How did Ross prove mosquitoes spread malaria?
The proof lay in the patient tracing of the parasite's life cycle. I engaged in rigorous observation, first in birds and then in humans. My experiments involved exposing mosquitoes to infected individuals, then dissecting the insects at various stages to observe the parasite's development within their bodies. Subsequently, I controlled mosquito populations and observed the impact on malaria incidence. The crucial step was the identification of the parasite in the mosquito's salivary glands, the very route of inoculation. It was a methodical, almost detective-like pursuit of causal chains, where each piece of evidence confirmed the next.
