A Strange Testament to an Ancient Earth: Bat Breath Causes Caves to Grow Larger

Can the act of breathing in a cave cause it to grow larger?  Limestone caves are usually formed by dissolution of limestone as the result of the interaction of carbon dioxide dissolved in water seeping through cracks in bedrock.   Typically this begins deep underground and as voids expand and reach the surface animals may enter […]

Dodging Darwin: How Ken Ham’s Ark Encounter is Slowly Embracing Evolution

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.

Mary Anning: Plesiosaurs, Pterosaurs and The Age Of Reptiles

What do you think of when someone mentions the Jurassic or Cretaceous ages? Most likely you will immediately think of dinosaurs and other large reptiles such as pterosaurs.  Maybe you think of the movie Jurassic Park and the dinosaurs and lush vegetation.   These periods are also known as the Age of the Reptiles and aptly so since many […]

Rewinding the Clock: An Asteroid Family History

You might think of the asteroid belt between Jupiter and Mars as a assortment of space junk floating randomly in space. There are millions of asteroids of which more than 100,000 have been measured and mapped by astronomers. But analysis of those asteroids has shown that there are groups of asteroids that are related to one another and are referred to family members

Kirkdale Cave Hyena Den: A Young Earth Puzzle Since 1821.

Imagine you live in northern England and you are out exploring and come upon a hidden cave entrance.  Upon climbing down into the cave you discover hundreds of bones belonging to large mammals.  At first you think the bones represent local animals since there are some deer, rabbits, weasels and wolves but soon it becomes clear […]

NH Notes: An Ode to Coprology

“Approach, approach, ingenuous youth,
and learn the fundamental truth:
The Noble science of Geology
Is founded firmly in Coprology.
For ever be the Saurians blest,
Who left us this diluvian test.
I claim a grand coronam lauri,
For these, Thesauri of the Sauri.”

William Buckland: Minister and Geologist Grappling with Fossil Feces, Deep Time and the Age of Reptiles

The Reverend William Buckland (1784-1856) was one of the last in a line of influential natural theologians following in the footsteps of John Ray (late 1600s) and William Paley (late 1700s).   I recently gave a seminar in which I explored a number of significant turning points (figure below) in the history of discovery of deep time and the awareness […]
