The Lower Paleolithic period lasted over 3 million years, during which there many human-like species evolved including toward the end of this period, Homo sapiens.The original divergence between humans and chimpanzees occurred 13 (), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being ...

The passenger pigeon, one of the hundreds of species of extinct birds, was hunted to extinction over the course of a few decades. As long as species have been evolving, species have been going extinct. It is estimated that over 99.9% of all species that ever lived are extinct.
The following list is incomplete by necessity, since the majority of extinctions are thought to be undocumented, and for many others there isn't a definitive, widely accepted last, or most recent record. According to the species-area theory, the present rate of extinction may be up to 140,000 species per year. [1]
Most likely underwater volcanism associated with the Caribbean large igneous province, which would have caused global warming and acidic oceans [14] Aptian extinction: 117 Ma: Unknown, but may be due to volcanism of the Rajmahal Traps [15] Jurassic: End-Jurassic (Tithonian) 145 Ma
A species is declared extinct after exhaustive surveys of all potential habitats eliminate all reasonable doubt that the last individual of a species, whether in the wild or in captivity, has died. [15] Recently extinct species are defined by the IUCN as becoming extinct after 1500 CE. [1]
For example, there is approximately one extinction estimated per million species years. [7] From a purely mathematical standpoint this means that if there are a million species on the planet earth, one would go extinct every year, while if there was only one species it would go extinct in one million years, etc.
As of 2022, the International Union for Conservation of Nature (IUCN) listed 40 animal species as extinct in the wild. [1] That is approximately 0.04% of all evaluated animal species. The IUCN also lists five animal subspecies as extinct in the wild. This is a complete list of wild animal species and subspecies listed as extinct by the IUCN.
