Devolution!
Holy crap! I just shed my feathers and wings and dropped down to Slimy Mollusc status in the Ecosystem!
Yet, an inspection shows that the number of links remains about the same.
I sure hope this is a temporary downgrade due to a system overhaul over there or something; I don't think I could take it, after my slow, steady climb from Crawly Amphibian up through Slithering Reptile to Flappy Bird. To drop down four categories would be a terrible blow to my self esteem.
