Evolution Quote by Rick Hanson
““Brain Life began around 3.5 billion years ago. Multicelled creatures first appeared about 650 million years ago. (When you get a cold, remember that microbes had nearly a three-billion-year head-start!) By the time the earliest jellyfish arose about 600 million years ago, animals had grown complex enough that their sensory and motor systems needed to communicate with each other; thus the beginnings of neural tissue. As animals evolved, so did their nervous systems, which slowly developed a central headquarters in the form of a brain.””
