Skip Tilton served in the US Navy for six years as a sonar technician on board a nuclear submarine. He graduated from Bob Jones University with a B.A. in Bible and a minor in Pulpit Speech, and later earned a Master of Ministry degree. As you see, his credentials as a master of evolutionary biology are impeccable. They should be, for Tilton travels around giving speeches on how Darwin was wrong (such as introducing this one).
Tilton is a prominent member of Answers in Genesis (AiG) and Creation Ministries International, and he played a pivotal role in the construction of the AiG Creation Museum. You can download or listen to a talk about the creation of the “museum” here. I don’t necessarily recommend it, though.
Diagnosis: A minor cogwheel in the big, bizarre engine of denialism, Tilton seems to be dutifully doing his part without a hint of rationality, knowledge or connection to reality behind it. His personal impact is probably modest, but the organization he represents is a threat.
