::::::: ''How'' does that evidence support the hypothesis? Isn't it because of molecular, morphological, and biogegraphical ''similarities''? If not, then what ''is'' it? [[User:Philip J. Rayment|Philip J. Rayment]] 19:21, 26 March 2008 (EDT)

:::::::: This is really very tiresome. Cladistic studies are not based on 'similarties' that's called phentics. If we studied whales, sirenians and elephants by phenetics using the criteria above we might group whales and sirenians as most similar (thick outer skin, reduced limbs, marine lifestyle, blubber...) but if we use cladistics, which is about shared characters and the change of characters over time then we arrive at the relationships talked about above. And morpholigcal and molecular data arrive at the same position. If you still fail to understand the difference I'd invite you to read an introduction to cladistic methods.
