What if the strange sightings of Bigfoot were a result of this creature crossing the ice bridge to North America, with its descendants evolving into a separate species?

如果大脚怪的奇怪特征是由于它穿过冰桥来到北美，其后代进化成一个独立的物种而造成的呢？

A dozen times, Perrault, nosing the way broke through the ice bridges, being saved by the long pole he carried, which he so held that it fell each time across the hole made by his body.

在前面探路的佩罗十几次踏破冰桥, 多亏他带在身边的一根长杆, 才把性命保住, 因为每当他掉进自己踩出的冰窟窿, 那根杆子便横架在冰上。

When there used to be an ice bridge, certain populations would stay separate from each other, so they couldn't come in contact and give each other their bacteria, their viruses, et cetera.

当曾经有一座冰桥时，某些种群会彼此隔离开来，所以他们无法接触并互相传播细菌、病毒等。
