The two foot beavers probably ducked.

Normally, when you talk of "natural selection", and "survival of the fittest", you would think that the 6 foot beaver would push the little beavers out of the way, and only the bigger mammels would survive.

What actually happened, says that all the little mammels lived, all the little male animals got to mate with the female animals, and all the big mammels eventually died out, regardless of food source or living conditions - that is contrary to the obvious in who survives and who doesnt when brute force determines who takes over making the dam and who gets to mate with female beavers.
