How the human code has been unraveled: Here's what experts suggest

Last week, humanity got to learn 8 per cent more about homo sapiens. Scientists completed sequencing the human genome, the goal of a project that began in October 1990.  (A genome is the complete set of genetic instructions encoded in an organism.
