Most animal phyla, including those with soft bodies, appear in Cambrian sediments, in a pattern called the Cambrian Explosion. This pattern is exactly opposite of that predicted by Darwin's theory, but is readily explained in the context of creation and a global catastrophe. Published in Origins n. 53.
The subtribe Flaveriinae is a group in the sunflower family. This group of plants appears to have diversified from a single ancestral species after the flood. Published in Origins n. 52.
Trilobites are complex, elaborately segmented forms with jointed appendages and swimmerets, antennae, compound eyes, and cephalized, or head-to-tail, nervous systems.
Zoology and genetics are required courses for biology majors. Both subjects are usually structured around the theme of the theory of evolution. A careful examination of the scientific basis of these disciplines shows that the evolutionary framework doesn't fit with a lot of their fundamental aspects, however. Some of these topics even constitute strong evidence in favor of intelligent design.
The integration of Bible and science is an uphill work that requires careful reading of both the Bible and of scientific data. Because no other natural science has traveled so great a distance down an anti-biblical road, no other science requires this corrective procedure more than biology.
The complex and vitally essential ecology and biodiversity we find in nature today, at the top of the structural hierarchy of nature, suggest that many interacting organisms would have been required right from the beginning. Only a short-term creation would provide such ecosystem requirements.
As a scientist, I frequently find myself taking a polemic stance in defense of creationism. In doing this, I easily lose sight nature as a revealer of its Creator. It is a pleasant change to contemplate my field of scientific interest, looking for insight about the Creator.
One of the most interesting challenges in understanding Earth history is explanation of the order in the fossil record. Study of fossil patterns and trends should help improve our understanding of the underlying processes. Published in Origins v. 23, n. 2.

Pseudogenes are DNA sequences that resemble genes but do not appear to have a function. Similar pseudogenes in humans and chimps have been used to argue for common ancestry. However,if pseudogenes have a function in gene regulation the argument for common ancestry would be greatly weakened. Published in Origins v. 21, n. 2.
Pseudogenes are DNA sequences that resemble functional genes but seem to have no purpose. The presence of similar eta globin pseudogenes in humans and chimps has been used as an argument for common ancestry of the two species.
The philosophical context in which biology is presented can make an important difference in its meaning for the student. The philosophical worldview of the biblical Christian is quite different from that of the non-Christian; thus, the biology teacher may have a profound influence on the development of worldview by the student.
A review of the book, Rates of Evolution. Published from a symposium on evolution. Published in Origins v. 16, n. 2.
Most punctuated equilibria theories explain why proposed exceptions tend to be in the Upper Cenozoic. Punq Eq Creation Style, however, not only predicts the stasis and abrupt appearance of species, but it also predicts that exceptions will be found in the Upper Cenozoic among forminifera. Because of its greater explanatory power, PECS teoyr is superior to other PE theories. Published in Origins v. 16, n. 1.
Foraminifers exemplify many of the problems of fitting the fossil record into a short chronology, including thousands of named species and apparent evolutionary sequences. Any short-time creationist model must be able to explain these features. Published in Origins v. 15, n. 1.
Staining of chromosomes reveals a pattern of banding that may be used for comparisons of different species. Similar species typically have similar banding patterns, although there are exceptions. Banding patterns may be interpreted as hypotheses of relationship but are not, in themselves, sufficient to settle such questions. Published in Origins v. 13, n. 1.
Vitamin C is important in vertebrate physiology, but is acquired in different ways. Some mammals and perching birds do not synthesize it and must get it in their diet. Most other mammals and birds synthesize vitamin C, in their kidneys, the livers, or both. The pattern of synthesizing sometimes follows taxonomic patterns and sometimes not. Published in Origins v. 12, n. 2.
Bird and mammal footprints are most common in the same stratigraphic intervals where their body fossils are common. However, reptile and amphibian tracks are more common in stratigraphic layers lower than their body fossils. Published in Origins v. 9, n. 2.
Animals with high metabolic rates (birds and mammals) are capable of greater work output (speed, etc) but are restricted in size and shape in order to avoid losing too much body heat. Reptiles and amphibians have lower metabolic rates, and can survive at much smaller sizes and elongated shapes than birds or mammals. This is interpreted as a result of design for a diverse ecosystem. Published in Origins v. 9, n. 2.
A review of the book, Ecological Biogeography of Australia. An exhaustive review of the geology, flora nad fauna of Australia. Published in Origins v. 8, n. 2.
Coral reefs take time to grow, and some have questioned whether certain coral reefs could have grown to their present size in the time since the Flood. Evidence reported here indicates that rates of coral reef growth are quite variable, depending on water temperature, carbonate concentration, and depth. At the surface, ultraviolet light inhibits coral growth, so surficial measurements of coral growth are not a good basis for estimating rates of growth. Under ideal conditions, coral is capable of growing fast enough to produce present coral reefs in the time since the Flood. Published in Origins v. 6, n. 2.
