What anatomical features makes it possible for Homo erectus to be a biped runner. Pick only one feature discussed in this week's material that allowed Homo erectus to be a biped runner. How is your chosen feature different from Australopithecus aferensis equivalent feature? Briefly explain the difference. Lastly, I would like you to briefly explain in your own words how endurance running would enhance the fitness of the Homo genus.

Explanation:

The early homo erectus had tendors, ligament and mass spring which enables them become adapted runner.

The mass spring is energetic contributing to high speed.

The mass spring is mechanism aids in the exchange of kinetic energy and potential energy in the presence of tendors and ligaments that stores up the energy this enables them to run.

Nocturnal ligament that is present in homo erectus the helps to keep the head in position is absent in Australopithecus. This ligament usually activated during running in erectus and makes running more convenient.

Endurance running helps the early homo's to survival as they often run to get preys and animals to feed on. Because they do not have all the tools needed to hunt, the need to move in close range to get the prey hunted.
