Giant Fossil Penguins Lived in Warm Waters
June 26, 2007
“Giant prehistoric penguins?  In Peru?” puzzled a reporter on Science Daily.  “It sounds more like something out of Hollywood than science,” but a fossil penguin you could look eye to eye with has been found that far north.  “We tend to think of penguins as being cold-adapted species,” said one of the discoverers,” but not […]

Crisis at Both Ends of Darwin’s Tree
June 21, 2007
Two assumptions about evolution – one about the earliest multicellular organisms and one about the rise of mammals – have run into trouble.  Eukarya sans Mechanista:  “In the absence of direct evidence, science should proceed cautiously with conjecture,” wisely advised Anthony Poole and David Penny in Nature.1  They scorned the researchers who glibly invent fables […]

Why Do Some Fruit Bats Have Color Vision?
June 12, 2007
One would think bats don’t need color, since most fly at night.  That’s what scientists thought, reported Max Planck Institute, until color-vision cones were found in some species.  Some species have two cone types, giving them bichromatic vision, and some have only one, making them effectively color blind.     Bats come in two orders: […]

Did Sponges Invent Nerves?
June 6, 2007
Scientists didn’t expect to find working neurons in a sea sponge, among the simplest of multicellular organisms.  Sponges lack internal organs and a nervous system.  Yet there they were, according to Science Daily, with synapses and apparent means of communication across them.     “This pushes back the origins of these genetic components of the […]

Did Walking Evolve in the Trees?
June 4, 2007
The news media are all echoing a report from Science1 that orangutan behavior in trees tells us something about the evolution of human bipedalism (see National Geographic, Fox News, and MSNBC News).  If this new view gains acceptance, it means the old iconic image of man emerging upright from a stooped-over ape posture (05/03/2007) is […]

Red Vision Produced Red Hair in Monkeys
May 27, 2007
A story circulating in the news media claims that as soon as monkeys evolved the ability to see red, they evolved red hair to look at.  Isn’t that the gist of a press release from Ohio University?  Science Daily thought so, and so did Live Science, which said, “A new study shows that apes first […]

Stupid Evolution Quote of the Week:  Design by Darwin
May 24, 2007
Can Darwin get credit for intelligently-planned research?  Apparently John Chaput thinks so.  A press release from the Biodesign Institute at Arizona State University states this: Nature, through the trial and error of evolution, has discovered a vast diversity of life from what can only presumed to have been a primordial pool of building blocks.  Inspired […]

Dino Feathers or Horsefeathers?
May 23, 2007
The much-touted feathers on certain dinosaurs may be nothing more than collagen fibers.  An article on ABC France says “Dinosaur ‘feathers’ are no such thing.”  Instead, it’s just decayed dermal collagen, like that found on sharks and reptiles.  A South African team came to this conclusion after analyzing the alleged feathers on Sinosauropteryx.     […]
