Dean Hamer has both done the research and written the books on personality genetics and the search for genetic markers that correlate with personality differences. His book, with Peter Copeland, is Living with our genes (Doubleday, 1998).

The story of homeotic genes and the way in which they have opened up the study of embryology is told in two recent textbooks: Principles of development by Lewis Wolpert (with Rosa Beddington, Jeremy Brockes, Thomas Jessell, Peter Lawrence and Elliot Meyerowitz) (Oxford University Press, 1998), and Cells, embryos and evolution by John Gerhart and Marc Kirschner (

Blackwell, 1997).

The geography of genes is explored in Luigi Luca Cavalli-Sforza and Fran-cesco Cavalli-Sforza's The great human diasporas (Addison Wesley, 1995); some of the same material is also covered in Jared Diamond's Guns, germs and steel (Jonathan Cape, 1997).

2. Intriguingly, the genetic evidence generally points to a far more rapid migration rate for women's genes than men's (comparing maternally inherited mitochondria with paternally inherited Y chromosomes) — perhaps eight times as high. This is partly because in human beings, as in other apes, it is generally females that leave, or are abducted from, their native group when they mate.
