>improved memory is absolutely something evolution would select for in primates, especially humans.
What if it makes people more scared, because they can remember past experiences better. This could lead to less procreation and thus inverse selection pressure.
Only because a trait is superficially good it doesn't mean nature would select for it.
- Erlich_Bachman 8y agoWhy would a memory enhancing drug only increase rememberance of negative memories and not the positive and loving ones? Such people could become more active, motivated and procreating more because life seemed more motivating for them because they remembered all the good from the past also?
- buboard 8y agoit would increase both, but negative ones can have bad, debilitating consequences in life (cue PTSD, phobias)
- carlmr 8y agoThat's not the point, I was just giving an example. It could have millions of effects and whether evolutionary selection would favor these genes is not trivial.
