ID 3.0

Today’s ID the Future is Part 2 of a recent live webinar with Eric Cassell fielding questions about his new book, Animal Algorithms: Evolution and the Mysterious Origin of Ingenious Instincts. He and host Casey Luskin explore the engineering wonders of web-spinning spiders and their extraordinary silk, and the challenge of transforming solitary insects into social insects (with their complex and interdependent caste systems) via a blind step-by-step evolutionary process, and the many thousands of genetic changes required. What does Cassell consider the best explanation? He invokes design theorist William Dembski’s work with No Free Lunch theorems to argue that blind processes are a no-go for explaining their origin. From there Luskin opens the webinar up to questions from the live audience. Have researchers tried to locate these algorithms in the DNA of the animals exhibiting complex programmed behaviors? Do any of the insects Cassell discusses use pheromones and, if so, how? What do biologists make of the apparently purposive nature of all these different kinds of complex programmed behaviors? Cassell fields these and other questions and says that more progress would be possible if not for the fact that so many scientists are infected with what he terms teleophobia — an unwillingness to recognize evidence of teleology and purpose in biology. Another question concerns examples of striking convergence among social insects and gifted animal navigators. Cassell argues that although the evolutionary community waves the term “convergent evolution” at such instances, they actually pose a powerful challenge to evolutionary theory.
