That is not true. One of the many factors that make human tribes competitive is grandparents. Grandparents can help in many ways especially with child rearing and retain knowledge not available to younger people. Having more healthier and longer lived grandparents enhances the relative fitness of those of breeding age. There is a similar effect with homosexuals tending to contribute to tribal fitness thus enhancing reproductive fitness of the tribe.
- 1shooner 4y agoAre there any data to support this?
- smt88 4y agoNot yet. My ex is a geneticist who studies the evolutionary basis of aging and this is one of the hypotheses for human longevity being what it is, but there isn't hard proof so far.
- 1shooner 4y ago>studies the evolutionary basis of aging This sounds like it would be fascinating in general.
- oicu812 4y ago>> similar effect with homosexuals tending to contribute to tribal fitness thus enhancing reproductive fitness of the tribe. If they want to reproduce, don't they have to search outside their tribe for a sperm/egg donor and possibly surrogate? So at least 50% or more of their reproductive health comes from outside the tribe?
- m0llusk 4y agoI'm talking about behaviors and you are talking about desires. These are very different contexts. Attempts to characterize behavior show homosexuals more commonly staying with parents and supporting relatives. The usual explanation for this is that they are not interested or able to compete in the usual mating and paring rituals. It isn't that they want to reproduce so much as they want to contribute to the tribe and in doing so result in the reproductive capacity of the entire tribe being increased.
