One could ask the same question of genetics. When a science of genetics developed, it was incorporated into evolution. But that synthesis was 80 years after Darwin published "Origin."
When biogenesis has some good things to add to evolution, it will be incorporated into evolution. In the meantime, evolution is about change and the origin of diversity.
