The results of three preliminary pilot projects were published in October 2010—one of which uncovered a result that points to a youthful age for the human race.
In this pilot project, researchers examined in great detail the DNA base sequences from two families, including the mother, father, and child of each. A summary of the results appeared in Science, which stated that based on the data, “offspring inherit about 60 mutations that arose in their parents.”1
In large measure, the research for the “1000 Genomes Project” is aimed at pinpointing exactly which mutations cause which diseases. Knowing the number of new mutations that arise with each generation can assist with tracking the new diseases that they may cause.
The measurement of close to 60 new mutations occurring within the reproductive cells of each generation is less than a prior estimate of 100.2 This figure can help answer key questions. For example, does this number of mutations provide enough “fuel” for change to have innovated modern humanity from primate ancestors? Also, can the potentially harmful effects of this rate of mutation accumulation be somehow reversed before too many incorrect DNA bases compromise humanity’s survival?
Currently, the most accurate way to answer these questions is to use the freely downloadable population genetics modeling program called Mendel’s Accountant.3 Developed by a team of scientists, including Cornell University plant geneticist John Sanford, the program calculates the cumulative effects on the fitness (average survivability) of individuals that inherit mutations— some beneficial, some harmful, but mostly neutral—over multiple generations.
