Abstract
St. George Mivart (1827-1900) was a prolific writer on biological evolution and on its relevance to the Christian faith. His initial support for the evolutionary ideas put forward by Charles Darwin and Thomas Huxley would eventually turn into heavy criticism of these same ideas, evident in his 1871 book "On the Genesis of Species". This short paper critically evaluates the origins and development of his thinking that led to this book. It examines his paper "Difficulties of the Theory of Natural Selection", published in 1869, and argues that, even though some of his technical observations about the theory are outdated, some of his philosophical arguments are still relevant today.
