Plants’ International Travel Upsets Evolutionary Idea

They may be rooted in soil, but plants really get around.  Some of them make it around the world.  One example has upset a long-believed evolutionary idea.     First of all, plants have a social life.  National Geographic published a story about how plants socialize and communicate.  “Plants have family values, too, it seems, […]

Genome Complexity Unveiled: No Junk, Only Function

Any remaining doubts that the idea of “junk DNA” has itself been junked should vanish under the latest findings about genome complexity.  A number of recent news stories have revealed astonishing levels of regulation and organization in the non-coding regions of DNA.  It turns out that genes are not the only interesting things in the […]

Imaginary Dinosaur Feathers Found – Again!

Last year, we reported that imaginary feathers had been found on a dinosaur fossil (see 02/08/2006).  Now, more imaginary feathers have turned up.  This turkey was big, too: the dinosaur plumed in the imaginary feathers stood almost 12 feet tall.  Everyone’s talking about it: Fox News, MSNBC News and Science News among others.  National Geographic […]

Color-Blind Cephalopods Perform Colorful Camouflage Tricks

Roger Hanlon has studied octopi, squid and cuttlefish for decades.  He stands in awe of their ability to camouflage themselves.  In a Primer article for Current Biology,1 he detailed some of their sleight-of-skin magic tricks.     His article has frames from a movie clip that show an octopus changing its skin from plain to […]

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 […]

Origin of Multicellularity: Back to the Drawing Board

Micro-RNAs have been found in green algae.  So?  What’s the big deal?  If you read the statements in Nature,1 it sounds like evolutionary biologists consider it a big, bad deal: The discovery, made independently by two labs, dismantles the popular theory that the regulatory role of microRNAs in gene expression is tied to the evolution […]

Resisting Science, or Resisting Purposelessness?

Why do so many adults “resist science”?, asked Yale psychologists Paul Bloom and Deena Skolnick Weisberg in an essay on The Edge.  They argued that childhood common sense impressions lead to a teleological view of the world.  These impressions conflict with evolutionary ideas presented at school, but are reinforced by religious authorities.  The job of […]

Science Is for the Birds

Birds, with all their variety and functionality, are a never-ending source of study for scientists.  Here are some recent feathery findings: Memory masters:  Scrub jays are like us: they can plan ahead, regardless of mood.  Current Biology did a study that proved these common western birds can cache tomorrow’s breakfast regardless of their motivational state.  […]

Can Morality Be Evolutionized?

A psychologist at the University of Virginia is probing the evolutionary origins of morality: [Jonathan] Haidt shows how evolutionary, neurological and social-psychological insights are being synthesized in support of three principles: 1) Intuitive primacy, which says that human emotions and gut feelings generally drive our moral judgments; 2) Moral thinking if [sic] for social doing, […]

New Theory for Introns: Mutation Sponges

When you don’t know where damage will occur, it makes sense to spread the assets around.  Scientists from City of Hope Medical Center (a cancer care and research institute) have a new idea about introns, those regions of DNA “junk“ between the more interesting exons (parts of genes).  Perhaps the introns are mutation sponges.   […]

More Optical Design in Eye Retina Than Seen Before

For decades, evolutionists have used the vertebrate retina as an example of poor design (dysteleology).  They have mocked how any designer could have been so unintelligent as to get the wiring backwards – with the photoreceptors behind a jumble of light-scattering cells.  Creationists have countered that despite the arrangement, it works well.1  Now, they may […]

Earliest Comb Jelly Fossil Looks Modern

One would think that a paper listed in the category “Evolution” would include supporting evidence that evolution had occurred, but a new Evolution paper in PNAS provides more arguments against it than for it.1  An international team studying early Cambrian fossil beds in China found a comb jelly embryo essentially identical to those alive today.  […]

Stupid Evolution Quote of the Week:  The Evolution of Shopper’s Arm

This week’s prize goes to the Society for Experimental Biology, which, according to EurekAlert, said this in a press release: The next time you are struggling to carry your bags home from the supermarket just remember that this could, in fact, be the reason you are able to walk upright on two legs at all!  […]

New Dinos Found; What Do They Mean?

There is often a wide gap between the bones that are found and the stories that are told about them.  As new dinosaur bones come to light, some reporters cannot resist imagining all kinds of things about their lifestyles.  Here are two recent examples.  As a bonus, we’ll add a non-dinosaur reptile story or two. […]

Questions to Ask a Reductionist Neurobiologist

Can the totality of the brain be described in terms of its neurons?  Is consciousness an artifact of the movement of signals in the brain?  Can the complexity of the brain be described in terms of its evolutionary history?  Does the hardware define the software that runs on it? Gy�rgy Buzs�ki attempted to address these questions […]
