And in terms of evolution it makes sense. A lack of vitamin d early in life could effect reproductive success. Skin cancer in your fifties not so much. There just isn't selective pressure.
- refurb 4y agoAnother factor to layer on as well! As humans developed, evolution didn't have to create the optimal system, just a system that gets the organism to reproductive years. After that? Irrelevant. That could point to the challenge of fixing diseases of aging. A good analogy is programming - if the program you came up with uses 8 bit variables, and that limitation causes problems later, well, you're going to have to start from scratch to fix it.
