The Strange Case of the Missing Sunscreen Gene

The video discusses how some organisms naturally produce their own sunscreen compounds, unlike mammals who lost this ability due to evolutionary changes. It explains the discovery of UV-protective compounds like mycosporine and gadgesol in various vertebrates, and how these genes were likely acquired through horizontal gene transfer from algae. The video also covers how mammals adapted to darkness, losing the need for such genes, and explores modern research into environmentally friendly sunscreen alternatives.

What is the significance of the genes for making gadgesol found in various vertebrates?

How did mammals lose the ability to produce their own sunscreen compared to other vertebrates?

Describe the process of horizontal gene transfer as it relates to the evolution of sunscreen production.

What adaptations have mammals developed to protect themselves from UV light in the absence of gadgesol?

What are the potential benefits of genetically engineering yeast to produce gadgesol?
