The answer is the placement of the eyes.
Explanation:
Developing depth perception through evolution for reasons such as hunting and movement was crucial in the survival of the species and it was made possible by the change in the location of the eyes to the front of the head. Because of the location of the human eyes and the distance of approximately 6 centimeters between them, they perceive slightly different images of the world and this also helps with the depth perception.
