The Bible places the Genesis 10 Babel dispersion about 100 years after the Flood (around 2,250 BC or around 3,200 BC based on the Masoretic or Septuagint texts, respectively). This coincides with recent human genome research that found evidence for massive genetic diversification about that same time. One of the research papers stated, “The maximum likelihood time for accelerated growth was 5,115 years ago.”[i] This places the beginning of the period of genetic diversification of humans close to the Genesis Flood and subsequent dispersion at the Tower of Babel, a point in time that the earth began to be repopulated through Noah’s descendants.
