The West Chester University Professor of Biology, Frank E. Fish, was vacationing along New England's coast frequented by magnificent humpbacked whales. While browsing in a gift shop one day he couldn't help but notice a gifted sculptor’s rendition of one of the splendid creatures and commented to the shop owner that the artist had put bumps on the wrong side of the pectoral fin. The bumps should be…

What is the utility of a fourth or a fifth of a wing stroke? Could any insect or bird get by with a wing that is a fraction of its normal size? Could it serve its purpose working at a reduced capacity? These questions are a challenge for those who accept Darwinian gradualism and adaptation. According to the Darwinian evolution theory, biological traits arise by small genetic variations steadily modifying…

Recently I flew to London on the new Boeing 787 Dreamliner. Despite what media hype might lead a Dreamliner passenger to expect, there were no fires on board and the experience wasn’t particularly different from what I’ve experienced on innumerable other flights. From my perspective, the seats were too small, too close together and too hard. That is not to say that there were not some differences,…

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 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.

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.

In the early development of the theory of evolution by natural selection, two men stand out as having played a central role: Charles Darwin and Alfred Wallace. Both men traveled widely and were keen observers of nature. For both men, visits to islands played an important role in developing their understanding of nature. Darwin's visit to the Galapagos Islands is of special interest.

The method of DNA-DNA hybridization has been applied to the relationships of birds, with some surprising results. The method is described and the results analyzed. While the results are quite interesting, there appear to be limits to the resolution of the method, and it seems inadvisable to depend upon this method alone when studying bird relationships. Published in Origins v. 14, 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.
