Skip to comments.Sumatran Rhinos Are Living Fossils

His blog is in response to my comments on the living fossil issue, discussed here. I disagree with Naishs restrictive parameters, of course, as I see this more an issue of educational semantics influenced by zoology, not ruled by it. Darren Naishs approach is worthy of your attention and he has every right to his very informed point of view.
Needless to say, in this case, I was employing the living fossil definition that this rhino species is a living species/clade with many primitive characteristics in appearance, in which the species has many ancestral characteristics (plesiomorphies).
Most discussions of the Sumatran rhinoceros (Dicerorhinus) give credence to the notion that they display traits of and links to the Ice Age wooly rhinoceros (Coelodonta antiquitatis). [The Family Rhinocerotidae developed in the Late Eocene Epoch (55 to 36 million years ago) or Early Oligocene Epoch (36 to 22.5 million years ago) and spread across North America, Asia, Europe and Africa. The woolly rhinoceros appeared during the Mid-Pleistocene Epoch (about 500,000 years ago) in eastern Asia.] The Asian Rhino Specialist Group, for example, notes in their materials that the Sumatran is the last representative of the wooly rhino.
I will continue to use the living fossil phrase to highlight the points I wish to make, just as Charles Darwin, E. O. Wilson, Willy Ley, Bernard Heuvelmans, and Ivan T. Sanderson have before me.
I didn't know Arlen Specter was from Sumatra.
RINOs are fossils all right. Just look at Chafee, Specter, Snowe, Collins, etc.
With all the towns in Pennsylvania named after distant countries and cities, I'm sure that he hails from Sumatra, PA.
now, now I did not know this living fossil would turn into another RINO...
Irony off... :-)
Dang! You beat me to it.
Rhode Island has a Living Fossil in the Senate.
