Tiktaalik Not a Missing Link
December 4, 2008
Has all the colorful artwork of the fish-a-pod been for naught?  Three European biologists claim that Neil Shubin’s famous Tiktaalik fossil, supposedly of a fish evolving into a four-footed land dweller (see 05/03/2006, 11/13/2008) which has garnered iconic status in the media (01/16/2008), is not a missing link after all.     The situation is […]

Scientific Terms Can Obfuscate, Not Enlighten
October 29, 2008
When scientists classify things and use scientific terms, are they really shedding light on nature and natural history?  It’s possible they may just be glossing over their own ignorance, suggested three articles in Nature last week.  They underscore cases where subjective human conventions are falsely assumed to correlate with external realities.  They lead us to […]

Another Strange Chinese Fossil Found: Dinosaur or Bird?
October 22, 2008
Feathers and wings are among the most distinguishing characteristics of birds.  “Integumenary features” have been found on some dinosaur fossils, and true feathers have been found on some strange-looking extinct birds.  The news media often try to marry the two into a committed relationship using exaggerated artwork.  They have been found imagining feathers on fossils […]

Brain Candy as Tiger Milk
October 1, 2008
Observation: the human brain appears able to use lactate as fuel instead of glucose during strenuous exercise (see Science Daily).  Deduction: From an evolutionary perspective, the result of this study is a no-brainer.  Imagine what could have or did happen to all of the organisms that lost their wits along with their glucose when running […]

Did This Dino Have Bird Breath?
September 29, 2008
Birds are the only vertebrates with a unique one-way, flow-through breathing system that includes hollow bones.  Their unique respiratory system is part of the set of features that allows flying with its need for rapid metabolism.  Science news outlets are clucking wildly about another putative missing link between dinosaurs and birds: “Meat-eating dinosaur from Argentina […]
