  1. What a brilliant video by PBS Eons! 😄👍 I never knew anything at all about the Wallace Line - never heard of it before. (Not even from Sir Attenborough...) I certainly take my hat off to all the scientists who help our understanding. And thanks for explaining the theory so clearly, EONS! Excellent. 🤗 M 🦘🏏😎
