Question

general nomenclature classifies humans by the name homo sapien. which two organisms are the closest in relationship to human beings? choose two (2).
pan troglodytes
homo neanderthalensis
gorilla gorilla
homo erectus

Explanation:

• Pan troglodytes (Chimpanzee): Chimpanzees share a high degree of genetic similarity with humans (about 98 - 99% of DNA is similar). They are part of the Hominidae family, which also includes humans.
• Homo neanderthalensis (Neanderthal): Neanderthals are an extinct species within the Homo genus. They interbred with Homo sapiens, and modern humans (outside of Africa) have some Neanderthal DNA (1 - 4% on average).
• Gorilla gorilla (Gorilla): While gorillas are great apes (like humans), they are in a different genus (Gorilla) than humans (Homo). Their genetic similarity is less than that of chimpanzees and Neanderthals.
• Homo erectus: Homo erectus is an extinct species of the Homo genus. However, it diverged from the Homo sapiens line earlier in evolutionary history compared to Neanderthals.

Answer:

Pan troglodytes, Homo neanderthalensis
