debating whether to take charge of their own evolution. The average life span in the developed world will be 90, diseases will be diagnosed before symptoms appear, many humans will already be genetically modified and patients with heart diseases, cancer or dangerous infections will be treated with prescriptions tailored to their own genetic makeup, according to Francis Collins, one of the leaders of the project to sequence the entire human genome. By 2010, Collins told in a major international biotechnology forum in France this week, there could be predictive tests for at least 12 hereditary conditions, and scientists would understand the role that genes played in most common diseases.
