The Problems of Natural Selection

Natural selection has yet to equip little brown bats with a natural immunity to the white nose fungus, just as humans have yet to evolve an instinct to slow reproduction for the sake of our planet. Ultimately, our ape like instinct (must read: The Naked Ape, Desmond Morris) to pass on our genetic material prevails over our knowledge of the necessity of our limited resources. This weekend, I began thinking about the rate humans are reproducing, with little regard as to how their personal contribution (ie a child) will benefit society and our universe and whether their own resources are sufficient to care for said child. Is it a lot to ask that people don't reproduce until they are sure they can secure enough resources to provide for a child? I don't believe so. Modern society has provided a multitude of methods for living a relatively normal life and ensuring that eating, breathing, children aren't present before the intended time. I think a much harder task is creating a  little person that can help to benefit the earth and society as an adult. Unfortunately, because we are not hard wired to preserve our planet, we must actively work to keep this earth a good place, and the reality of creating such a being is difficult. For natural selection to occur and evolution to take place, genetic material must be passed to the next generation. It seems unreasonable that evolution could favor slower reproduction, but of course this has happened many times over the course of evolutionary time. Humans and bats reproduce relatively slowly compared with our mammalian relatives, and this trait must have arisen due to the better chance of survival and passing on genetic material when low numbers of offspring with long life spans are produced. Of course, we, like the bats are constantly being selected upon and evolving, and may eventually reach a resource bottleneck that limits our growth as a species. Heavy considerations...I may have to lay off the Morris.

  1. This is an interesting lesson in parenting for all of us. But this asks people to act on an individual level -- which in today's society, rarely breeds success. So what does this concept look like in legislation? When sanctioned by the law and government? One example would be China's "One Child - One Family" policy, enacted in part to reduce the country's ecological footprint. While controversial, drastic, and a harsh in its enforcement, after reading this article it makes me wonder if they aren't so crazy after all?
