Thanks for sharing this discrepancy!

Indeed, the "beaver as relevant tool as major driver" does actually not exist in schools in EU mainland; the chance is higher you hear about the porks brought by first European-immigrants that they used for food production because of their fast reproduction numbers.

(and porks are easy to deal with, they eat everything; Once I heard someone from crime enforcement saying: "the perfect murdery would be to feed the dead body to a herd of porks because they would even eat the teeth from the body")
