Think about what you have read. If flies, spiders, beetles, and geckos all have hundreds of thousands of hairs on their feet, why did Gorb choose beetles?
A
Flies, spiders, and geckos are difficult for scientists to manage in a lab.
B
The hairs on the feet of flies, spiders, and geckos prevent them from climbing.
C
Beetles are easier to find than flies or spiders, and geckos are too small.
D
Flat tips on the hairs of beetles’ feet give them better sticking power.

The correct answer is D: Flat tips on the hairs of beetles’ feet give them better sticking power.
Explanation: Gorb likely chose beetles because their specific foot structure, particularly the flat tips of their hairs, enhances their ability to stick to surfaces. This unique adaptation provides them with better grip compared to other species such as flies, spiders, or geckos, making beetles an interesting subject for study in terms of adhesion and locomotion.
