Answer:
1. This individual likely used his teeth to compensate for a missing arm and hand.
2. Others must have cared for this individual in order for him to survive.
Step-by-step explanation:
The Neanderthal Shanidar 1 has serious physical problems that make it difficult for you to get on with your life. Her physical quality is so debilitating that it is likely that other individuals will take care of her so that he could survive. In addition, the presence of worn anterior teeth shows that the Shanidar 1 Neanderthal used the teeth severely, probably carrying objects. He had to use his teeth to make up for the lack of an arm and a hand.
