Before we wear ourselves out arguing about this point, what exactly does the author of the article mean when he says that the chimpanzee genome is 10% bigger than the human geonome? Number of chromosomes? Number of DNA pairs? Number of “genes” (i.e. DNA groupings which appear to effect phenotype).
And on the other hand, what exactly does a geneticist mean when he says that the genomes of two species are 50% or 95% or 99% identical? Or 50% or 5% or 1% different?
The fact which I consider more interesting is that there is much greater variation among individuals within the chimpanzee genome than there is among individuals within the human genome, not withstanding the enormously larger numbers and geographic distribution of the human population.
If variation within the genome is propotional to the age of the species, then Chimps have been around a lot longer than humans.
It appears you got my point.
