"Revealing the 36-Million-Year Geological Cycle Fueling Explosive Life on Earth"

Tectonic plates, the massive slabs of rock beneath Earth's surface, may drive bursts of marine biodiversity every 36 million years by causing sea levels to rise and fall. Fluctuating sea levels create new habitats for ocean life to thrive. The cyclical flooding and drying up of continents has been occurring for at least 250 million years. The study compared plate tectonic movements and sea-level changes with marine fossil records and found that tectonic changes correlated with highly biodiverse periods in the fossil record. This research suggests that global sea level change driven by Earth's geological processes has largely influenced the biodiversity of marine life throughout history. However, human-caused climate change is now contributing to a faster rise in sea levels, which could impact marine biodiversity.

"Groundbreaking Discovery: 36-Million-Year Geological Cycle Unleashes Explosions of Biodiversity"

Scientists have discovered that movements in Earth's tectonic plates indirectly stimulate bursts of biodiversity through 36-million-year cycles by causing sea levels to rise and fall. These cycles, which have been traced back 250 million years, significantly influence marine species diversity by altering shallow sea and shelf habitats. The fluctuations in water levels create breeding grounds for life, leading to the emergence of new species. This research challenges previous notions of species evolution and highlights the crucial role of tectonic cycles and global sea level changes in shaping the biodiversity of marine life over millions of years.

"Unveiling the 36-Million-Year Geological Cycle Fueling Biodiversity"

Scientists have discovered a 36-million-year geological cycle driven by movement in the Earth's tectonic plates, which indirectly triggers bursts of biodiversity by causing sea levels to rise and fall. These cycles of sea level changes have a significant impact on the diversity of marine species, with different habitats expanding and contracting as water levels fluctuate. By studying the fossil record, researchers have found that these shifts lead to bursts of new life. The findings challenge previous ideas about species changes over long periods and provide evidence that tectonic cycles and global sea level change have played a crucial role in shaping marine biodiversity over millions of years.
