How can it be although I'm really very antisocial? Nevertheless, I hurt solitude in duration. How come? And why do I want to be loved by someone? Why can not it care, why can not me all care for me, and indifferent? Why do I even want a partner? Why do I have wanted?
Adopted this has genetic reasons, then the simple should be explained
You like solitude> fewer chances for reproduction
You like partners> More opportunities for reproduction
Now a few generations and there you have it, people do not like the loneliness in the majority
Because that is normal. We humans are not made but being alone - we need social contacts to survive.
