How could upright walking have helped early hominins stay cool?

A) increased convective heat loss
B) cutaneous evaporative cooling
C) minimized skin exposure to the sun
D) b and c
E) a, b, and c

Convective Heat Loss

The loss of body heat to the surrounding environment due to the movement of air or water molecules across the skin or surface.

Cutaneous Evaporative Cooling

The process of heat loss through the evaporation of water from the surface of an organism's skin, aiding in thermoregulation.

Upright Walking

The ability to walk on two legs with the body held vertically, a key characteristic of humans and their ancestors.
