2. Worksheet #1 16. Species 17. Kingdom 18. Order 19. Species 20. Kingdom, Phylum, Class, Order 21. Mountain Lions and Domestic dogs. They are most related because they have more taxa in common. 22. Kingdom, Phylum 23. Class Amphibia 24. Primates (order), Hominidea (family), Homo (genus) 25. Rana temporaria is most related to green frogs (Rana clamitans). I know this because they share the same Genus, which means they also share the same family, order, class, phylum, and kingdom.
