Arnold, Michael

Michael Arnold is an evolutionary biologist whose work on genetic exchange mechanisms has implications for theological and philosophical discussions about divine action in nature. His book "Evolution through Genetic Exchange" (2006) demonstrates how horizontal gene transfer, hybridization, and other non-Darwinian mechanisms contribute to evolutionary change. While not explicitly theological, Arnold's research challenges simplistic notions of linear evolutionary progress that have been central to debates about teleology and design in nature. His findings complicate both creationist rejections of evolution and reductionist accounts that exclude purposiveness, suggesting that evolutionary processes are more complex and open-ended than previously understood. This work has been engaged by scholars exploring how divine action might operate through natural processes without violating scientific principles.
