No, the aren't exaggerated.<quoted text>
We are less than 96% chimpanzee, those stats are exaggerated, child!
"The difference between chimpanzees and humans due to single-nucleotide substitutions averages 1.23 percent, of which 1.06 percent or less is due to fixed divergence, and the rest being a result of polymorphism within chimp populations and within human populations. Insertion and deletion (indel) events account for another approximately 3 percent difference between chimp and human sequences, but each indel typically involves multiple nucleotides. The number of genetic changes from indels is a fraction of the number of single-nucleotide substitutions (roughly 5 million compared with roughly 35 million).
So describing humans and chimpanzees as 98 to 99 percent identical is entirely appropriate (Chimpanzee Sequencing 2005).
The difference measurement depends on what you are measuring. If you measure the number of proteins for which the entire protein is identical in the two species, humans and chimpanzees are 29 percent identical (Chimpanzee Sequencing 2005).
If you measure nonsynonymous base pair differences within protein coding regions, humans and chimps are 99.75 percent identical (Chimpanzee Sequencing 2005, fig. 9).
The original 98.4 percent estimate came from DNA hybridization experiments, which measured (indirectly, via DNA melting temperature) sequence difference among short segments of the genomes that are similar enough to hybridize but with repetitive elements removed (Sibley and Ahlquist 1987).
Whatever measure is used, however, as long as the same measurement is used consistently, will show that humans are more closely related to chimpanzees (including the bonobo, sister species to the common chimpanzee) than to any other species."
