I see zero problem with having no children and studying evolution. You don’t need to become superconductive to study the physics of superconductivity. You don’t need to become infected by every virus to study virology, and you definietly don’t need to be a virus to be a good virologist. So why would you need to pass on your genes to study evolution?
