Cultural differences: You look at people living in deserts and historically they are likely to come up with monotheistic religions. Look at people in rainforest and they come up with polytheistic religions. Look at people in east Asia, that live in flat plain areas and they grow rice, which requires collectivist farming and you get a very collectivist mindset about cooperation. Get people in the hill countries there and they grow wheat which is done in individual families and you get the same individualistic mindset of people living in Manhattan. All of it ecologically shaped. Then if you go even further back because if you are talking about genes anywhere along the way, you are talking about the evolution of genes and what you wind up seeing is evolution has sculpted different primate species into having different characteristic levels of aggression, some primate species have virtually none and then some have immensely high levels and there’s all sorts of biological traits that go along with the two extremes and then there is us and we are somewhere in the middle of the two extremes. If you want understand why this behavior occurred you have to take into account everything that happened 1 second ago to a million years ago. Well what do you conclude from that? Obviously it is quite a complex situation but we have to be real careful about associating why and what’s causing these things. Especially if we are going to harshly judge someone based on limited information. Cause we have a dark history of genocide based on lose accusations formed by the opinions of people who think they know what they are talking about. Every single biological fact presented is subject to change over time. Ecosystems change, thousands of years ago the Sahara was a lush grass land filled with hippos and giraffes. Cultures change, in the seventeenth century the scariest people in Europe were the Swedes who spent that whole century rampaging all over Europe and the swedes have not had a war in 203 years, they changed… and most of all, brains change, circuits form, neurons weaken, patterns grow, parts of brains expand and as a result people change and they can change extraordinarily.
