Question

What organism from the example are most closely related to humans? How do we know this?

What organism do they share a common ancestor with?

Answer 1

Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.

Step-by-step explanation:

Answer 2

The organism that is most closely related to humans is the chimpanzee. We know this through various forms of evidence, including genetic, anatomical, and behavioral similarities between humans and chimpanzees. For example, the DNA sequence of chimpanzees and humans is approximately 99% identical, and many anatomical features of chimpanzees are very similar to those of humans.

Humans and chimpanzees share a common ancestor that lived between 6 and 8 million years ago, which is thought to have given rise to both the human and chimpanzee lineages. This ancestor was likely a hominid species, similar to modern-day gorillas, chimpanzees, and bonobos, but not identical to any living species. Over time, the evolutionary paths of humans and chimpanzees diverged, leading to the distinct species we see today.
