Bioscience:The Endless Voyage — Survivors
The deep sea is the largest living space on Earth. It's home to the largest animal communities on Earth， largest in terms of aerial extent， largest in terms of biomass， largest in terms of numbers of individuals. When we look at the organisms that live on the present land and sea， we're looking at groups that have evolved since that last big extinction. If you look at something that's advanced in terms of survival abilities， you might look at the insects and say， "Boy， they are very advanced".
