Who cares what beast of burden Abram used when he traveled? I don't. I also don't know that camels are mentioned by name in the passage cited. There is an awful lot of useful information left out of the OP's story that would be useful in assessing the usability or credibility of the "study".
Problem with so much of this, as has already been pointed out, is that too many scientists (and not just in those seeking to prove higher criticism) start out with a conclusion in mind & construct "experiments" or "studies" to prove their position.
Again I ask, "Who ever claimed Moses was there when Abram was called?"
