You may or may not be aware that one of my research interests is the response of Evangelical and Fundamentalist Christians to the theory of evolution. It was actually my whole master’s thesis.
So in studying how Christians have tended to oppose the teaching of Darwinian evolution (in which all living species are descended from a single common ancestor through natural selection and genetic mutation, among other processes) over the past century, one of the key arguments they’ve used against it is the existence of the Cambrian Explosion.
The argument is typically made this way: “Darwinism argues that all of life has gradually evolved from a single common ancestor, but they can’t explain the Cambrian Explosion, where the fossil record goes from basically no living species to an incredible amount of diversity in a very short time.”
This argument had two prongs: One was negative – the explosion is something evolution cannot explain; therefore, it chips at the foundation of support for the theory – and one was positive: The explosion is the fossil record’s evidence of God’s special creation of a limited number of “kinds” that then evolved to the current diversity of life. This idea, let’s call it young earth evolutionism, is still propagated by Ken Ham, founder of the Creation Museum and Ark Experience, as scientific creationism.
Here are some examples from my research: Continue reading The Fizzling of the Cambrian – and Creationism
