If i asked the question "why did humans form a hibernative monophasic sleep cycle? most people would say because at night we slept in caves and shelter to escape the dark and we evolved to sleep that way" even though that's not the case with out genes at all. People often attribute things that are entirely behavioral to evolutionary reasons and that's what i think the quotes trying to illustrate.
Baby's start out sleeping Polyphasically but soon adapt a natural night/day cycle due to the humans around them (mirror neurons, reinforcement, lighting). Now i dont know if this proposed experiment would-be very feasible or ethical but most people discount it because they "understand" evolution.
Discounting other theories unjustifiably, or overusing a particular theory past it's explanation is one sin. Not understanding a theory is another however. I think that many people who draw such false conclusions still base them on a pretty clear understanding of the core of evolutionary theory, i.e. mutation, gene exchange, selection, reproduction.
Here's the new quotes thread, for all those quotes you were going to post.
