Answer: Thermoregulation and to ensure an increased Demand for energy in the form of ATP through cellular respiration.
Explanation: Thermoregulation is a processes through which the body of wen blooded animals such as Human trys to maintain a constant internal environment,the sweating and other body cooling mechanisms take place in order to ensure that excess heat is dissipated to the environment and allow for fresh air in the form of Oxygen to penetrate the body through cellular respiration.
Due to the stress involved in vigorous exercise, the body spends more of it's energy, and the need for more energy in the form of ATP will be needed to sustain the vigorous exercise by replacement of the energy lost.
The answer is - apes.
According to the evolutionary theory the hominids originate from the apes. The first transitional species appeared in the Eastern African plateaus that created the needed evolutionary pressure for certain species to start using their legs more and to become bipedal, and also to develop their mobility of their thumb that had a new role in the newly created environment. The transitional species (from what is known so far) is the Australopithecus, which later on gave rise to all other hominid species like Homo habilis, Homo erectus, and at the end Homo sapiens...
