More than sixty years after the death of Hitler, the defeat of Nazism, and the horrors of the Holocaust, the concept of a Jewish race is still alive and well in the minds of too many. This book is an attempt to destroy such a concept from both a biological and historical point of view. To be a race Jews would have to have been isolated from other populations. However, they never avoided crossbreeding and converted many non-Jews. In other words, from Day One Jews have married non-Jews, and therefore there is no way to genetically characterize them as a race. Nevertheless, many people find it difficult to accept the ideas that Judaism is not hereditary, but a religion, and that Jews who abandon the Jewish faith, whether they adopt another religion or none at all, are no longer Jews.
