It is way higher than that. 98% with chimps. Heck, we share a good number
of genes with *bacteria.*
But that is not the point. Evolution is working on the differences, not
the common elements. And brothers have half of the differences in common,
or a little more since their Y chromosomes are identical (barring mutation).
Read Dawkins on this point. He explains it clearly.
