I did not actually hear them talking but I knew they were because they were very quiet when I entered the room

.
I like the theory rather idea.. as it has made no predictions and remains unsupported by by experiment..that we owe our power of speech to dogs

.
It goes this way ..having dogs around in our early days when we lived in caves as they say, the fact that we did not need to develope the sence of smell, they took care of that for us, it allowed room in our brains to develope the software for speech

.
The neanderthals on the other hand being cat lovers, i figure

, took up the area in their brain they could have used for speech to develop a keen sence for smell.
We got the advantage over them because of the dog and presumably we were able to eliminate them from the huminiod contest

.. I like the idea

.
I dont like the idea put forward by cat lovers that dogs have masters and cats have staff however

and prefer this..you feed a dog and he thinks... my master feeds me he must be God whereas the cat when fed thinks wow he feeds me I must be God

. No doubt the dog is correct and the cat full of itself.
Hope hearing these oldies brings a smile to your day.
