Propagating Genes VS Memes
I have been a bit negative about memes, but they have their cheerful side as well. When we die there are two things we can leave behind us: genes and memes. We were built as gene machines, created to pass on our genes. But that aspect of us will be forgotten in three generations. Your child, even your grandchild, may bear a resemblance to you, perhaps in facial features, in a talent for music, in the colour of her hair. But as each generation passes, the contribution of your genes is halved. ...Our genes will only last in recognizable form for three generations or so, being halved with each generation; our memes, however, have the potential to live far beyond our lifetimes and have greater influence.

Phytochemical Exposure Prevents Cancer in Mice
Williams’s experiments have shown that the offspring of mice who ingest a phytochemical derived from cruciferous vegetables like broccoli, cabbage, and brussels sprouts during pregnancy were much less likely to get cancer, even when exposed to a known carcinogen. The same is true of the offspring of mice who were given green tea during pregnancy. After they were weaned, the offspring in William’s experiments never encountered these protective chemicals again, yet their exposure during pre...Even when exposed to known carcinogens.

Our Sinuses are Upside Down
Another consequence of our own shift from quadruped to biped concerns the sinuses, which give such grief to many of us (including me at the moment of writing) because their drainage hole is in the very last place a sensible designer would have chosen. Williams quotes an Australian colleague, Professor Derek Denton:* 'The big maxillary sinuses or cavities are behind the cheeks on either side of the face. They have their drainage hole in their top, which is not much of an idea in terms of using...Like back pains, its a product of our former quadrupedal nature.
