Declaration by Dr. David Fu-Chi Mark, a distinguished molecular biologist:
A human being at an embryonic age and that human being at an adult age are naturally the same. The biological differences are due only to the differences in maturity. Changes in methylation of cytosine demonstrate that the human being is fully programmed for human growth and development for his or her entire life at the one cell stage.
