    This bias is to biology only found in our experience. What if theres an alien physiology that ruins this argument.

      I’d argue centaur world is its own tree of life until proof exists that earth life and centaur world life had a common ancestor.

      No alien species counts as an animal taxinomically. A similar extraterrestrial ecosystem would likely result in reclassifications to add planet of greatest ancestral origin. Life seeders would make taxonomy even harder.
