The bottom line is, armed with a fertile imagination and phantom ancestry "branches", a Darwinist can fit any creature at all into a "nested hierarchy" - even a platypus. Darwinists justify this farce by adopting the a priori position that all life is related, therefore every creature must somehow fit into the "bush of life".
Um, you do know how babies are made, right?
Life comes from life. It
has to be related.
