Anyway, I find the central theme of these works, i.e. aliens are responsible for the evolution of homo sapiens rather disappointing. In fact, this could be considered to a form of Intelligent Design!
Purely by chance, I read another book lately that supports Intelligent Design, albeit of a quite different kind, Black Order, 2005, by James Rollins. Dave blogged about this in May. This is a rollicking thriller set primarily in Europe with Nazis, spy-types, and bizarre science experiments. It really reminded me of Dan Brown's stuff--but better. Anyway, the main idea here is "quantum evolution": human minds via quantum mechanics actually cause the beneficial mutations that lead to evolution! I had never heard of this idea, but it is also clearly a type of Intelligent Design.
Who knew there were so many Intelligent Design versions out there!
Do you know of any others? (Besides the obvious!)
