question 3 of 10
human beings as we know them have existed for about ______ years.

a. 65 million
b. 10,000
c. 200,000
d. 250 million

Explanation:

To determine the correct answer, we refer to anthropological and paleontological knowledge. Anatomically modern humans (Homo sapiens) have existed for approximately 200,000 years. Option A (65 million years) is related to the time since the extinction of dinosaurs, B (10,000 years) is too short (related to recent human history like the Neolithic), and D (250 million years) is far too long (before mammals were dominant).

Answer:

C. 200,000
