Monkeys Prefer the Sound of Silence
August 5, 2007
Given a choice, chimpanzees choose silence over music.  The Random Samples page in Science1 mentioned experiments by scientists from MIT and Harvard where monkeys were given a choice of booths playing a flute lullaby, a Mozart concerto, techno-rock, and silence.  Between the musical booths, “The monkeys spent an average of about two-thirds of their time […]

Motorized Ears Give Mammals Acoustic Acuity
July 31, 2007
f=”crev03.htm#amazing11″>03/27/2001), we reported on the discovery of prestin, a motor protein that acts as an amplifier in the inner ear.  One of the fastest-acting molecular motors known (02/21/2002), prestin works by stiffening the rod-shaped cell body with its cilia.  Somehow, the action of this motor protein amplifies hearing in mammalian ears by several orders of […]

But Is It Evolution?
July 14, 2007
Every week the news media cheerfully present the latest finding that is claimed to be evidence for evolution.  The following recent examples, though, might leave a perceptive reader wondering, “What’s Darwin got to do with it?” Slow? No!:  If you thought evolution was a gradual process too slow to watch, get a load of this: […]

Chimp Altruism: Is it All True?
June 27, 2007
Humans are the only inhabitants of earth that are masters of true altruism: helping others with no thought of reward.  Previous experiments had shown that chimpanzees lack this trait.  Given an opportunity to help another chimp get a banana, they showed no pattern of charity.  New experiments by researchers at the Max Planck Institute for […]

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 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 […]

Batting for Stupid Evolution Quote of the Week
May 18, 2007
National Geographic reported that bats are master flyers, whose aerodynamic skills outperform birds.1  They also have an exquisitely refined sonar sense that allows them to discern detail as fine as a fish fin sticking out of the water.  Coupled with aerobatics and see-in-the-dark sonar, a bat can swoop down and catch the fish right out […]

Time for Mammals
April 25, 2007
Three recent news stories about mammals involve time.  Does nature time things well, or do evolutionists tell swell things about time?  Time will tell. Placental mammals – Watch those assumptions:  How much can you trust dates that can vary by 50%?  A report in Science Daily says the new “consensus” date for the appearance of […]

Cave Chimps Suggest Cave Men
April 11, 2007
Some chimpanzees have been found in Senegal using caves for shelter from the heat.  Jill Pruetz (Iowa State) took note of this and is publishing a paper about it in Primates.  National Geographic speculated that this sheds light on human origins: The adaptations of savanna chimpanzees are particularly interesting to researchers because early humans are […]

Preprocessed Sound Produces Tone Map in the Brain
April 6, 2007
Most of us know that our ears involve three domains: the outer ear, the middle ear, and the inner ear.  We learned in school how the eardrum transmits the sound to tiny bones that transmit it to fluid in the cochlea, which stimulates hair cells that send the impulses down the auditory nerve to the […]

Evolution to the Rescue for Abused Ape
April 5, 2007
The UK Guardian reports that Austrian courts are being asked to grant human status to an ape to allow it to sue a company for importing it into Austria for medical research.  In 1999, New Zealand granted “non-human hominid” status to apes to protect them from maltreatment, but this case attempts to give full human […]
