AI Thread Summary
Optical illusions occur because the brain attempts to interpret images based on visual cues and context, leading to multiple valid interpretations. These illusions often present two distinct perspectives within the same image, such as the well-known example of the faces versus the vase. Many individuals may not recognize the alternative interpretation until it is pointed out, highlighting the brain's reliance on prior knowledge and assumptions when processing visual information.

Most people won't even notice the alternative interpretation until someone tells them it's there.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional.
