Answer :
Final answer:
The killer ape hypothesis suggests that human aggressive behavior evolved from naturally aggressive ancestral primates. This idea is one among several considered by biological anthropologists when studying the evolution of human intelligence, technology, and culture.
Explanation:
The killer ape 1) hypothesis is the idea that humans evolved aggressive behavior from killer apes. This hypothesis suggests that ancestral primates were naturally predisposed to aggression and that this trait was a significant factor in the evolution of human behavior. The hypothesis proposes that the ancestors of hominins had a propensity for violence, which was utilized for survival and dominance.
The hypothesis aligns with observations that large-scale and deliberate killing is a uniquely human characteristic, although aggressive behavior can be seen among other primates, such as chimpanzees. Biological anthropologists consider multiple hypotheses when studying human evolution, including the killer ape hypothesis, to gain insight into the origins of human intelligence, technology, and culture. While humans share many biological traits with other primates, our complex behaviors, such as tool-making and warfare, distinguish our evolutionary path.
