Understanding Tails and Human Evolution

What is one of the primary functions of tails in most mammals?

• To store fat

• To steer through the air

• To maintain balance

• To scare off predators

Why do humans not require tails for balance?

• Because we have a lighter head

• Because we walk upright and use gravity

• Because we have a longer spine

• Because we walk on all fours

What is the evolutionary advantage of walking on two legs?

• It allows for faster running speeds

• It conserves energy by using gravity

• It helps in climbing trees

• It improves balance on uneven surfaces

What is the human tailbone a remnant of?

• A vestigial limb

• A parasitic twin

• An ancient tail

• A spinal deformity

In rare cases, what are the tail-like structures in newborns often composed of?

• Bone and muscle

• Cartilage and skin

• Fat and tissue

• Nerve and blood vessels
