Two important papers were published in May 2017, warranting an update on the subject of Homo naledi.

The hypothesis of a large meteorite impacting the surface of the Earth at the end of the Cretaceous was introduced almost four decades ago. In the ensuing years, the geologic community gathered a large body of data in support of this hypothesis, elevating it to the status of a universally accepted fact of Earth history. However, competing models and lively discussions are still unfolding over the dynamics and environmental consequences of this large impact.

Is Genesis History? asks a question that many Christians struggle with. Is the first book of the Bible comprised of pious myths? Is it an allegory designed to teach important lessons about God, but not actually a record of the history of life on Earth? Or is it a reliable record of events that actually occurred in the past? In other words, is Genesis the oldest book of history available today, one…

Iceland is a volcanic island in the North Atlantic Ocean, slightly below the Arctic Circle. The island is situated on a mid-ocean ridge at the boundary between the North American plate and the Eurasian plate. In Iceland, we find evidence of horizontal movements, in which two plates spread apart as the crust dilates with intrusion of new magma. Iceland, however, is also associated with a mantle plume (a narrow stem of upwelling of magma from deep in the mantle) that has maintained volcanism high and vigorous.

Volcanic outcrops in the Galápagos Archipelago do not appear to provide the wealth of specimens found in other fossil-rich localities around the world. However, fossils are indeed present in the Galápagos Islands. This brief review addresses the where, what, when, and why of fossils in the Galápagos Islands and closes with a discussion of their potential contribution to the development of models on…

The term Cenozoic (or Cainozoic) means “recent life,” implying that the fossils encountered in these layers are more similar to modern species.

Few things in science evoke more interest in children than dinosaurs. Books, films, toys, etc. continue to fuel kids’ interest in the very alien world of our past, yet few Christians know how to respond to their children’s curiosity in a way that is both biblically sound and scientifically accurate. Although a full discussion of the fossils in Mesozoic rocks would require several volumes, a brief synopsis is presented here along with some creationist reflections for those who are interested – parents or otherwise.

The rocks of the Earth are like pages of a history book containing information about the past. Geologists who enjoy reading this “book” have found that it consists of two “volumes:” the first, named Precambrian, is mostly devoid of macroscopic fossils. The second, named Phanerozoic, contains layers and sediments providing a rich archive of past forms of animal and vegetal life. The Phanerozoic “volume”…

This third part of a series on the Precambrian provides two perspectives suggested by creationists on how to interpret this portion of the rock record.

The aim of this article is to use the example of Homo naledi to illustrate the distinction between data and interpretations, and to discuss some of the questions a biblical creationist might have in relation to this new discovery.

A general note of caution is necessary in the discussion of patterns in the fossil record. As with many other aspects of the natural world, the complexity that we find in this field of study tends to transcend our idealized categorizations.

Fossils are remains of organisms or traces of their activity preserved in the rock record. The scientific significance of fossils is truly remarkable, because they represent the only available archive of past forms of life. Through fossils, not only can we reconstruct the morphology of extinct creatures but also infer aspects of their ecology and environment. Fossils are also very relevant in discussions…

A collection of short commentaries on scientific papers published in 2015, covering topics such as phylogeny of moths, beak variations in species of Galapagos finches and scrub jays, functional synthetic chromosomes, horizontal gene transfer, Jurassic fossil snakes, stasis, trace fossils of swimming tetrapods, and habitat diversity in the fossil record. Published in Origins, n. 64.

Texbooks describe the fossil record as the ‘best evidence’ for evolution. They claim that the fossil record proves evolution because there seems to be a succession from simpler to more complex life forms, and a succession from marine to terrestrial forms. Charles Darwin suggested that all life has a common ancestor. “All the organic beings which have ever lived on this earth may be descended from some…

The degree of importance of catastrophes for the geologic history of the earth has been the basis of a long scientific controversy that involves deep time questions.

Biogeography is the study of the distributions of living organisms. Biogeographers seek to discover what historical and ecological factors explain why a species lives in one particular area but not in another area. This article examines how the flood might have influenced the present patterns of distributions of various types of living organisms.

There are only three known groups of volant vertebrates. Two are extant: birds and bats. The third group is completely extinct and known only from fossils: pterosaurs. Often referred to colloquially as “pterodactyls”, pterosaurs are a diverse group of reptiles totally foreign to our modern minds, yet in some ways they are incredibly familiar, resembling the dragons of folklore.

Lazarus species raise questions about how the geologic column formed. They are one good reason that we should be thinking about mechanisms other than deep time to account for the order we observe in the fossil record.

The first book of the Bible states that following a recent creation by God, there was an astonishing worldwide Flood. In that context, the Flood would have been responsible for most of the great fossil bearing layers of the earth. However, current scientific interpretations propose that these layers slowly accumulated over billions of years thus allocating more time for the slow gradual evolution of…

Glaciations are defined as periods of temperature reduction in the Earth's climate which result in the onset or expansion of continental and polar ice sheets and alpine glaciers. Does the geologic record preserve evidence for the occurrence and extent of former ice ages? What kind of information is used to make these inferences? The answer to these questions has the potential for influencing our models…
