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 ...
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, [109] [110] is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
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]
This is a list of Antillian and Bermudan animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [a] and continues to the present day. [1] This list includes the Antilles archipelago and the Bermuda Islands, collectively known as the West Indies.
However, a few species have disappeared from Africa as part of the ongoing Holocene extinction, driven by human activity. Madagascar and the Indian Ocean islands, Macaronesia, and Saint Helena, Ascension and Tristan da Cunha are biogeographically distinct from mainland Africa and have a much greater number of Holocene extinctions. Recently ...
Holocene extinctions, biological taxa that went extinct during the current geological/paleobiological Holocene epoch of the Quaternary Period. Extinct plant/flora and animal/fauna species of the last 12,000 years (occurring from ~10,000 BCE to the present day.
The Holocene extinction event is currently under way. [12] Factors in mass extinctions include continental drift, changes in atmospheric and marine chemistry, volcanism and other aspects of mountain formation, changes in glaciation, changes in sea level, and impact events. [10]
This is a list of European species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] This list includes the European continent and its surrounding islands.
