Question

What are the defining traits of anthropoids?

a. diurnal, poor vision
b. diurnal, have color vision
c. diurnal, black and white vision
d. nocturnal, color vision
e. nocturnal, poor night vision

Answer 1

Anthropoids are mostly diurnal with color vision, large brains, and reduced reliance on smell, making option b (diurnal, have color vision) the correct answer.

Step-by-step explanation:

The defining traits of anthropoids, such as monkeys, apes, and humans, include being primarily diurnal (awake during the day and asleep at night), having color vision, and a reduced reliance on the sense of smell. This contrasts with prosimians, which often are nocturnal and have a greater reliance on smell. Anthropoids typically have traits that include depth perception, binocular vision (seeing one image with both eyes), and relatively large brain sizes, which also indicates an enhanced capacity for processing visual information, including color.

Therefore, the correct answer to the question is: b. diurnal, have color vision.
