Milankovitch Cycles Indistinguishable from Randomness
June 2, 2009
A claim has often been made by geologists that the rock sediments record cyclical changes in Earth’s orbit.  Milankovitch cycles, named for the man who analyzed them, are a set of regular periodic changes to the orbital eccentricity, obliquity, and axial precession of the Earth over tens and hundreds of thousands of years.  These subtle […]

Hominids, Homonyms, and Homo sapiens
May 27, 2009
How’s the story of human evolution hanging together these days?  There’s no better place to look than the Annual Review of Earth and Planetary Sciences.  In the yearly issue released this month, Ian Tattersall and Jeffrey Schwartz gave a pretty thorough overview of the “Evolution of the Genus Homo.”1  Their account is fraught with controversy, […]

Building Planets: Can’t Make Them, But Hurry
May 21, 2009
Constructing planets is a delicate business.  Trying to get tiny bits of dust to join up into balls has never been found to work.  It has to work fast, though, because unless the whole planet clears its dust lane, it will be dragged into the star in short order.  It seems you can’t get there […]

Early Man IQ: Et Tu, Brute?
May 12, 2009
Anthropologists are receiving a jolt about the intelligence of early man.  Long before the cave paintings showed our forebears exercising art appreciation, new findings suggest they were gifted individuals, not brutes.     The first report was about manufactured beads dated older than 82,000 years.  Science Daily said, “The shells are currently at the centre […]

State of the Moon Titan Addressed
May 6, 2009
Each May, a series of articles on major topics of geological interest, written by leading experts in the field, is published in the Annual Review of Earth and Planetary Sciences.  This year’s issue includes a treatise on Titan, the large moon of Saturn, written by the two titans of Titan science, Jonathan Lunine and Ralph […]

Dinosaur Blood Protein, Cells Recovered
April 30, 2009
It’s official: soft tissue, including blood vessel proteins and structures resembling cells, have been recovered from dinosaur bone.  Mary Schweitzer’s amazing claim in 2005 (03/24/2005) was subsequently disputed as possible contamination from biofilms (07/30/2008).  Now, Schweitzer and her team took exceptional precautions to avoid contamination by excavating hadrosaur bone from sandstone said to be 80 […]

Are Secular Geologists Ready to Consider a Global Flood?
April 30, 2009
Everyone knows the Bible tells the story of a global flood in Noah’s day.  Creation scientists argue that its effects would have left visible evidence today – including most of the sedimentary layers and most of the fossil record.  Secular geologists have laughed off this story since the 18th century as nothing but myth, of […]

The Long Precambrian Fuse Gets Longer
April 28, 2009
Why did complex multicellular life explode on the scene some 550 million years ago?  That’s mystery enough, but finding complex single-celled life a billion years earlier makes it worse.  A new paper evaluated claims of Cambrian-like fossils from India dated 1.6 billion years old in the evolutionary timeline.  It did not explain the Cambrian explosion, […]

Mooning the Public: Life Sells
April 27, 2009
Advertisers have known for a long time that sex sells.  That’s why ads often include a scantily-clad woman standing next to the pickup truck for sale.  It seems that in planetary science, life sells.  An icy moon can be a pretty dull thing, but announce that there might be life there, and eye appeal jumps.  […]

Did Early Man Have a Soul?
April 8, 2009
Some recent discoveries are surprising paleoanthropologists by much some early ancestors seem – well, human.  We’re talking about ancestors half a million years old in the evolutionary scheme.  They were supposed to be prior to Homo sapiens and the Neanderthals, but they seem to exhibit intelligence and compassion.     A report on New Scientist […]

Early Large Galaxies Stun Cosmologists
April 2, 2009
Cosmology has a kind of Cambrian Explosion of its own to grapple with.  Contrary to expectations, some of the earliest galaxies appear as large as current ones, if not larger.  Astronomers, using the Subaru telescope in Hawaii, examined five galaxy clusters with ages estimated at 5 billion years after the Big Bang.  Statements in a […]

Peking Man Ages 200,000 Years
March 16, 2009
Dates for Chinese fossils of Homo erectus have been pushed back 200,000 years to 780,000 years before the present, reported Live Science.  The report is based on a paper in Nature by scientists who used cosmogenic nuclide dating methods for the first time.1  Ciochon and Bettis, in the same issue of Nature,2 said the report […]

Permian Extinction: The Origin of Specious Geological Events
March 9, 2009
The Permian extinction – one of the most dramatic events in the history of life on Earth, in which some 90% of species went extinct – lay people assume scientists can back up this story with evidence from geology and fossils, but where is it?  Whatever happened at the prime site in South Africa, from […]

Darwin’s Wrong Turn in Argentina
February 12, 2009
When the Beagle was sailing the coast of Argentina in 1834, it stopped at the mouth of the Santa Cruz River.  25-year-old Charles Darwin, who had been reading Lyell’s Principles of Geology, got out and explored the area on foot as the crew made camp on the cliffs.  Darwin was impressed by the six-mile-wide canyon […]
