Episode #157: Hybridization and Species

Continuing on from last week's discussion, we read and respond to emails about evolution and how people think about it in various ways, with analogies and references to consciousness and a possible spirit realm, or other more mechanistic ways of thinking about it. We talk to the Watcher about genetics and genetic expression in reproduction, and chromosome pairing.

Then we continue to dig through the information on MacroEvolution.net and the work of Dr. Eugene McCarthy, and his Stabilization Theory of evolution. We read about the "fuzzyness" of terms like "species", and how the entire process of the categorization of life is based in an idea of immutability of form, even though that concept has long since been discarded.
