Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.

The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.
In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.
The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.
