POPSEvo Psych "Like other critics, he has no doubt that evolution shaped the human brain. How could it be otherwise, when evolution has shaped every other human organ? But evo psych's claims that human behavior is constrained by mental modules that calcified in the Stone Age make sense "only if the environmental challenges remain static enough to sculpt an instinct over evolutionary time," Pigliucci points out. If the environment, including the social environment, is instead dynamic rather than static—which all evidence suggests—then the only kind of mind that makes humans evolutionarily fit is one that is flexible and responsive, able to figure out a way to make trade-offs, survive, thrive and reproduce in whatever social and physical environment it finds itself in"

POPSFixing My Gaze
"It is hard to imagine the dramatic nature of the sudden epiphany that stereoblind people have if they gain stereopsis, as when Barry saw the steering wheel floating before her. Stereoblind people perceive the world in two dimensions, as a flat display; they judge distance and depth by such cues as size, shading, and the partial obscuring of one object by another. They have to develop these techniques in childhood because they suppress the information coming from one of their eyes, since the data from both eyes fail to match. Nothing in the experience of the stereoblind can prepare them for what stereoscopic vision is like. If they get it, the experience can be overwhelming; it can even cause vertigo, as happened to Barry, and sensations of travel-sickness." "It is a pleasant and optimistic thought indeed, that at any point in life we might, if determined enough, be able to fix things, improve, mend, and grow in positive ways: even to see more clearly, and not just with our eyes."
