Question

According to one study , people living near the equator often have tall and slender bodies . How could a tall and slender body be a useful adaption for a person living near the equator

Answer 1

Body shapes and sizes are key factors that can determine how heat is lost or gained by the environment. People around the equator tend to be taller and slender with long limbs. This is important because it increases their surface area to volume ratio. What this means is that most of their body parts will be in contact with the environment hence making it easy fro their bodies to lose heat to the environment.
