Who believes that? It beggars belief that there would be evolutionary pressure to develop the machinery for speech if intermediate steps were not being put to

Who believes that? It beggars belief that there would be evolutionary pressure to develop the machinery for speech if intermediate steps were not being put to progressively better uses.
- lucideer 8y agoThis depends on your definition of speech I guess. Many animals have vocal capabilities to create complex enough sounds that they could conceivably construct perceptible human phonetics (not least parrots), but they don't do so naturally in the wild. They do however all communicate with each other in some form, much of it vocal; does that constitute "speech"?
