Tectonic shifts can pave the way for explosions of life by altering sea levels.
Every 36 million years, the planet’s marine ecosystems experience surges in biodiversity. New research has discovered the cycle is indirectly triggered by geological changes led by plate tectonics influencing sea levels, paving the way for new life to thrive.
When continents dry up and then flood again, barren stretches of land can become extensive shallow seas that are a playground for biodiversity. The change opens up new ecological niches, driving explosions of life as species evolve to be the fittest to fill the free real estate.
One way in which these periods of droughts and floods can occur comes with the shifting of Earth’s tectonic plates that force changes in sea levels. Researchers exploring the phenomenon now report they’ve identified a cycle of around 36 million years in which marine biodiversity explodes as an indirect consequence of tectonic activity.
