Guinea Pigs & Humans - We Have A Lot More In Common Than Evolutionists Would Think

July, 2005

Toxicologists like myself make a living out of evaluating the impact of chemical exposures and other insults on the health of laboratory animals (we can't test humans after all). Rats and mice, members of the evolutionary order Rodentia, make up a large majority of these experimental animals. Ken Boschert, a veterinarian with Washington University's division of comparative medicine and the operator of a Web site called Net Vet (netvet.wustl.edu/) estimates that 99 percent of experimental animals nowadays are rats and mice, which are small, cheap to feed, and reproduce quickly. Rats and mice are also believed to share a closer evolutionary lineage to humans than other non-primate mammals. Yet, another familiar mammal, guinea pigs, are in many ways toxicologically and genetically more like humans than rats, mice and even our closest evolutionary cousins, the chimpanzee. 1 This article will relate evidence from personal experiences and readings that suggest that guinea pigs are more likely to have shared a common designer than a common ancestor with humans.

Creation Resources and Evidences

April, 2005

Recently I was asked to give a talk on resources available on creation. I expanded the topic to include best evidences for creation. This article is based on that talk. For resources, I will discuss some of the major websites and organizations. Many of these will probably be familiar to you if you have been interested in creation science for a while. For best evidences, I will discuss scripture, the origin of the universe, the origin of life, the origin of species, empirical detection of intelligent causes, and the age of the earth.

Everlasting Life: Mission Impossible or the Great Commission?

March, 2005

Many of you will remember with me the epic TV series Mission Impossible which chronicled the adventures of the Impossible Mission Taskforce, a team of government spies and specialists who were assigned "impossible missions" by the unseen "Secretary". If not, you may have seen the more recent movie of the same title. If not, well, bear with me. I think you'll get the point. In the original series, the Team Leader (Dan Briggs the first season, then Jim Phelps the other six) was always given a mission, usually involving the impossible (hence the title) task of disarming an alarming situation within a time limit (inevitably by the end of the show). If you've read any recent news regarding the science of aging you may know that the government and other organizations have amassed similar teams of specialists today and tasked them with a similarly serious and seemingly impossible mission, to seek out and find scientific answers to the secret of everlasting life.

Where do viruses come from?

November, 2004

"For sheer numbers, no other ocean beings can match viruses. Thousands, sometimes even millions of these molecular parasites inhabit every drop of surface seawater, outnumbering even bacteria by 10 to 1... evidence that suggests that viruses are a powerful force in the sea, and one that determines how many plankton and ultimately how many fish, and even humans, an ocean ecosystem can support... viruses must have a profound influence on the WHY DID GOD CREATE VIRUSES?

A major line of reasoning used to argue against the creationist worldview is ‘why a benevolent God would create pathogenic organisms whose sole function seems to be to cause disease and suffering?

Given the current state of the United State's vaccine supply and the US Public Health Service's ominous forecasts for this flu season, this question is likely to be on the minds of more than just anti-creationists this year. Chiron, a major manufacturer of flu vaccine, will not be distributing any influenza vaccine this flu season, and on October 19, 2004, HHS Secretary Tommy G. Thompson announced to a worried public that, in order to ensure an ample supply of influenza vaccine for the most vulnerable Americans, people not in the priority categories should forgo getting the flu vaccine because it takes a shot away from someone who needs it more (http://hhs.gov/news/press/2004pres/20041019a.html).

"Junk" DNA as Evidence for Evolution?

January, 2003

"It is a capital mistake to theorize before you have all the evidence. It biases the judgment."-Sherlock Holmes in a Study of Scarlet

Back in the 1960s, scientists discovered sections of DNA that did not code for proteins. These non-coding DNA strands were assumed to be non-functional and were referred to as "junk" DNA, the presumed evolutionary remnants of ancestral organisms. 1 Almost 99% of human DNA is known to be non-coding.

A little background will facilitate discussion of non-coding DNA. Information in coding DNA sequences is transcribed into mRNA (Figure 1). mRNA exits the nucleus and attaches to ribosomes, the molecular machines that generate proteins. In the ribosome, the information in the mRNA is translated into an amino acid sequence to form a protein.
