In practice, the history of that most racially mixed country of all, the United States, supports this idea. When integration has been encouraged, as with the descendants of the great flood of European immigrants in the late 19th and early 20th centuries, ethnic distinctions have vanished. When integration has been discouraged, as with the descendants of slaves liberated shortly before those European immigrants arrived, differences have been sharpened. Even in Britain, official policy seems to be shifting from 'multiculturalism', which celebrated diversity and thus encouraged distinction, to a deliberate attempt to forge a cultural consensus.
What the brand theory of ethnicity does not require, however, is that minorities submit to the majority's definition of what the brands should be. All that is needed is for each generation to be encouraged to form its own identity from the widest range of materials possible.
Darwinian analysis thus sheds light on a number of pressing questions. There are others. The rise of metabolic syndrome (obesity plus high blood-pressure equals diabetes plus heart disease) seems to Darwinists the consequence of people trying to sate appetites for sugar and fat that evolution put no brakes on because they were so rare in the natural world.

Pretending young adults are children so that they can be educated en masse in schools is another area ripe for investigation. And the refusal of people to adhere to the patterns of behaviour prescribed for them by classical economics has already spun off a field called behavioural economics that often has Darwinian thinking at its roots.
No one is suggesting Darwinism has all the answers to social questions. Indeed, with some, such as the role of hierarchies, it suggests there is no definitive answer at allitself an important conclusion. What is extraordinary, though, is how rarely an evolutionary analysis is part of the process of policymaking. To draw an analogy, it is like trying to fix a car without properly understanding how it works: not impossible, but as likely as not to result in a breakdown or a crash. Perhaps, after a century and a half, it is time not just to recognise but also to understand that human beings are evolved creatures. To know thyself is, after all, the beginning of wisdom.
