I love it when scientists argue. It generally means that there isn't really enough evidence to provide an answer, so the grant money is still up for grabs. The guessing will continue until a plurality of the community has written a papers supporting one position and have their professional reputations pegged to it. Then that position will become the accepted truth, and all further research to the contrary will be crushed with belittlement.
"Then that position will become the accepted truth, and all further research to the contrary will be crushed with belittlement."
Good summary.
