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 →
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...

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 →
From a net pulled out of the ocean doesn't seem a likely place to find an ancient human fossil. But by scraping the bottom of the ocean,Taiwanese fishermen have been pulling up all sorts of unusual items in addition to their targeted prey. Like some trawlers off the cost of Great Britain these fishermen have...

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. Â 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...

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... Continue Reading →
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...

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 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 →
Does fossilization require rapid burial as the result of catastrophic global flooding? Literalist creationists would have us believe so for they point to the fossil record as being proof of a cataclysmic global flood.  Look a bit deeper though and you will find that creationists frequently concede there are thousands of exceptions to this general...

Moab will have yet another dinosaur attraction coming this fall. More than 200 reptilian footprints scattered over an area less than a football field have been uncovered after a resident discovered a few tracks while hiking. Dinosaur tracks are known from dozens of locations in this area but this site is unusual because of the...

A 15-foot-wide metal grate covers a hole in a bare rock outcrop in the high desert of the Bighorn Mountains of Wyoming. Beneath the grate lies a 80 foot vertical drop to into a cavern with no other exit. At the base of cavern situated below the hole in the ceiling are up to 30... Continue Reading →
Thousands of dinosaur footprints have been found on a steep mountain slope in Denali National Park in Alaska. These are not the first dinosaur tracks to be found in Denali but the size of the tracksite - at least 500 by 150 feet - and the exceptional preservation of the tracks makes this a notable...

Most of us remember our first life-like encounter with dinosaurs sitting in a theater watching Jurassic Park (1993). Although dinosaurs had been very popular in picture books for many years the vivid recreation of them on the screen rekindled a sense of awe of these amazing creatures of a past age. Today, movies with depictions...

There is a very recent form of fossil hunting that I have gotten to partake in to some small extent, and I can do it while sitting in front of a computer screen! With some computer skills and some knowledge of animal genomes it isn't difficult to join this hunt for fossils inside the genome of living organisms.
