Why Scurvy Shouldn't Exist

The video discusses scurvy, a disease caused by vitamin C deficiency, highlighting its symptoms and treatment. It explains the role of vitamin C in collagen synthesis and how most animals can produce it naturally, unlike humans. The loss of this ability in primates is attributed to a genetic mutation affecting the gulo enzyme. Despite this, early primates thrived due to vitamin C-rich diets. The video explores hypotheses on why the gulo gene was not eliminated, suggesting a lack of selective pressure due to dietary habits.

How does the lack of vitamin C lead to serious health issues?

What are pseudogenes and how do they relate to the gulo gene?
