So what should we make of the concept of race?
There are a lot of anthropologists who would say we should just throw this concept away
completely.
There's no basis for it.
And those people are responding to what many scholars call essentialist notions of race.
There's something about this particular group of people, perhaps about their anatomy
or their physiology or their brains or their genes or something like this, that differentiates
them from various other groups of people.
If there's one thing that we've learned from biological science and psychological
science over the last century it's that there's an enormous amount of variation
within the groups that we've traditionally thought of as races, far more than there is
between the groups we've traditionally thought of as races.
It turns out that if you look at things from a genetic point of view the certain kinds
of molecular sequences are more common in some groups than in other groups.
That's because during the course of human history these groups have been separated from
one another.
They haven't intermarried and that's given various chances for various kinds of genetic
material to become prevalent in some groups but not in others.
But the first thing to say about that is that these differences are trivial!
Largely trivial; there are some cases, such as well known diseases that tend to affect
some groups more than others, that is not trivial for the sufferers.
But by and large these differences are perfectly trivial.
Now about 15 years ago a tremendously brilliant study was done by researchers at Stanford
that actually divided the human population into groups that the researchers themselves
called interbreeding populations.
They didn't want to call them races but very quickly the popular press picked this
up and started referring to them as races.
So you might start out with the human population and ask the following question: on the basis
of biological evidence, gene frequencies, molecular frequencies of DNA sequences in
different populations, what would you get if you wanted to divide the population into
two?
Well you'd get actually Africans and most Asians, central and western Asia, and Europeans
as forming one group, and the rest of the human populations forming another group.
Now what would happen if you did it into three groups?
Well then you'd get the Africans separated out from the Eurasian population.
What would happen if you did it for four groups?
Five groups?
Six groups?
Seven groups?
Eight groups?
Nine groups?
The first five or so of these give you something like sort of standard racial groups with a
few odd little twists.
The sixth gives you—as there's sixth of these groups—gives you a tiny little population
that has been isolated because of mountain barriers in Asia.
Now those are genuine divisions that have come out of our human history and that are
still present in the DNA sequences of the genomes of various people.
But whether we want to draw any distinctions at all within the human population is completely
up to us.
Remember how I did this: I said 'If you want to divide the human population into two, to
three, to four, to five, to six, to seven, this biology will tell you how to make the
biologically significant decisions.'
But why should we want to do that?
Is there a point in doing that?
Well sometimes there is a point.
Sometimes there's a point in recognizing that certain people are more closely related
to other people, if you want to do medical transplantation, for example.
There is a point in saying, well what you need is somebody to give you a kidney who
comes from this particular group.
But there are other people who say this is just the sort of stuff that breeds discrimination
and prejudice as it has in the past, and there are yet other people who say precisely because
of that discrimination that we've had in the past it's important to acknowledge these
groups.
So I want to say there's a certain kind of biological phenomenon that stands behind
the historic process of dividing people into racial groups.
But actually these racial groups are constructed by us.
It's we who decide that we want to draw the lines and the basis on which we should
decide that is an ethical basis.
We should decide how we actually treat people most fairly.
So the issue is really not whether there are racial groups.
I mean we could think about racial groups as one, two, three, four, five, six, seven
and so on, in divisions in this initial human population.
But it's a question of what divisions, if any, are useful from the point of view of
justice and fairness.
And that I think is the right way to think about race.
So is it scientific?
Well there's sort of something scientific lurking in the background.
Is it socially constructed?
Yes, it's socially constructed.
And the social construction ought to proceed on the best ethical basis we can find.
