Evolution is garbage science and, as garbage science goes, a spectacularly dangerous and pernicious variety with two world wars and a couple of hundred million dead bodies lying around on account of it. The out of control arms races and isms which brought those wars and the massacres associated with communism and naziism about all began with the idea of a peson viewing his neighbor as a meat byproduct of random events rather than as a fellow child of God."Children of God" had been murdering each other for ages(remember the pope wars? To be accused of "popery" in England was a death sentence). Industrialization and the rationalization of human government were the cause of the suffering of the 20th century. One thing that people forget is that many of the totalitarian monsters of the 20th century(Mao, Stalin and Hitler) had huge beneficial effects on the standards of living of their respective societies. Life expectancy and standards of living in China(even counting the starvation in Mao's little "experiments") skyrocketed.
With the single exception of the 30-years war, European wars prior to 1900 were basically gang-fights between royal houses and in 1913, Europe had just gone for an entire century without a meaningful war. Conversely, to find anything comparable to the wars of the last century, you need to go straight back to Chengis Khan.
