Paradigms Lost and Regained

I just finished Paradigms Regained by John L. Castro ( ISBN 0-316-64816-7).  A great science read for the Big Questions. His conclusions-

1) Life arose out of natural physical processes here on earth, probably via an RNA world.

2) Human behavior patterns are dictated primarily by genes.

3) Human language capacity stems from a unique, innate property of the brain.

4) Didital computers can ( in principle ) think.

5) We cannot communicate with extraterrestrial intelligent beings in our galaxy even if they exist.

6) There is an objective reality independent of an observer.
