Found a very interesting para in the Review section of UK Sunday Telegraph, 22nd March It is all about Genes. Article written by Robert Matthews. It says ' Marc Feldman, at Stanford California, is one of a growing number of theoretical biologists now using "gene-culture" theory to study evolutionary conundrums beyond the reach of gene-centred Darwinism. For example, one long- standing puzzle concerns the fact that most humans are genetically incapable of digesting milk. Yet, in countries such as England, with long histories of dairy farming, studies show that 90% of the people possess the necessary genes - over four times the level in non-dairy regions. Feldman and his colleagues have shown that this powerful clustering effect cannot be explained solely by Darwinian selection of "favourable" genes. It requires the extra influence of cultural pressure, with children in dairy regions being more likely to "inherit" the use of milk as a key source of nutrition from their parents. By taking into account both forms of inheritance, Feldman and his colleagues have been able to explain, with mathematical precision, the details of milk intolerance among humans.
