    then you wrote it again.
    I have to look up this word: clade of dinos, clade of apes...
    Or your left ring finger is a bit out of control.

      I believe I recognize the syndrome. ;-)

      The modern conservative is engaged in one of man's oldest exercises in moral philosophy... the search for a superior moral justification for selfishness. - John Kenneth Galbraith

      Clade refers to a formally recognized taxon or evolutionary group of organisms. In current standard taxonomic practice in systematic biology, a group of organisms that all share a common ancestor can be formally names as a clade or taxon. Such a taxon would include the common ancestor and all of its descendants, whether living or extinct. Thus, all species are part of many clades in the taxonomic hierarchy. For example, humans are in the clade Homo, which is part of the clade Homininae (i.e., all species and genera of hominins share a common ancestor amongst themselves more recently than any do with the living chimps). Continuing out the hierarchy, humans are in the more inclusive clades Hominidae, Hominoidea, Primates, Mammalia, Synapsida, Tetrapoda, Amniota, Vertebrata, Chordata, and Metazoa. This is an incomplete list, but each clade listed is a part of all of the clades further on in the list with a part to whole relationship.
