Question

multiple choice question
which type of human hair is thought to be mostly vestigial (an evolutionary remnant with little to no modern importance)?

• beard and pubic hair
• eyebrows and eyelashes
• scalp hair
• hair on trunk and limbs

Explanation:

Beard and pubic hair play roles in signaling maturity; eyebrows/eyelashes protect the eyes; scalp hair insulates the head. Hair on the trunk and limbs has no significant modern functional purpose, making it the vestigial trait.

Answer:

hair on trunk and limbs
