Not sure about this with incarnation but I have one thought though..
1. Animals have "borned from start" behaviours that they havenīt learned yet, but develpe with out them knowing it.. Genes some say..
2. Because our suroundings change all the time. And no one trust in themslef enough. How many time have you caught yourself wondering if you turned the coffe machine off or not?
3.We havenīt got along becasue we have been to busy killing each other, making new properties, slaving others to our faith, building an egoistic future we think will be safe, we have never leraned it becasue to many donīt care about it...
How well I have answered your questions or not.. Er well.. Hmm, lets just say I have put in some jokes ther too! So donīt take all to serious OK!
