Trillions of stone artifacts cover the surface of the African continent. The product of the manufacturing of stone tools by hunters and gathers over long periods of time, these stone artifacts literally carpet the ground in some places in Egypt and Libya. Just how much Stone-Age produced rock could be strewn across the African continent? Trillions and trillions... Continue Reading →
News of evidence that Mars was once host to a volume of water equivalent of the Arctic ocean on Earth has been hitting the newswires. This might sound like new news but this is really just a more comprehensive analysis of work that has been ongoing for several years. Preliminary analysis had already suggested that...

In November of 2013, over 600 miles south of Tokyo, a volcanic eruption formed a new island. That new island continued to grow for over a year, eventually joining itself to the neighboring island of Nishino-shima, a volcanic island formed long ago. Today, volcanic activity continues to cause this new ocean-island to expand bringing it... Continue Reading →
Diatoms with their symmetrical highly-photogenic glass houses may get most of the attention but the foraminiferans (forams) present some formidable competition. In my recent article (Life in a Glass House) I revealed that the glass-house remains of diatoms are conspicuously absent from the bottom two-thirds of the geological column. This raised a rather uncomfortable question... Continue Reading →
Diatoms are single-celled organisms that live in almost any moist environment. They are found by the millions in a cup of sea water or a puddle in your back yard. They play a critical role in the environment as oxygen producers. But they are best known for their visually stunning homes constructed of glass. I... Continue Reading →
Eleven years into a three-month primary mission the Opportunity rover is still making discoveries on Mars. Talk about exceeding your specs! That is eleven years of observations of rocks, craters, sand dunes, weather conditions and the occasional glance into the skies to do some astronomy. To celebrate its 11th anniversary the rover has just climbed to... Continue Reading →
The physical and spiritual status of Neanderthals has been hotly debated since the first fossilize of bones were described from Neander Valley in Germany in 1856. Since that time bones from more than 400 Neanderthal individuals have been recovered over a large geographical range (fig 1). Hundreds of published studies on these bones, artifacts...

Evangelical Christianity, broadly defined, has seen a number of science and faith battles over the past 50 years. For most of those years the debate has focused on the age of the earth and the closely – though not universally - associated debate about the extent of Noah’s Flood. Today, the age of the Earth...

The landscape of science and faith discussions within conservative evangelical Christianity has shifted noticeably over the past 20 years. Vigorous debates over the meaning of the day of creation in Genesis 1 were common in the 1990s, resulting in study committee reports from conservative denominations like the Presbyterian Church in America, “Report of the Creation Study Committee”...

Hundreds of millions and possibly billions of stone artifacts sit just under parking lots and homes in Kathu, South Africa. A small sample of those artifacts were examined a few years ago in a vacant lot scheduled to be developed into a shopping plaza. A simple trench and pits dug in that lot revealed a...

A tidal wave of genomic information seems to wash up on shore each year. In 2014, an especially large wave - in those days long ago! - came ashore in the form of 45 entire genome sequences of birds. The relevance of these genomes and their hundreds of billions of letters of code representing all... Continue Reading →
Under nine feet of ice, frozen for 700 years, from DNA extracted from bits of caribou dung, a viral genome has been recovered and brought back to life. Don’t worry this isn’t a case of mad scientists resurrecting the black plague for nefarious purposes. This is the story of some inquisitive scientists investigating past environments...

The Mars Curiosity Rover continues to make its way through the basin of Gale Crater on Mars. I've provided periodical updates on its progress as it makes its way toward a large mountain in the center of the crater. Recently it has driven down almost 1000 feet to arrive at nearly the lowest elevation point... Continue Reading →
The Ebola virus has captured headlines around the world. One of the big questions that I see being asked frequently is - where did it come from? Does it have a recent origin or has the virus been with us for a long time but simply not recognized? Clearly it didn't come into existence in... Continue Reading →
While writing about the origins of the Dead Sea and Jordan Valley I was confronted once again with one of the most striking pieces of evidence for an ancient earth that I am aware of. Take a look at the figure below. This figure shows the smoking gun. Smoking gun evidence of what? That the earth's plates... Continue Reading →
