Apes may be closer to speaking than many scientists think
Someone thought that apes couldn't control their breathing well enough to vocalize?  Really?  All mammals have pretty advanced control over their airways, otherwise we would be constantly inhaling nasty things.  Carnivores need control to sniff (see wolves) and herbivores need to hold their breath to be quiet enough to hear the wolves (see deer).<p>I'm about ready to say that all animal and human science from the 30s through the 50s should be tossed.  From all birds mating for life, belly-dragging dinos, to apes that cannot hold their breath ... were they just making stuff up?
