Apes to Humans .
Mans bipedalism (ability to walk upright ) requires a more precise balancing mechanism than creatures that go on all fours . Fossil men and apes can be distinguished by examining the labyrinth , a hard bony structure of the inner ear that is preserved during fossilisation . Professor Bernard Wood of University of Liverpool did computerised tomography scans of inner ears of fossil apes and man . Man , who is bipedal , has a more complex pattern of the labyrinth than Knuckle walking apes . Man requires a more sophisticated balancing mechanism . There are no intermediate patterns .

Among the fossil hominids , the earliest to demonstrate the modern human morphology is Homo Erectus . In contrast the semi circular dimensions in crania from Southern Africa attributed to Australopithecus and Paranthropus resemble those of ...the extinct great apes .

Spanish and American researches used CT scans to measure the bones and spaces in the outer and middle ears of five specimens , thought to be Homo heidelbergensis. They then worked out how well the hearing apparatus they found could respond to various frequencies . Like modern humans the hominids ears would have been sensitive to frequencies in the range from 2 to 4 kilohertz , suggesting that they too could distinguish the sounds of speech . Chimpanzees ears are relatively insensitive at those frequencies .

Not only are chimps not in the same league as men and women when it comes to converstation , but their sense of musical harmony leaves much to be desired :

Monkeys do not prefer sounds that are harmonious to human ears . Suggesting that people have a unique appreciation of music . Even young infants enjoy hearing consonant intervals more , suggesting that PEOPLE ARE HARD WIRED WITH THE PREFERENCE AT BIRTH .
New Scientist 25 September 2004 page 17 . 

"Fossil evidence of human evolutionary history is fragmentary and open to various interpretations . Fossil evidence of chimpanzee evolution is ABSENT ALTOGETHER."
