousin of homo sapiens, called homo naledi, was discovered in 2013 in a cave ...
The animal’s fossil records date back 225 million years, predating the previously confirmed first mammal by approximately 20 million years. Earliest known mammal identified using fossil tooth ...
However an epizootic outbreak in 1919 reduced the animals to just 50, and the last individuals were poached in 1927. [62] The only captive animal, a male, lived in Germany between 1908 and 1925 and bred with females of the lowland wisent subspecies. As a result, several wisent populations carry its genes today.
