Many years ago I crossed the Lombok straight in a dugout. Sounds exciting and dangerous? Yes it was as sinkings were common back then. I was stunned on arrival that the environment was so different to Bali where I started. On return home (pre internet) I searched the library and found I had crossed the Wallace Line. What a brilliant mind.
As I recall Aldous Huxley's grand father (and father?) were early supporters and researchers of the evolution theory. More great minds in an era of great break throughs.
