Maladaptive = reproductively unsuccessful
Please explain "devolution." Evolution is not a ladder; it's not a string of increasing complexity. Sometimes decreased complexity is adaptive and selected for. Evolution can both increase and decrease complexity
No. "Maladaptive" here is intended to mean any behavior likely to produce undesirable results. Humans don't need to make sense or produce good results. Therefore bad behavior and bad results are promoted resulting in devolution of the species. It should be remembered that
homo omnisciencis is distinct from all other life. In most meaningful ways humans are different because we have complex language and act on beliefs instead of logic.
All individuals are equally fit but a fit toad is completely different than a fit platypus so they are in no way interchangeable.
In humans being dumb can be the best bet and can result in the most offspring. Being unfit, disabled, and weak can be beneficial quite often. This is not true in the real world instead of the dream state in which humans live. Every year we make life simpler for the stupid and ignorant. I can't comprehend many of the symbols used as warnings, direction, and information and they no longer put words with them so my ability to read and understand English is a liability. The peter principle assures the ignorant and incompetent enjoy promotions so now days even once highly regarded institutions as the Army Corps of Engineers is almost wholly incompetent. As the government hands out money based on the number of babies one has as dependents it's hardly surprising every parent is not the ideal. It's been going downhill for 4000 years largely because things are forever being simplified until anyone can use it, understand it, or master it. Every year it's easier and easier to become a doctor. The memory, course work, and work load gets ever easier. Grades are handed out in colleges like candy so even dolts can pass if they can first get in. There's nothing new except the huge acceleration in the loss of standards. One doesn't even need to understand science any longer to get a grant, just agree with the dogma pushed by those who give grants. Now days we even roll over drunks to vote and many of those in prison who can't understand and follow the law can vote for our leaders.
Human behavior is maladaptive and superstitious. As the organs of society get simpler and the processes used to navigate our man made world get simpler the species is, no doubt, getting simpler as well. We have schools that don't teach and leaders who don't lead and voters that don't care.
But humans still control their environment so are in no danger at all of going hungry until reality catches up with us and we go extinct. Such is life in the big city. Everything is fine until it isn't any more. Then the feces is everywhere.
