Scientists who compared the food preferences of identical and fraternal twins found that some tastes are inherited while others are acquired. "This is the first study to include significant numbers of protein foods and the first to show a high heritability for these," said Professor Jane Wardle of the charity Cancer Research...

LONDON, Ontario -- A paper showing a strong genetic contribution to patriotism and in-group loyalty was published in the October issue of Nations and Nationalism, 11, 489-507, entitled "Ethnic nationalism, evolutionary psychology, and genetic similarity theory." Co-ethnics are as similar to each other as half-siblings when compared to all the genetic variation in the world. Two-random English people are the equivalent of 1/32 cousin by comparison with Germans; 3/8 cousin by comparison with...
