Then and Now
Community life and chipped silicon: For over a million years we evolved biologically into circumstances resembling the images on the left. The bizarre variants on the right evolved culturally, much too fast for our biology to have kept up. It is a credit to the flexibility of our ancestral design that many of us manage to bend into the strange new molds. It is no surprise if we find the stretch uncomfortable, or that some of us never manage it at all.
