This category lists some of the species that have become extinct as a result of intentional or unintentional human activity. If a more specific reason is known, the species should also be assigned to a subcategory of Category:Species by threat. They may also need to be placed in Category:Extinctions since 1500.
There were some suggestions that phorusrhacids, like the majority of Pleistocene megafauna, were killed off by human activity such as hunting or habitat change. This idea is no longer considered valid, as improved dating on Titanis specimens show that the last phorusrhacids went extinct over one million years before humans arrived. [9]
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Aptian extinction: 117 Ma: Unknown, but may be due to volcanism of the Rajmahal Traps [15] Jurassic: End-Jurassic (Tithonian) 145 Ma: No longer regarded as a major extinction but rather a series of lesser events due to bolide impacts, eruptions of flood basalts, climate change and disruptions to oceanic systems [16] Pliensbachian-Toarcian ...
In fact, things are actually getting worse as the Earth undergoes a sixth mass extinction driven largely by human activity. Among those lost are a species of shark, 15 species of fish, and three ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Dr Alex Bond, senior curator in charge of birds at the Natural History Museum, has been part of the team tracing the fate of the curlew and said the extinction of bird species is “going to be ...
The extinction was biased toward larger-sized species because smaller species have greater resilience because of their life history traits (e.g., shorter gestation time, greater population sizes, etc.). Humans are thought to be the cause because other earlier immigrations of mammals into North America from Eurasia did not cause extinctions. [212]
