Re: "don't chimps and humans share 98% of their dna" Yes they do. But the EXPRESSION of those genes influences on development (like switches switched on and off at various stages of development in the life of any organism, genes code for protein expression) happens at different points in time, at different stages of fetal development and even into adult life. For just one example illustrating that, as Darwin himself noted many years ago (long before the modern science of genetics was even a glimmer) humans early in their fetal development, same as fish, etc., have gills. This is an example of genes' being expressed at one particular stage and then later "turned off". But humans actually have FEWER GENES than a plant... or even a nematode. (That is: functional genes that code for actual proteins.) So, with the mathematical variance between human DNA and our closest related modern species such as chimps, bonobos, being so small... the genetic variances between various peoples is obviously even more vanishingly small. (Hint: we all have the exact same three pigments expressed in our skin... merely in different proportions.)
