Evolutionary Science Reporting Battles Creationists

If creationism is so discredited as to not warrant any further discussion, some science writers are sure going out of their way to refute it.  Some recent examples: Eye of the Hydra:  Little sea creatures known as hydrae have light-sensitive molecules called opsins, reported Science Daily.  Scientists think the opsin proteins, which exist all over […]

Inner Ear More Complex than Thought

Another level of complexity has been added to the mystery of hearing.  Scientists at Massachusetts Institute of Technology (MIT) found that another membrane in the cochlea of the inner ear, once thought to be passive, is actively involved in transmitting sound waves to the hair cell receptors.  Their work was published in PNAS.1     […]

Whale Sonar: Necessity Is the Mother of Invention

Biosonar is a complex ability possessed by toothed whales and dolphins, bats and some birds.  It includes both the ability to produce signals and to process the echoes to locate prey.  How could such a system evolve?  Scientists at UC Berkeley proposed an answer.  The press release promised a developing story: Behind the sailor’s lore […]

Evolution Takes Credit

It may be more blessed to give than to receive, but evolution often just takes.

Fossil Gorilla Forces Hominid Ancestor Earlier

A set of gorilla teeth found in Ethiopia pushes the evolutionary story of a split between apes and humans back almost twice as far as previously thought.  Nature reported the fossil announcement that estimated the date of the teeth as 10.5-11 million years old.1  The prior estimate for a human-ape divergence was about 6 million. […]

Monkeys Prefer the Sound of Silence

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

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?

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: […]

Baby Frozen Mammoth Found Intact

The BBC News has a picture of a baby frozen mammoth that was found intact in northwest Siberia.  The article says it is one of the best-preserved frozen mammoths ever found, complete with eyes, fur, and trunk.  One investigator said, “In terms of its state of preservation, this is the world’s most valuable discovery” of […]

Elephant Trunk Inspires Robot Arm

Scientists are trying to imitate the smooth, supple movements of an elephant's trunk.

Chimp Altruism: Is it All True?

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

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?

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?

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

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 […]
