Everything has an origin.* Some stories of origins are relatively simple (eg. Niagara Falls) while others are much more complex (eg. the Grand Canyon). The study of origins is the study and reconstruction of past events. We have eyewitness accounts of some events from the past but mostly we use circumstantial evidence left behind as...

We all learned from an early age that earthworms are God's good gift to gardeners. They rework the soil and help to degrade leaf litter thus helping to make nutrients and water available to plant roots. Our appreciation of earthworms can be traced back to Charles Darwin who spent more than 40 years... Continue Reading →
There is a strange circular scar on the earth found amongst the meandering incised canyons of southeastern Utah. Called upheaval dome because it was originally thought to be the result of the slowing rising of a massive salt dome from below, this highly eroded structure has long been an oddity among the many spectacular sandstone...

What museum can you go to where you can see real dinosaur bones, you don't pay any fees, you can touch all the exhibits and there are no security cameras watching your every move (at least I don't think there are:-)? The answer is The Mill Canyon Dinosaur Trail near Moab, Utah. This outdoor "museum"... Continue Reading →
Southeastern Utah has an astounding amount of sedimentary rock on full display. Between our stays in Silverton Colorado and Moab Utah we made a trek through this area. One day hardly does this area justice but what we were able to see was amazing. The sedimentary layers are best seen in the gorge of the... Continue Reading →
Image you are living in 200 BC in the Middle East region and you come by the skull to the right as you plow your field or when you explore the local cave complex. What if you are wandering the desert in Egypt and happen upon the bones in the second figure. Or what about... Continue Reading →
In 2013 a remarkable DNA sequence was revealed by geneticists studying ancient DNA. It was the nearly complete genome extracted and decoded from the remains of a tooth from a horse preserved in permafrost sediments buried in the Yukon region in Alaska. This partially fossilized bone was estimated to be more than 500,000 years old. ... Continue Reading →
Yep, dinosaurs are known by more than just their bones. I have been reading quite a few research papers about dinosaurs as I prepare to write a long set of posts about Dr. Schweitzer and the significance of soft-tissue preservation in dinosaur bones. During this reading I got distracted by a discussion about dinosaur coprolites... Continue Reading →
Around Moab UT you can run down sand dunes and you can hike on rocks that were sand dunes in the past. You can take a face-plant on one, as my son did, and not get hurt but you better be very careful not to fall on the other. I recently spent a... Continue Reading →
Evaluating the state of creationism in the evangelical church today is a difficult task. Gallop polls suggest little changes among Americans regarding their views of origins but the generic nature of the questions make these results challenging to interpret. I have looked at web site traffic, publication records and other metrics of the reach... Continue Reading →
Dr. Jason Lisle of the Institute of Creation Research (ICR) gave a seminar entitled “Astronomy Reveals Creation” at this year’s PCA (Presbyterian Church in America) General Assembly. Some billed this as the young-earth follow-up to a seminar given at previous year's PCA assembly by Dr. Greg Davidson who presented evidence supportive of an ancient earth.... Continue Reading →
I’m sitting in the Boston Airport on my way to a conference at Gordon College but I have enough time for a natural history note while I wait for a colleague to arrive. On my flight from Ohio I read the last chapter of the Peter Harrison’s “The Fall of Man and the Foundations of... Continue Reading →
Family vacation with the Duffs always includes some geological sights. In 2007 we visited Prince Edward Island and had a wonderful time but the there just wasn't enough geology there to satisfy my curiosity so I took us on a 2 hour detour in Nova Scotia. After a lot of "are we there yets" and... Continue Reading →
Remember the meteor that exploded over Russia earlier this year? A 50 foot diameter object exploded 14 miles above the surface of the earth and created a shock wave that injured 1500 people and damaged more than 7000 buildings. Despite the drama, the lasting effects on the earth were minimal and only small pieces of the meteorite made it to the surface of the earth.
A recently published study is making news the last couple of days. It regards evidence obtained from remains of preserved bones of human scavenging and/or hunting practices. The site of the dig is a hillside in southern Kenya where, in less than an acre, more than 3700 fossils and more than 2000 artifacts have been recovered... Continue Reading →
