The diversity of birds on earth is remarkable. There are more than twice as many bird species alive today as there are mammal species.  A challenge for literal-day creationists is explaining how such diversity was either preserved during a global catastrophe not more than 4500 years ago or was formed after that event. Did Noah’s Ark hold... Continue Reading →
How can a population of organisms reproduce and over time become several hundred species each of which has its own menagerie of characteristics? This is a fundamental evolutionary question for which many different mechanisms have been proposed as solutions over the past 200 years.  With AiG's Ark Encounter nearing completion Ken Ham is about to put on display his...

What do giraffes, cows, sheep, antelope, pronghorn and deer have in common?  Foremost, they all share a specialized digestive system that includes a four-chambered stomach that allows them to obtain nutrients and energy from vegetation that is inaccessible to most mammals. This ability and other shared morphological traits are used by scientists to classify all...

As the strict young-earth creationists at Answers in Genesis work to complete their Ark Encounter "theme park," they have expended an impressive amount of energy organizing the millions of species of land animals alive today into a handful of small groups they call "baramins." Creationists insist that while adaptation or speciation within a particular "baramin" is observable (and, indeed, necessary in order to account for the present observed diversity of life), there is never any overlap between separate kinds. Unfortunately for the young-earth model, the push to minimize the number of animals riding on the Ark has exposed a major problem with this view.
I ended my previous article, Ken Ham's Darwinism, with the following observation: Ken Ham has fully embraced Post-Flood Rapid Evolution as a mechanism of creating the amazing variation we see today. As he slides further down the slippery slope into the rabbit hole of radical accelerated evolution he has now become, ironically, more accepting of naturalistic... Continue Reading →
Young life creationists, or baraminologists as they prefer to be called, have experienced a paradigm shift over the past three decades. Initially, young-life creationists (YLCs) made a point of identifying every possible unique characteristic of a species as the result of direct special creation and intelligent design. However, they are now increasingly embracing a model...

Dinosaurs play an important role in forming the public—and children's in particular—perception of the age of the Earth. I was reminded of this when I had the opportunity to attend two talks about dinosaurs both targeted at kids. The first was a presentation by Jack Horner of Jurassic Park fame but more importantly a researcher...

The largest collection of hominin bones ever found in Africa is causing massive waves in the anthropological world and beyond. When it was first announced, I wrote about how I thought some creationist organizations might respond to questions posed by hominin fossils and their geological setting (see: Bones of Contention: How Will Creationists Respond to...

In our tour of African stone artifact collections, we now travel to a remote portion of the Sahara Desert in southern Egypt. Stone artifacts are probably abundant in nearly all parts of northern Africa, but they are not easily found everywhere. The shifting sands of this forbidding desert have buried most of the evidence of...

I have been writing about the immense number of stone artifacts that are preserved in the sands, soil and rock layers of Africa in response to the young earth creationist's rejection of their existence or at least of their abundance. Â I was reminded that I had written about stone artifacts a few years ago that... Continue Reading →
The Nubian Desert, which encompasses 400,000 square kilometers of the eastern portion of the Sahara Desert, contains a rich assortment of stone tools and products of Stone Age industries. Scattered stones among the drifting dunes speak of a time long past during which this land was covered by grassy hills and ungulates, lions, and hyenas...

How different is the surface of Mars today compared to one thousand, a hundred thousand or a million years ago? The photo below was snapped by the Curiosity Rover which has spent several years trekking across an ancient lake-bed inside a large crater on Mars. It is a barren, forbidding but strangely familiar and beautiful...

Young earth creationists frequently speak of two kinds of science which they refer to as "origins" and "operational" science. These terms are possibly akin to what scientists may call "historical" and "experimental" science. What is this "origins" science and how does origins science play a role in the discussion of the Age of the Earth?...

A few weeks ago I was a scheduled to present several lectures as part of a course offered by Veritas Theological Seminary in Santa Ana, California. The course title was Scientific Apologetics: The Age of the Earth. The course was split 50/50 between speakers from Solid Rock Lectures including myself, and two prominent employees of the...

The Amazon basin isn't all a lush tropical forest.  In large portions of western Amazonian wet seasonally flooded grasslands - not trees - are the norm.  The upper branches of the Amazon River wind themselves across massive flood plains like snakes writhing across a sandy surface. One feature of these nearly featureless flat plains that...
