One's perspective makes a big difference in how one sees the function of the human body. An evolutionist looks at the human body as a collection of organs pieced together by random processes selected for survival by the challenges of the environment, while the creationist sees marvelous evidence for design and information that shout evidence of an omniscient creator.

Evolution theoretically occurs when mutations result in new traits. Advantageous traits increase an organism’s chance of survival and reproduction, thus preserving the trait. A trait that is neutral may or may not be preserved. Numerous traits are selected because their advantages for survival lead to the evolution of new organs and new species according to the theory. This is called natural selection.

Can Nature Perform the Same Miracle MultipleTimes? Problems with Convergent Evolution

January, 2017

While I was studying chemistry in graduate school at the University of Texas, I befriended a physics graduate student, who was studying echolocation in bats in the hopes that the research might result in helpful technologies for blind people. One day he invited me to his lab to watch as he fed the bats. We entered a small room where dozens of bats eagerly waited for a dinner of yellow grub worms. Many of the bats were hanging from the ceiling but others were flying around us yet never touching us. I looked at one bat on the ceiling as he looked down at us. His mouth was open and his lips quivered as he rapidly rotated his head round and round. I was fascinated. The bat was using his echolocation capability, akin to sonar, to map out the environment. Bats would drop from the ceiling and fly around us then go for the food. My friend’s research revealed that different parts of the bat’s brain were activated depending on the frequency and direction of sound received.

For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, because that which is known about God is evident within them; for God made it evident to them. For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened. (Romans 1:18-21 New American Standard Bible [NASB])

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?

"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.

The transcription of information from DNA to mRNA is where non-coding DNA is encountered (Figure 2).
