Richard Dawkins

Multiple heads, not a good evolutionary choice.

Multiple heads, not a good evolutionary choice.

Richard Dawkins spoke at University of Washington today as part of the book tour for his new book. I went to hear him speak because he is Richard Dawkins, I tend to agree with what he says (funny how that sometimes makes events more appealing) and the event was free. Free was a big part of it.

The format was about half an hour of selected readings from his book followed by questions and answers. The excerpts were good, nothing really compelling enough for me to buy the book; I still have not finished The God Delusion. The best part was the question and answer session. Instead of the normal line up to ask a question or write them in and submit them, all of the questions were texted in and selected from a pool of texts.

The best question of the evening was essentially “What is your proof of evolution elevator speech?”. I thought this is a really good question since I have been in situations where I need easy, fast and concrete proof of evolution. He would use either the geographic distribution of species or genetic relationship.s

Geographic distribution is how species are located around the world. All the marsupials in the Australia area, penguins in the antarctic but not arctic and alpacas are only in South America. If Noah’s arc was true then the distribution should be peaked in the middle east with little to no diversity on the edges. Not to mention the tough swim some animals would face.

Genetic relationships are bit tougher to explain quickly, it is the tracing of particular genes among species. From that tracing a family tree of life can be made, no matter which gene is traced the tree comes out the same every time. It might be more convincing (well it is) however it is a harder concept to grasp compared to penguins and kangaroos.
