I heard of an interesting view that our species developed speech because we had the dog

.
The part of our brain we use for speech is the part the Neandathals had to use for their sence of smell...In the wild you need all the sences you can muster and the sence of smell is perhaps as important as the ability to see or to hear... they had no dog so never had room in their brain to develope the power of speech.
We did not need to be able to smell out dangerous things as we had our little friend...mans best friend in fact..the dog...who took over that task so as to release part of our brain our next stage of development...speech.
So we beat the Neandathals.. wiped them out I bet ... we could discuss their weaknesses and sleep at night not worrying they would creep up upon us..as our little friends would tell us if we needed to be awake.
Without speech where would we be... and because we had speech we needed the telephone which enabled the net to become a reality.
So pat your dog and thank him for giving us the power to rule the world
