For Digimon World, you have 6 battle stats: HP, MP, Offense, Defense, Speed, Wisdom. You also have 3 shown gauges: Happiness, Discipline, Poop (if this one is completed, you will have Sukamon). You also have a hidden gauge called Care Mistakes CM (not feeding your Digimon if hungry, making your Digimon poop on the ground, making your Digimon tired, make him continue activities when he is sleepy). You also have the weight: some food will increase your weight (Meat), other will decrease it (Mushroom)
For the evolutions:
Baby 1 to Baby 2, 1 evolution only, so nothing matter.
Baby 2 to Child, they will compare 2 stats. Depending of which one is higher, you will have 1 of the 2 possibilities (if it's equal, I suppose it's random). If they sleep in Kunemon's Bed, each Baby 2 will evolve into Kunemon.
Then it becomes complex. For Child to Adult, you have 4 hidden conditions, 1 is the stat condition, you need to have this one. They corrected it in the other games, but in the original it was all or nothing. Let's say the stats condition was 1000HP/MP and 100Off/Def/Spe/Wis. If you had 9999 HP/MP, 999Off/Def/Spe but only 99 in Wis, you failed and your Digimon evolved into Numemon.
For the others 3 conditions, you need 2 of them. They can be: being above or below a certain number of CM, one gauge being at a certain percentage, having a certain weight, doing a certain number of fight, having your Digimon losing a fight etc. If you failed you will have a Numemon (which can be a good thing if you are far enough in the game, because, if you go to Toy Town, you can make it evolve into Monzaemon, so an easy Perfect). Another specific evolution is Nanimon. You need to scold him again and again.
For Adult to Perfect, it's the same, but, if you failed, your Digimon will die with an stats inheritance (1 to 10%). And as the city becomes bigger, gaining stats becomes easier.
