Using advanced simulations of the planet's future, experts have estimated that in 250 million years, all landmasses will collide to form a supercontinent known as Pangea Ultima.

The consequences of these trends could entail the extinction of numerous species and render large parts of the planet uninhabitable.Although Farnsworth suggested some mammalian species may survive on the fringes of Pangea Ultima, it's highly likely that mammals' dominance on Earth, which has persisted for the past 65 million years, would come to an end.

Scientists Forecast Most Mammals Will Go Extinct in 250 Million Years as Earth Warms
Using advanced simulations of the planet's future, experts have estimated that in 250 million years, all landmasses will collide to form a supercontinent known as Pangea Ultima, leading to catastrophic warming and potentially driving mammals, including humans, to extinction.
Newly-published findings have revealed that scientists are forecasting mammals have just 250 million years left on Earth before the next extinction.

Cold-blooded reptiles could potentially take their place as the dominant life forms in this scorching future.
While the study has sparked debate, with some experts suggesting factors like the decline in heat escaping from Earth's interior might alter the timeline, it offers valuable insights for the future of our planet.
Furthermore, insiders say it may serve as a reference for scientists studying other planets to determine what forms of life could survive in distant solar systems.
The findings were published in
Nature Geoscience journal.
