In the 18th century, Linnaeus developed our first "library" classification system for life forms, the taxonomy:
In the 19th century, Darwin not only supposed that such a classification system evolved progressively from single cell to human, but carried out a study that suggested how such evolution might take place. Philosophers and popularizers ran with it; secular and religious people fought over it. Scientists have continued carrying out studies that have substantially modified and complicated the claims:
You're clearly sticking with a now outdated philosophical version of evolution, and Peder is trying to work with the philosophical implications of a more recent version of the scientific approach that considers newer evidence.
It may be too big a gap to bridge.
