Paleontologists can get excited about fossils even if they are not dinosaurs, mammoths and hominids though this story has a Jurassic Park dino connection which helps. In this case several tiny fossil mosquitos had scientists abuzz in 2013. Fossils of mosquitoes are known from amber (fossilized tree sap) but are extremely rare in sedimentary rock...

The Amazon basin isn’t all a lush tropical forest. In large portions of western Amazonian wet seasonally flooded grasslands--not trees--are the norm. The upper branches of the Amazon River wind themselves across massive flood plains like snakes writhing across a sandy surface. One feature of these nearly featureless flat plains that has long puzzled... Continue Reading →
Young-earth creationists have been wrangling for decades over how to identify where the Flood/post-Flood boundary is to be found. I described the most popular hypotheses put forward by YECs in a recent post, Where is Noah's Flood in the Geological Column? I have also recorded a YouTube video based on this article. https://www.youtube.com/embed/7gEwLe6c3Wg There is... Continue Reading →
Young-earth creationists have a geological column problem that 50 years of research has yet to solve: where is the boundary between Flood deposits and post-Flood deposits?
Yes, multituberculates have something to say about the ongoing division among YECs about where to locate the Flood/post-Flood boundary in the geological column. Is that boundary to be found in the Quaternary, at the Cretaceous/Paleogene boundary or way down in the Pennsylvanian Period? These are the three primary models that YECs have proposed. The problem... Continue Reading →
Strike up a conversation about the age of the earth with nearly any group of evangelicals and you are sure to get a lively discussion.  There may be a young earth defender who will pull out some Ken Ham top-10 proofs of a young creation, some will claim to be agnostic on the topic while...

One of the great privileges of my job is that I get to participate on graduate student committees. Many times this allows me to get up close and personal with data sub-disciplines extend far from those of my particular expertise. You know that I have a fondness for fossils and the stories they tell. So...

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, Â I explained that the Toba volcano caldera produced the largest eruption in the past 100,000 years releasing an estimated 2800 cubic kilometers of... Continue Reading →
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. ... Continue Reading →
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...

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... Continue Reading →
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... Continue Reading →
Today, young-earth creationists are actively promoting a new model of the origin of the diversity of life on Earth. This speculative view borrows a number of elements found in any typical evolutionary biology textbook. For example, modern YECs claim that most and possibly all species alive today—except humans—are related to numerous other, though not all,... Continue Reading →
Everyone is an expert in something but they can’t be an expert in everything. At some point we all have to rely on the expertise of others to guide us through our lives. I am a biologist, however, the vastness of the field of biology leaves me in the position of deferring to the knowledge... Continue Reading →
In Egypt the Nile River Valley conceals a massive canyon that once was as deep and wide as the Grand Canyon in Arizona. We have explored the origins of this lost canyon in the previous posts.  We found that geologists attribute the origins of this massive canyon to the great drying up of the Mediterranean...
