About 250 million years ago, the Permian-Triassic mass extinction killed over 80 per cent of the planet's species. In the aftermath, scientists believe that life on earth was dominated by simple species for up to 10 million years before more complex ecosystems could evolve. Now this longstanding theory is being challenged by a team of international researchers – including scientists from McGill University and Université du Québec à Montréal.

A fossilized ocean ecosystem Until now, scientists have long theorized that scorching hot ocean conditions resulting from catastrophic climate change prevented the development of complex life after the mass extinction. This idea is based on geochemical evidence of ocean conditions at the time. Now the discovery of fossils dating back 250.8 million years near the Guizhou region of China suggests that complex ecosystems were present on Earth just one million years after the Permian-Triassic mass extinction, which is much earlier than previously thought

A million years may be nothing in geological terms but it’s astronomical in biological terms. Plenty of time for complex ecosystems to re-establish if even a fraction of a fraction of a fraction of a percent of complex life survived

So long as we have liquid water, life will spin up. It's a perfect medium for simple chemistry to coalesce, a critical point for formation.

In astronomical terms, 250 million years is 1.085 galactic years.

Life thrives upon the death of past generations not that surprising life rebounds quickly when given room and resources to explode

I wonder where humanity will be in 1 million years

Most likely not identifiable as human by modern standards.
