As far as I’m concerned - The more we have come to understand genetics, the less acceptance any scientific basis for race.

Shirley Tilghman director of Integrative Genomics at Princeton at a part of the Human Genome project:

“From a scientific perspective there is no such thing as race. You cannot scientifically distinguish a race of people genetically from a different race of people. Now you can find a gene that affects skin color, and you can show that this gene has one form in people of African descent and is different form of people, let’s say , of Danish descent. But that’s just one little change. That doesn’t make them a race. If you look at all the other things in their DNA that determine all the ways in which we’re the same, in fact the two DNAs are indistinguishable.”

The American Anthropological Association statement on race:

“With the vast expansion of scientific knowledge in this century, however, it has become clear that human populations are not unambiguous, clearly demarcated, biologically distinct groups. Evidence from the analysis of genetics (e.g., DNA) indicates that most physical variation, about 94%, lies within so-called racial groups. Conventional geographic “racial” groupings differ from one another only in about 6% of their genes.”

J. Craig Venter, head of Celera Genomics Corporation (and one of the most important figures in the Human Genome project).

“In my view one of the most important outcomes from our sequencing of the human genetic code is clear support for the notion that race is a social concept not a scientific one. We sequenced the genomes of 5 individuals, 3 females and 2 males of self-identified ethnicity as Chinese, Hispanic, African-American or Caucasian. Looking at the genetic code we can tell who is male and who is female but we cannot determine who is Chinese, Hispanic, African-American or Caucasian.”

National Institutes of Health:

“Separation of the human race into ethnic or population divisions is really not scientifically justifiable.”

Those most involved with the Human Genome project all agree, there is no scientific basis for race.

“Race” as popularly defined is based on stupid criteria such as skin colour, eye colour or facial structure and it’s pointless to debate that anyway. The entire reason race isn’t considered scientifically valid is because there are far too many cross overs (such as blood type).
