Solution

Primatologists believe that chimpanzee cultures develop through a process of social learning. This means that younger chimpanzees learn behaviors, skills, and knowledge by observing and imitating older, more experienced members of their group. This is similar to how human cultures develop.

Cultural transmission in chimpanzees occurs in several ways:

  1. Vertical Transmission: This is when behaviors and knowledge are passed down from parent to offspring. For example, a mother chimpanzee might teach her young how to use tools to extract termites from a mound.

  2. Horizontal Transmission: This is when behaviors and knowledge are shared among peers. For example, young chimpanzees might learn a new grooming technique by watching and imitating their playmates.

  3. Oblique Transmission: This is when behaviors and knowledge are passed from one generation to a non-descendant generation. For example, a young chimpanzee might learn a new foraging technique from an older, unrelated member of the group.

These methods of cultural transmission allow chimpanzees to develop complex behaviors that are specific to their group, creating a unique culture.

The main, or central, idea of the passage is Chimpanzees and humans have surprisingly similar DNA. How does the detail in bold develop the main idea?Humans and chimpanzees descended from a common ancestor, a gorilla-like creature that lived millions of years ago. Even in light of this fact, it is astonishing to learn just how similar humans and chimpanzees are when it comes to their genes. In fact, the two species' DNA differs by only 1.2 percent. A laboratory comparison of chimp and human chromosomes—strands of DNA each containing approximately 1,100 genes—reveals a strikingly similar pattern. Perhaps surprisingly, chimpanzees are genetically closer to humans than to gorillas. Admittedly, the apparently small 1.2 percent variation between chimps and humans still corresponds to forty million differences in DNA base pairs. Still, the tremendous genetic similarity indicates that the chimpanzee (along with the bonobo, another ape) is our closest living relative.It suggests the initial reason why scientists pursued research on DNA similarity.It offers an alternative interpretation of DNA research.It specifies the extent of the genetic similarity.Submit
