Climatic effects of the impact and volcanism scenarios for the extinction of dinosaurs are investigated in a modelling paper.
A Cambrian fossil worm shows only minor differences from species still living, an example of family stasis.
Darwin saw evolution as a slow and steady process with species gradually transforming into new species over long time. He thought that the fossil record should provide evidence for his theory. However, the needed evidence proved to be elusive.
The "Cambrian explosion" is a term used to describe the abrupt appearance in the fossil record of major animal phyla, without intermediate forms in lower layers. This pattern of abrupt appearance can be observed for many groups of organisms, including crinoids (sea lilies).
Ancient Near Eastern views should be considered part of the history of the idea of evolution. The biblical Creation account, in describing the divine actions through which God actually brought the cosmos into existence, was likely deconstructing the alternative theories or speculations of origins available in the Ancient Near East. Consequently, the biblical narrative can be used as well to deconstruct contemporary cosmogonies and evolution. This article was originally published on Perspective Digest, v.24/3.
The abrupt appearance of trilobites in Cambrian strata and their absence in Precambrian sediments is a real feature of the rock record and not due to failure of preservation in Precambrian rocks.
A newly described Cambrian locality in China has added more than 50 new species to our knowledge.
The study of fossils and the associated rocks in which they are preserved gives us information about ancient conditions in which organisms lived, called paleoenvironments, and the pathways leading to their fossilization.
Confirmation that fathers may sometimes pass mitochondrial DNA to their children violates the assumptions used to calculate the age of the most recent female common ancestor of all living humans. Published in Origins v. 21, n. 2.
EDITORIAL. Those who study historical topics such as origins often face questions for which no easy answers are evident. Nevertheless, there are some things that can be known, and these should not be overlooked. Published in Origins, n. 65.
Two important papers were published in May 2017, warranting an update on the subject of Homo naledi.
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…
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…

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.
