very interesting...how do we know the dolphins give each other names? sound recognition, as in identifying ecah other with a unique sound? Very interesting. I wonder why they do this? Maybe its cos they all look alike Please Register or Log in to view the hidden image! Re the lack of innate ability in humans I did not know this was due to rate at which they are born. maybe its due to adaptability as we are required to have a greater learning capacity in order to learn how to adapt to different environments. I would suggest that our innate abilities are lost due to language and taught knowledge but study of ferral kids would prove this theory wrong, meanwhile on subject of ferral kids, where did we learn our humanity from?
