The style of writing in naturalism incorporates a scientific approach that emphasizes detachment and objectivity. This is illustrated in "The Human Drift," which includes scientific references:
We hypothesize that these early migrations took place, similar to how we understand that the initial bipedal creatures evolved from some relation of the quadrumana by transforming “two opposable thumbs into a pair of large toes.”
Another notable feature of naturalistic literature in "The Human Drift" is the portrayal of humans as essentially “beasts,” depicted as uncivilized and savage:
In the hazy ancient world, we observe of ghostly tribes, conquering, hunting for sustenance, forming primitive societies, collapsing, succumbing to the might of stronger enemies, and ultimately fading away.
Naturalist authors contended that human existence and experiences are influenced not solely by individual decisions but also by natural forces such as famine or floods:
Moreover, man has been afflicted by various other disasters beyond warfare. Floods and famines are significant contributors to population reduction—allowing for demographic shifts... The crop failure in Ireland in 1848 led to 1,000,000 fatalities.
Naturalism also relies on Darwinian concepts of “survival of the fittest.” This is supported by London’s statement:
When his evolution allowed, he crafted superior killing tools compared to the original fang and claw. His focus was on creating more effective murder implements.
