A collection of short commentaries of scientific papers published in 2008, covering topics such as biogeography, sponge reefs, origin of life, human mutations, Arctic tree rings, fossil gecko. Published in Origins n. 63.
The idea that different types of organisms were created and commanded to reproduce "after their kinds" seems widely believed among creationists. It may therefore come as a surprise to many to learn the idea is not stated in the Bible. Published in Origins n. 60.
Within a Darwinian framework, this means that all genes shared by humans and sea urchins must have been present in a common ancestor shared sometime before Cambrian strata, which contain both chordate and echinoderm fossils, formed. Published in Origins n. 60.
The words kind and kinds that are mentioned in the Creation narrative of Genesis 1:21, 24, and 25. How are we to understand these terms in a modern context? How do they relate to current terms and classifications in biology?
How does one account for bird migrations? Why do they migrate at all? How do they know when it’s time to begin the long journey? What guides their flight path and direction? How do they know their destination, and how do they prepare for the trip?
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.
A collection of short commentaries on scientific papers published in 1993-1994, covering such topics as parasite degeneration, convergence in diapsid reptiles, induced neoteny, genetic code, directed mutation in bacteria, radiohalos in a diamond, coelacanth phylogeny, marsupial phylogeny, origin of life, and fossil change in Jurassic rocks. Published in Origins v. 22, n. 1.

Published in Origins v. 19, n. 2.
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.
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.
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.
Rabbits have a mechanism for re-processing food after it has fermented in the cecum. This is functionally equivalent to the cud-chewing of cattle, in which fermented food is redirected so that the nutrients produced by bacterial action can be utilized by the mammal. Published in Origins

A living mollusk from the eastern Pacific is similar to a Silurian fossil thought to be extinct for millions of years. This "living fossil" (a "Lazarus species") is a major discovery in mollucsan biology. Published in Origins v. 3, n. 1.
