Native Americans learned to stalk by studying predator-prey interactions. To survive, drab-colored animals such as deer, rabbit, and fox have evolved colour vision. Color perception isn’t necessary for survival because they can blend in with their surroundings as predators or prey. Their eyes’ rods now have the upper hand in detecting motion in their area of vision. Working with the wind and being camouflaged can help you blend in, but movement is the greatest offender when it comes to blending into the forest. Wild creatures may be alerted by sound, but it is human movement that leads them to vanish like smoke into the brush.
