Area of Science:

  • Evolutionary biology
  • Human physiology
  • Medical history

Background:

  • Charles Darwin experienced a debilitating 40-year illness with diverse symptoms.
  • Previous diagnoses for Darwin's condition, including poisoning and psychosomatic disorders, lacked conclusive evidence.

Discussion:

  • This study proposes systemic lactose intolerance as the cause of Darwin's chronic ailments.
  • The timing of symptoms aligns with lactose digestion in the large intestine.
  • Darwin's family history suggests a genetic predisposition to hypolactasia.

Key Insights:

  • Darwin's symptoms, including vomiting and gut pain, precisely match systemic lactose intolerance.
  • A genetic component is indicated by his family's medical history.
  • Recovery occurred coincidentally upon reducing dairy intake.

Outlook:

  • Revisiting Darwin's illness through the lens of lactose intolerance offers new perspectives.
  • This case underscores the evolutionary significance of lactose in mammals and humans.
