The Lake Malawi Sediment Chronometer and the Toba Super Eruption

One of the largest volcanic eruptions in earth’s history, the Toba super eruption has been a special interest to anthropologists and climatologists because of its potential impacts on past human populations.   I have explored the implications of the Toba eruption on human history in previous posts (See: The Toba Super Eruption: A Global Catastrophe that […]

The Toba Super Eruption, Polar Ice Cores, and Climate Change

I recently discussed how the catastrophic Toba super-eruption in Indonesia is a serious challenge to the young-earth model of earth’s history (The Toba Super Eruption: A Global Catastrophe that Creationists Ignore). Briefly,  I explained that the Toba volcano caldera produced the largest eruption in the past 100,000 years releasing an estimated 2800 cubic kilometers of […]

The Toba Super-Eruption: A Global Catastrophe that Young-Earth Creationists Ignore

Sudden catastrophic events are not unknown in earth’s history.  Large craters are evidence of past cosmic impacts and widespread layers of volcanic ash are a testimony to massive volcanic eruptions.  But when did these catastrophes occur and could they have influenced human history? Standard geological models place the largest catastrophic events far in the past.  […]

Institute for Creation Research Goes all-in on Denying the Reality of Natural Selection

A difference of opinion among creationist’ organizations about the origin of species and natural selection has been festering for a number of years and yesterday that dispute broke out into full view. The Institute for Creation Research (ICR) published a short article on their website extolling the virtues of Dr. Guliuzza’s Continuous Environmental Tracking (CET) […]

A Primer on Young-Earth Views of Speciation, Mutations and Natural Selection

How did the earth become populated by billions of species of living things? Conventional evolutionary biology provides an explanatory framework to answer that question. Intelligent Design advocates provide another as do Progressive Creationists (Old Earth Creationists).  But a large segment of the population looks to creation scientists (Young-earth creationists—YECs) to answer the question. How do […]

A Walk on the Beach Preserved in Stone–How Fossilized Turtle Tracks Refute Young-Earth Fossil Dogma 

Baby sea turtles emerge from their sandy nest and quickly make their way down the beach and into the sea. As they do so they leave tiny footprints in the sand, but the tracks are short-lived.  Blown away or destroyed by the next large wave, they are lost forever. Imagine the footprints you leave during […]

Young-Earth Creationism Leads the Short-Necked Okapi to Identify as a Giraffe

The Ark Encounter theme park in Kentucky is filled with signs and displays that promote young-earth interpretations of geology, astronomy, biology, archaeology and theology. I have critiqued many of these interpretations before (e.g. My Trip to the Ark Encounter and Depicting a Real Flood with Unrealistic Images). Today, I want to talk about one sign. […]

A Challenge to Ken Ham: Send Your Employees to Professional Science Conferences

Image credit: NASA Ames

How do scientists communicate with each other?  What are the latest research results? How can one learn about theories and how they are regarded by the scientific community? Where can you talk to scientists about their work?  A partial answer to all of these questions is:  scientific conferences.  It is possible to stay somewhat current […]

Ignoring the Plank: A Young-Earth Apologist Inadvertently Writes a Brilliant Critique of Young-Earth Creationism

How should a movement dedicated to science denial warn its adherents against the evils of science denial? Young-earth creationism finds itself faced with just this problem as some of its followers slip toward the flat-earth fringe. Answers in Genesis, the leading young-earth apologetics ministry, has responded by critiquing the flat-earth movement in a series of […]

Fossilized Rivers? The Exhumed Palaeochannels of Utah and Mars

Here is a puzzle:  Where can you stand on dry ground and look up to see a river channel above you? Yes, New Orleans is a good answer.   However, I’m talking about looking up 100 feet from a non man-made location.   There are many places on Earth and possibly on Mars where such […]

The Appearance of Age and the Origin of the Hawaiian Islands

What is the origin of the Hawaiian Islands?  The exploration of that question consumed my attention for several years.  At that time—way back in the 1990s—I was a post-doctoral researcher at Southern Illinois University sequencing chloroplast genes from holoparasitic plants. At the same time I discovered list-serve discussion groups, I was given creation science literature […]

Young-Earth Evolutionists? Talking about Hyper-speciation and Theological Implications

I recently attended the annual meeting of the American Scientific Affiliation held at Wheaton College.   About 300 professional scientists who are professing Christians had gathered to discuss a variety of topics related to science and faith.  Monday morning I delivered my presentation titled:  “Young Earth evolutionists? Adaptation of young-earth creationist models, and implication for the […]

An Armadillo Test Case of YEC Post-flood Dispersal Speed

Just how quickly can animals expand their geographical range?  Recently I expressed my skepticism about young-earth creationist’ claims that animals could depart an ark in the Middle East and migrated all the way to South America in just a few years (Glyptodonts, Armadillos and Ken Ham’s Hyper-Speciation Model).  Take the armadillos I wrote about.  There are […]

Glyptodonts, Armadillos and Ken Ham’s Hyper-Speciation Model

Armadillos are curious little animals but were all of them as small as they are today?  DNA extracted from a 12,000 year old bone of an extinct glyptodont the size of a small car revealed a genetic code that clearly places this huge animal inside the group (clade) of diverse animals we collectively call armadillos. These DNA results (see […]

How to Identify Pseudoscience: Lessons from Velikovsky and Catastrophism

Phrenology, essential oils, homeopathy, reflexology, ESP, astrology, creation science, climate change denial, blood-type diet, vaccinations cause autism, quantum computing, smoking causes cancer,  dinosaurs were killed by an asteroid impact, HIV causes AIDS, low-carb diet.  Which of the above would you classify as the products of good scientific research and which would you classify as pseudoscience?  […]
