So I rest my case. I don’t think you can have a disagreement among scientists unless they actually believe something contrary to one another. The fact that there was research, teams, reports, commentaries would imply, I think, that this was a hypothesis that was under serious consideration, and disagreement. Anyone can find this information if they are willing to look. Information for links has been given, and articles and magazines named. Just based on this alone, how could someone claim that it is “absurd” that any scientist ever believed whales and hippos are on the same evolutionary branch?
