  1. 80 grams is 2.8 ounces, not 3 pounds. Below 0.2 pounds. Still quite a bit of mushroom but not insane. Talking of melanin as being a left over from a time when there was more radiation seems weird to me. It protects us from UV radiation in our skin too!
  2. Tarwin Stroh-Spijer: "Talking of melanin as being a left over from a time when there was more radiation seems weird to me. It protects us from UV radiation in our skin too!" — Precisely, UV radiation reaching the Earth surface used to be much stronger when the O2 concentration in the atmosphere was lower and the ozone layer, thinner or non-existant.
  3. Is there any accounts of people with lower amounts of melanin in their skin being more susceptible to radiation than someone with darker skin?
