El ojo ¿diseño o evolución?

The video explores the complexity and evolution of the eye, starting with its intricate design that challenges evolutionary theory. It traces the eye's development from simple light-sensitive spots in single-celled organisms to complex structures in multicellular animals. The Cambrian explosion accelerated eye evolution, leading to advanced features like the camera obscura and photoreceptors. The video also discusses the formation of the cornea and crystalline lens, and how eyes evolved independently in different species through convergent evolution, highlighting structural differences between human and octopus eyes.

What did Charles Darwin say about the eye that reflects its complexity?

• It is a simple organ.

• It gives him chills.

• It is evidence of intelligent design.

• It is not useful for evolution.

What is the function of the ocular macula in single-celled organisms?

• To sense light and dark.

• To detect detailed images.

• To see in color.

• To focus on distant objects.

During the Cambrian explosion, what advantage did sunken eyespots provide?

• Enhanced image clarity.

• Protection from predators.

• Ability to detect colors.

• Improved light direction detection.

What evolutionary development allowed animals to see images?

• Emergence of the pupil.

• Creation of a camera obscura.

• Formation of the cornea.

• Development of photoreceptors.

How did molting contribute to eye evolution?

• By creating a flexible lens.

• By enhancing color vision.

• By developing the retina.

• By forming a protective cornea.

What is a key difference between human and octopus eyes?

• Octopus eyes have a blind spot.

• Human eyes have nerves behind the retina.

• Octopus eyes evolved from a different ancestor.

• Human eyes have nerves in front of the retina.

What common gene is involved in eye development across species?

• Photoreceptor gene.

• Retina gene.

• Ocular gene.

• Pax 6 gene.
