AI overview

Extinction is when a species or group of organisms completely disappears and no longer exists anywhere on Earth, like the thylacine that died out in recent times or ancient creatures like Palaeotherium that we only know about through fossils. It matters because once a species goes extinct, it's gone forever, and the loss of different species changes ecosystems and reduces the diversity of life on our planet.

Extinction is the termination of a species via the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence.
