Understanding Snake Evolution and Locomotion

What evolutionary remnants do some modern snakes still possess?

• Wings

• Fully functional legs

• Vestigial limbs

• Fins

What is the primary method of locomotion used by snakes?

• Rolling

• Hopping

• Flying

• Undulating locomotion

Why might a legless body be advantageous for snakes?

• It makes them more colorful

• It prevents them from getting stuck in cluttered environments

• It helps them swim faster

• It allows them to fly

What evolutionary pressures led to snakes losing their legs?

• Need to fly

• Living in narrow environments

• Desire to swim

• Need to climb trees

What is a common trait among fossorial animals?

• Being legless or having reduced legs

• Having wings

• Having large ears

• Being brightly colored

Which of the following is true about skinks?

• They resemble snakes but are not snakes

• They can fly

• They have completely lost their legs

• They are a type of snake

What is the significance of the genus Bipes in the study of leg evolution?

• They have re-evolved their hind legs

• They have never lost their legs

• They can fly

• They have re-evolved their front legs

What is a potential reason for the re-evolution of legs in some reptiles?

• To improve swimming abilities

• To enhance climbing skills

• To increase speed on land

• To aid in digging

What is the main challenge in re-evolving legs for snakes?

• Complexity of developmental sequences

• Competition with other species

• Lack of genetic material

• Environmental constraints

What is the humorous analogy used to describe the evolutionary journey of snakes?

• Snakes and Ladders

• Ladders and Slides

• Snakes and Stairs

• Chutes and Ladders
