Humans are only walking digestive tracts. From an evolutionary perspective, all other organs originated from a primitive gut and have only one purpose: to serve it.
(credits to /u/susieq0044@sh.itjust.works who phrased it so well in this post, even though i had the thought already years ago)
i mean… not really. if you can accept that humans are animals and animals, having evolved from a common ancestor, all share a common “x is just a walking y”, that would have to be gonads. consider as a counter example, bugs that metamorphose into an adult form completely lacking intestines and even mouths. yet they retain their reproductive organs and die once they use them to reproduce. humans are just walking gonads with a bunch of supporting hardware attached.
But aren’t the gonads also not real in this analogy, since gonads evolved (skipping some steps) from single celled asexual reproduction and horizontal gene transfer. So aren’t you technically just your DNA?
ok how about this: the brain serves the muscles to perform more targeted movements, which serve the gut to collect food, which serves the gonads.
The gut exists to supply nutrients to the gonads. The muscles to feed the gut and handle the gonads output. The nervous system to control it all. Consciousness of it all, in all it’s utterly pointless glory, purely because apparently there’s a dark sense of humour somehow buried in universal statistics.
