>>> 1. Biology has never selected genes to maximize longevity, only to maximize healthy breeding. There are very likely tons of genes that make sense as a growing child but are harmful at a later age, e.g. a post menopause/vasectomy adult does not need the genes to create gametes but those same genes may be causing cancerous issues for some. This is being debated, in the sense that there is a relationship between longevity and breeding. How ? For a human to be able to have kids every 2-3 years - instead of 6-7 in apes - older individuals have to be healthy enough to bring a calorie surplus to the mothers.
