Earlier quoted context omitted.
For the case of suicide there is a potential mechanism in which there is a benefit for genes to pass. We can imagine a hardship scenario in which removal of oneself leaves more resources to the remainder of one’s group, which is likely to be their kin and have shared genes. In this case suicide would be adaptive for the genes to pass on. This is nor far fetched because we see other self sacrifice behavior (e.g. betwe…
People almost never commit suicide for "leaving more resources to the tribe". They do because they are complex persons living in a complex environment that is radically different from the savannahs for which our genes evolved. Likewise, your evolutionary arguments for motivation are equally useless. Evolution takes place on much larger timescales than the changes in our environment. 3000 years is almost nothing in te…
We are not talking about why people might be committing suicide now, we are talking about how the genetic disposition for suicadility might have passed along. To give context, 50% of the people will seriously have suicidal thoughts in their lifetime for about a week or two (so few actually do).
> Likewise, your evolutionary arguments for motivation are equally useless.
You misunderstand. We are not talking about an environment - gene mismatch, therefore the timescales are not relevant at all. I am positing a near impossibility of complete lack of intrinsic motivation to have passed genetically, regardless of timescale or even species.
