Evolution of Eyelids and Mud Skippers

What was Charles Darwin's contribution to the study of vertebrate eyes?

• He discovered the first vertebrate eye fossil.

• He wrote about the evolution of modern vertebrate eyes.

• He invented a new type of camera lens.

• He was the first to study goldfish vision.

Why don't goldfish have eyelids?

• Their eyes are always wet and don't dry out.

• They live in the dark and don't need them.

• They evolved from birds.

• They have a special membrane instead.

What is the significance of gobies in studying the evolution of eyelids?

• They are the only fish with true eyelids.

• They are the largest group of fish.

• They provide insight into the transition from water to land.

• They have the most complex eyes among fish.

How do mud skippers manage to stay out of water for extended periods?

• They have a special breathing apparatus.

• They absorb oxygen through their skin and gulp air.

• They don't need oxygen.

• They have developed lungs.

What unique feature do mud skippers have for eye protection?

• They have a protective eye membrane.

• They use their fins to cover their eyes.

• They have true eyelids.

• They retract their eyes into their skull.

How do mud skippers' Proto eyelids function?

• They are a new muscle developed for blinking.

• They are a type of lens that protects the eye.

• They blink like human eyelids.

• They are folds of skin that cover the eye when retracted.

What does the study of mud skippers suggest about ancient vertebrates?

• They had a different type of eye structure.

• They had fully developed eyelids.

• They might have used a similar eye protection method.

• They did not have any eye protection.

What is the main focus of the research paper mentioned in the video?

• The habitat preferences of gobies.

• The development of new eye muscles in mud skippers.

• The origin of blinking in mud skippers and tetrapods.

• The diet of mud skippers.

What additional resources are mentioned at the end of the video?

• A podcast series.

• A comic and a research paper.

• A documentary on mud skippers.

• A book on vertebrate evolution.

What is the purpose of the comic mentioned in the video?

• To provide a humorous take on the research.

• To illustrate the anatomy of mud skippers.

• To explain the diet of gobies.

• To show the habitat of ancient vertebrates.
