> A group of monkeys being raised in an indoor arboretum had some injuries, and the scientists installed much more stout sticks and secured the vegetation. No more injuries due to broken branches, but when the monkeys were introduced to the wild, instead of swinging & leaping through the leafy canopies like their wild brothers, they cowered at the trunks. They'd completely failed to learn while young the skills required, and so the release failed for that generation. Do you have a link about this one? Sounds interesting.
