The Wellcome Trust which funded a chunk of the research has acknowledged that individuals can be advantaged or disadvantaged because of their genetic makeup. They can, at least theoretically in the future, remix a human's level of optimism, her ability to dash 100 metres, the shape of her nose or even her capacity to imagine. Some children won't take after their mother or father but after an idea. What will be will be what we want. It all comes after all from the 38,000 to 115,000 controlling genes among the 3. 1 billion listed. Chapman, however, strikes a note of disagreement: "In theory, in the future, it might be possible to begin to change certain human characteristics over many generations by manipulation of certain genes. It's unlikely that any superpower would try to do this because of the complexities involved in altering bits of the genome and because it would be far easier to change people through manipulation of the environment rather than genes. For example, psychological or physical measures are much easier to put in place to influence the thinking of large numbers of people rather than attempting to change their genes through breeding."
