To the bewilderment of many researchers, the Paleo-Eskimos discarded the technologically advanced bows and arrows they brought from Asia, preferring instead to hunt with larger and heavier lances that required closer contact with dangerous game.

I don’t suppose it occurred to the researchers that
maybe advanced bows didn’t work too well in that
cold/wet climate?

[Theoria]

I read somewhere in my youth that if you wanted to fight a band of Indians. Ya did it in the rain. Water damages sinew and if any of the products were using such material, ie bowstring, it would hamper such weapons.

I'm sure a cold wet climate would hurt such items. And the advancement of teamwork and other ingenuity would result in different forms of hunting.
