Scientists finally have finished mapping the entire human genome, nearly 20 years after most of the map was complete. In new research this week, a team reports they achieved a gapless genome sequence that accounts for 8% of genetic information not previously known. This research completes the work that was released in 2003 by the Human Genome Project. That work included a nearly complete rendering of the human genome, except for the heterochromatin regions. According to Evan Eichler, an author of the study, what we learn from this data could very well revolutionize our current thinking about the inherent genetic variations in our genes, how they have affected our evolutionary journey and how health problems can arise from mutations.
