Over time, means through which creatures have communicated with each other have evolved. From this, we now have words that supposedly carry meaning with them through which we are able to express our ideas and feelings to other.

Science attempted to answer this by tracing our ancestry through our mammalian brothers all the way back to the pre-biotic soup we emerged from. Religion explained it using the Garden of Eden and the creation of man in God's image.
Whitehead had his own ideas about these issues just like all of us. As far as evolution, he essentially came up an alternative to scientific materialism, what he called a new doctrine of organism. Basically, everything in this world started out as 'stuff'.
