The Wonder and Blunder in Your Skull

Even when it goes awry, the brain wins an award of cosmic proportions, according to a veteran psychiatrist.

Animal Sin: What Does It Imply?

Some animals commit cruel or disgusting acts humans would consider immoral. What does this mean?

What SETI Guru Wants to Know

Seth Shostak, a SETI advocate, has two key questions for aliens.

Shrink Validity Is Shrinking

Should you trust the diagnosis of a psychiatrist? If it helps, individuals are free to choose. Behind the scenes, however, there are severe, deep-seated debates about whether psychiatrists understand disorders, let alone diagnose them properly.

Improbable Ape Speaks Randomly

It's not uncharitable to call someone an ape when he calls himself that.

Dark Matter as an Escape

Employing exotic unobservable entities such as dark matter may be an escape from scientific rigor in more ways than one.

Evolutionists Need to Mind Their Matters

To a Darwinian evolutionist, the mind is the product of unguided mutations and random environmental pressures acting on material forces. This raises questions about the mind and morals: do they have any validity? Evolutionists need to "mind" their matter. The following examples show how they try to justify these non-material entities arising from matter in motion.

Lamarckism: Dead but Useful

Lamarck's theory of evolution was supposed to have died in 1859 when Darwin published his theory of natural selection. Despite textbook depictions of Lamarckism as obsolete, Lamarckian language still surfaces from time to time, even in prestigious journals.

Evolution for Men and Women

Two recent entries in the evolution literature have application to one sex or the other.

We Became Human by Mistake

A new theme in human evolution is making the rounds. According to the story, a mistake led to the human brain, and the rest is history.

Planetary Radiometric Dates 1/3 Younger

The half-lives of radioactive isotopes may not be as well-known as thought. One decay rate frequently used to date solar system objects had to be adjusted down to 66% of its former assumed value, impacting theories of planet formation.

Questioning the Dino-Bird Hypothesis

The scientific consensus has pretty much declared it a fact of natural history that birds evolved from dinosaurs. One evolutionary professor remains a gadfly, though. He contests the evidence on which the hypothesis is based, and also believes his maverick position is growing.

Planet Theories vs. the Evidence

Planet theorists are putting up a valiant fight against new findings, but in some cases, the evidence seems to be winning.

Paradigm Shift: Impact Didn't Kill Dinosaurs

A new study casts doubt on whether asteroid impacts led to extinctions. It's based on re-interpreting geological evidence used to identify impacts. This finding, if sustained, would undermine the theory that an impact killed off the dinosaurs and a later impact led to the extinction of many large mammals. Even more significant, an overturn of the impact hypothesis would illustrate that scientists are capable of going off on wrong tangents for decades.

More Reasons to Doubt Scientific Pronouncements

It’s unsettling to hear scientists say that long-held beliefs might be wrong, but that’s the nature of science. Scientific “findings” are tentative, not absolute. Some see this as a strength of science, but unless actual progress is demonstrated, that strength is called into question. Recent news casts doubt on various scientific methods and beliefs that had been trusted for a long time.
