[113] [114] Debate on megafaunal extinction in Australia has historically centred on whether the extinctions were caused by humans (which most sources estimate arrived in Australia at least 50,000 years ago, spreading to Tasmania later around 42-41,000 years ago [115]), or whether many megafauna species had already gone extinct prior to human ...
The O‘ahu ‘ō‘ō (Moho apicalis) is among dozens of bird species that became extinct after the human settlement of Hawaii. This is a list of Hawaiian animal 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 ...
During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
Relatively little is known about these extinct birds. The species became extinct from a large range of problems, including mosquito-transmitted diseases (which caused the species to retreat to higher ground, ultimately retreating to high-altitude montane forests in the Alakaʻi Wilderness Preserve ), introduction of mammalian predators, and ...

Mar. 1—Coby Torda still walks his dogs and works out at the gym just as he did before he became one of Hawaii's first confirmed cases of COVID-19, but not without a portable oxygen concentrator.
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 ...
