They've oftened mentioned "Earth Skills", which leads me to guess there was some class they were taught to keep the knowledge alive until the time came they could return to earth. I get the impression they all were taught this, but of course, some people are just better at some things than others. For example: Finn may be considered the best tracker, but it's possible they all were taught that, but they just didn't do as well with it as he did.

Seriously, it wouldn't make sense for just one person to be taught each thing. What happens if that person dies? In fact, Finn did die at the end of the episode that ran the night before last. It would be very poor planning for them not to make sure more than one person has a given skill. Having 97 years to work on this, I'd lke to think someone on board the Ark had considered this as well.
