Part 4/9:
Standing at the crossroads of evolution theorized by both Wallace and Charles Darwin, the modern expedition aims to trace the evolution of marine species across the Wallace Line and determine if underwater geological features contribute to species separation.
Underneath the Surface: Collecting Data
As the expedition team launches into the depths of Wallace’s imaginary boundary, they anticipate a challenging dive marked by strong currents and extreme depths. Using advanced gas mixtures, they can spend more time exploring the underwater canyons that delineate the Wallace Line. High-speed currents carry nutrients and support a rich marine ecosystem, housing a myriad of predatory species like whitetip reef sharks.
