I dont recall it stating those 6 phases. I didn't believe that Darwin knew too much about the cosmos. Please post a site where can I read about that Opivy.
How are those theorized to be transitional fossils? Well the Sarcopterygii has both fish and amphibian like characteristics and Archaeopteryx has reptile and bird like characteristics. Other than that I'd be just repeating myself.
Mammals arent the only example, of course. Just look at at a timeline of the different animals. So far the hasn't been any mammals before reptiles, no reptiles before amphibians, no amphibians before fish, no multicellular organisms before unicellular organisms. You see a hierarchy going on? This is based on current records and observations.
