Where is every one? Why haven't we been visited by alien races, made contact with aliens, or even discovered a hint of an alien race? Ever since Fermi asked this simple question, people have been coming up with answers as to why we don't see aliens. Some solutions are scary, but I think a potential answer could be found by looking at our own solar system.  ..read more

In researching astrobiology for my up coming book, I've started to view the evolution of life and civilizations in a paradigm shifting way that challenges the very basics of our understanding of evolution. Listen in as I explain why I think evolution is progressive.  ..read more

Why do we reproduce sexually, why do we look similar to our parents and siblings, but are different? In this episode, I take a close look at the origins of sexual reproduction, how meiosis generates genetic diversity, and Mendel's basic principles of inheritance.  One of the major themes in my classes is that biology is complicated, and that goes for genetics so I also discuss  extensions to Mendelian genetics. And lastly, I explain several common misconceptions about inheritance.  ..read more
