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).

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.

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.

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.

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…

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.

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.

If one accepts the evidence of the Cambrian Explosion at face value, the Darwinian theory of evolution is falsified. Unsurprisingly, evolutionists have tried to explain the Cambrian Explosion as an artifact, due to the incompleteness of the fossil record. However, there is an explanation for the Cambrian Explosion that is consistent with the data. An intelligent being could generate the genetic information needed for a diversity of body types in a short time.

There is significant scientific data consistent with the biblical record of history, EZT represents one scientific theory that seems to explain historical data from the Bible and data from paleontology thought to challenge the Biblical record.

EDITORIAL The geological column presents features that are difficult to explain, either from a secular or biblical viewpoint. Because the question is historical, scientific experiments are very limited in application to this question. More study is needed. Published in Origins, n. 61.

Traditional flood geology theory interprets much or all of the Phanerozoic part of the geologic column as formed during the one year of the biblical flood. Some geological and paleontological data are, in my opinion, difficult to explain in this theory. Wholistic geology endeavors to explain more of the earth science data while remaining true to a literal understanding of biblical creation and a global flood. Published in Origins, n. 61.
