Prompted by listener emails, we discuss the topic of evolution and our thinking on it, and how our thinking on it has evolved over the years. This leads to some reading from the excellent website of Dr. Eugene McCarthy and his theory of hybridization and stabilization as a better version of the evolutionary theory. This is a topic with a lot of details, many of which we don't fully understand. We intend to work on it some more and perhaps dive deeper in the next episode.
