Question

Question Number 1:

Humans have a lot of homologous structures in common with other animals, and several of these structures are no longer in working order in human bodies. These nonfunctioning structures are called vestigial structures. They still show evidence of common ancestry, but they do not do the same things in humans as they do in other animals.

Listed below are mostly vestigial structures. Select the one that serves a purpose in humans.

A. ear muscles: ability to wiggle ears in humans versus rotating ears to hear predators in prey animals like deer and rabbits

B. tail: tail bone in humans versus long tails for balance and communication in other animals like lizards and wolves

C. hair raising: goosebumps in humans versus raising hackles to appear larger and aggressive in other animals like cats and monkeys
