Why does an invisible line in the ocean separate two entirely different evolutionary worlds?
Explore the mystery of the Wallace Line—a deep-water trench running between Bali and Lombok that kept Asian and Australasian ecosystems completely isolated for over 50 million years. Despite being only 20 miles apart with identical climates, zero mammals crossed this divide due to a 4,000-foot abyss and brutal underwater currents between the Pacific and Indian Oceans.
Fast forward to today: humans casually cross this ancient evolutionary barrier on a simple $20 public ferry ride.
In this video, you'll discover:
• The mystery behind the Wallace Line and biogeography
• Why jungle birds and Ice Age beasts couldn't cross the Lombok Strait
• The terrifying underwater hydraulics separating the Pacific and Indian Oceans
