Why did our ancestors honing canine disappear?

Why did our ancestors’ honing canine disappear? They developed the ability to make and use tools for processing food. Explanation: Evidence for very early tool use coincides with the gradual loss of the honing canine. Tools would have made it much easier to process tough leaves and hard nuts.

What are the disadvantages of bipedalism?

Despite these advantages, bipedalism also has considerable disadvantages. The first is that it makes climbing considerably more difficult. Without the ability to grasp with the feet, hominids are less secure in an arboreal setting.
