Human Success

Humans have been a very successful species in terms of the number of individuals living on the earth at this time. We can exchange information outside of DNA. Animals must rely upon what is built into their system, primarily instincts, for their information about how to deal with their environment. People can talk to each other about their environment. For example, I can tell you not to eat the leaves of a cherry tree, because they are poisonous, thereby saving your life.
