AI Insight
Research using amber fossils has revealed that an ancient landmass that separated from northwestern Australia approximately 150 million years ago carried plant and animal life northward over 100 million years of drift. This traveling landmass ultimately collided with Southeast Asia and contributed biological diversity that helped establish the region's exceptionally rich tropical forests. The findings provide new evidence for how geological processes shaped the distribution of species in one of Earth's most biodiverse regions.
Why it matters
This discovery enhances understanding of how plate tectonics and continental drift have influenced the evolution and distribution of tropical biodiversity. The research helps explain why Southeast Asia hosts such extraordinary species richness and provides insights into long-term biogeographical processes that shape modern ecosystems.
Understand the Science
A landmass that broke away from northwestern Australia about 150 million years ago and drifted north for the next 100 million years helped lay the foundations for Southeast Asia’s extraordinarily diverse tropical forests, new research has revealed.
