Are a Pokemon's evolutionary moves pre determined?

It makes a difference in CP for catching sometimes (ie. they encounter the same Pokemon at different levels), but the IVs, moveset, weight, and height of the encountered Pokemon are the same. Like if the lower level Pokemon with the lower CP was powered up to the the same level as the other one, they would be exactly the same. My brother and I catch the same Pokemon all the time. When they get evolved though, that's just a roll of the dice for movesets. It's random for what is available currently.
