Spectator letters: America as a genetic experiment, and a gypsy reply to Rod Liddle
The American experiment Sir: One can test Nicholas Wade’s hypothesis that social and political life is genetically determined (‘The genome of history’, 17 May) by constituting a nation along European lines, admitting immigrants from all over the world, and measuring the extent to which these immigrants assimilate to the dominant culture.

Cultural inheritance therefore outweighs genetic inheritance in the political sphere, and historians may rest easy. Dr James McEvoy Centre for Biomedical Sciences, Royal
