Quotes
"History shows that representatives of consecutive evolutionary stages are rarely in mortal conflict. Multi-celled organisms didn't drive out single-celled ones, animals haven't exterminated all plants and automobiles neither killed nor eliminated all pedestrians. Indeed, representatives of consecutive evolutionary stages build symbiotic relationships in most areas of common interest and ignore each other elsewhere, while members of each group are mostly pressured by their own peers." - Alexander Chislenko
