Debunking the creationist myth that mutations don’t produce new and useful information

Genetic variation is a fundamental requirement for evolution, but many of the evolutionary mechanism (such as selection and genetic drift) actually remove variation from populations. Therefore, evolution is entirely reliant on the formation of new genetic information, and without it, … Continue reading
