In his landmark book Darwin's Black Box, biochemist Michael Behe wrote that "to appreciate complexity, you have to experience it." On today's ID The Future out of the vault, we conclude a three-part series with Dr. Jonathan McLatchie that dives into the complexity and design of sexual reproduction. In Part 3, Dr. McLatchie explains the design features of erectile function, the ejaculatory reflex, sperm chemotaxis, and the female egg cell. McLatchie reminds listeners how all separate parts work together as an irreducibly complex whole system. Be sure to catch Parts 1 and 2 of this informative series!
