why didn’t so-called psychic powers evolve?
certainly we know all sorts of remote sensory perceptions are possible in nature: eyesight (photonic detection), hearing (sound pressure wave detection) and even magnetic sense (electromagnetic field detection). moreover, human civilizations have invented technological sensors: cellular transceivers, radio transceivers, television transceivers. at least some of these theoretically align with the concepts of telepathy.
my hypothesis is that evolution did not find a way to select for these abilities. why not?
evolution did not select for psychic abilities because they conferred no advantages. in other words, they did not improve the survivability of any species.
telepathy seems like the simplest ability to ponder since we have all sorts of technological analogs for it.
at first glance, it would seem that a non-neuro, bio-chem-mechanical species could derive no advantage from it. what would telepathy do for non-intelligent species? without a brain, without thoughts, without higher cognitive functions, a radio signal could be used as a sign to predators that means, “come eat me”, but not much else.
an intelligent species, one with more advanced cognitive functions, might make use of telepathy. however, we have seen over the last hundred years that the amount of bandwidth transmissible over radio is extremely limited. even an intelligent species might not gain advantage with so little information. also, how does the species code for “my information” vs “your information”?
a highly intelligent species — sentient for now — might be able to take advantage of telepathy due its ability to transceive a sufficient amount of information that is coded to reveal “mine” vs “yours.” however, has there ever been a sentient species prior to or parallel with the hominids? also, from a psycho-social perspective, could a sentient species handle the effects of all that information? it seems that humans can barely handle their own thoughts, much less the thoughts of others. the psychological concept theory-of-mind barely registers for many humans of average intelligence. even in the best and the brightest, only one mind-theory at a time is possible, after which group theory (sociology) seems to replace that one focus. it seems likely that not even a sentient species could handle the information and processing requirements for telepathy to evolve.
an alternate hypothesis could be that evolution indeed selected for these traits by allowing the survival of the human species. furthermore, the human species is in the process of extending its own sentience into hyper-sentience via technological advances rather than bio-chemical ones. however, to simplify and focus, the only hypothesis i will explore here is the former.
