Evolutionary psychologists seek to understand how natural selection has shaped our traits and behavior tendencies. The principle of natural selection states that variations increasing the odds of reproducing and surviving are most likely to be passed on to future generations. Some variations arise from mutations (random errors in gene replication), others from new gene combinations at conception. Charles Darwin, whose theory of evolution has for a long time been an organizing principle in biology, anticipated the contemporary application of evolutionary principles in psychology.

Gravity causes the raindrop to accelerate to the ground at a rate of 10m/s². However, air friction acts against this gravitational acceleration by reducing the rate of acceleration of the raindrops. The higher the friction surface of the raindrops the lower the terminal velocity.
