Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain extinction and its causes, report conservation status from authoritative sources, describe mass extinctions, and support conservation action without alarmism or dismissal.

The dying out of a species, subspecies or population so that no living members remain, either globally or locally, occurring through natural processes and, at accelerated rates, through human activity; mass extinction events have punctuated Earth history, and current biodiversity loss is assessed by bodies such as the IUCN and IPBES.

What it is for: Understanding biodiversity loss and conservation.

It can be check whether a species is extinct or threatened; explain causes of extinction; describe mass extinction events; find conservation actions and organisations.

Distinguishing features

No living members remain

Global or local

Natural and human-driven

Assessed by authorities

What it looks like

Not physical; the absence of a species, documented in records.

How it is recognised

Declared by conservation bodies after searches

Local extinction differs from global

Extinct in the wild means survival only in captivity

  • How should de-extinction debates be attributed?
