I believe this is the same Glenn Morton as Morton's demon.
His conclusion:
So, I would say, that there very well may be linguistic evidence of a common root for these words throughout the world's language. This is consistent with the Biblical assertion that humanity once spoke a common language. That being said, the thing wrong with young-earth views of this is that they place Babel far too late in history.
I wonder if the Exodus story is really the story of the emergence of the human race from Africa. Think about it.
Our ancestors left Africa during an ice age. The sea level, including the Red Sea, was much lower. Maybe it could be waded across, or you could go from sandbar to sandbar across.
Now the ancestors of everyone except the Semites moved away, but they stayed put, on both sides of the Red Sea. When the ice age ended, they were still telling the story of crossing it, but now it was impossible.
So they, ahem, modified, the story by throwing in Pharoah, and the plagues, and the miraculous parting, etc.
