1)	Three survival strategies are hunting, gathering, and scavenging. They were used to acquire food.
2)	We interpret behaviors from fossil evidence such as the kind of animals they hunted and the food they ate, the animals they fought to get the food and how they got the food and where they stored the food, such as a cave. We are not always accurate. For example, Raymond Dark found fossils in caves of all kinds of animals. He interpreted that our ancestors were murderous and hunted all animals, including their own kind, from all the fossils and weapons that he found. He also thought that they were killer apes. But, he was later proved wrong when someone discovered that other animals may have been scavenging bones and collecting it to one site. 
3)	The hominids did not cause the bones to accumulate but the porcupine and the leopard are two possibilities. 
4)	Early hominids did not us bones for weapons but were used for finding food. Evidence that we have is the antelope horns with microscopic wear, meaning that they were used for digging. 
5)	One scientist believes that the beginning of human technology is the stone tools found in the Rift Valley. They were made a few million years ago by removing a few flakes from a piece of rock. It was a useful cutting tool. 
6)	It is unlikely that early hominids were hunters because it was a tiny at ninety pounds armed with stone tools. If they had base camps like modern hunters, they would easily be prey. They scavenged carcasses and bones and placed them in one place for processing. 
7)	It is unlikely that early hominids lived near water because of the danger of predators, such as lions. They would not survive long.
8)	Three advantages of scavenging is that the hominids didn’t have to hunt down the animal, hominids could’ve eaten the bone marrow of large kills, and hominids could also pick nuts and fruits from the trees instead.
