TASC endeavors to show Christians and others in the Triangle area that the facts of science are consistent with the Biblical account of origins and inconsistent with the evolutionary worldview. 

Speciation: Any Examples Documented?

February, 2003

  It was interesting to find, while perusing a book on evolution, the rather candid admission of an evolutionist that there is no documented evidence of even a single species which arose from another species! Here is the quote:

"...I once asked the eloquent and personable Niles Eldredge whether he knew of any case in which the formation of a new species had been documented. I told him I'd be satisfied if his example were drawn from the laboratory, from the field, or from observations from the fossil record. He could muster only one good example: Theodosius Dobzhansky's experiments with Drosophila, the fruit fly. In this fascinating experiment, populations of fruit flies, bred at progressively hotter temperatures, became genetically separated. After two years or so the hot-bred ones could no longer produce fertile offspring with their cold-breeding brethren. "But," Eldredge quickly added, "That turned out to have something to do with a parasite!" Indeed, it was later discovered that the hot-breeding flies lacked an intracellular symbiotic bacterium found in the cold breeders. Eldredge dismissed this case as an observation of speciation because it entailed a microbial symbiosis! He had been taught, as we all have, that microbes are germs, and when you have germs, you have a disease, not a new species. And he had been taught that evolution through natural selection occurs by the gradual accumulation, over eons, of single gene mutations."

Cavemen—Missing Link?

February, 2003

Have scientists discovered evidence that humans are descended from ape-like ancestors? Are there real "missing link" fossils to prove this? Well, one of the reasons the term "missing link" is what it is, and includes the word missing, is that the evidence has long been—missing. Some have argued that this or that fossil is the "missing link", so we will examine a few of them.

There has been Piltdown Man, which was admittedly a hoax. The teeth were filed, and the bones chemically stained to alter the appearance. Then there was Nebraska Man, which was built out of a pig's tooth. This tooth was presented as evidence for evolution at the famous Scopes trial.

It is suspected that Neanderthal Man was simply a normal human with some medical problems—possibly arthritis, rickets, or acromegaly. Scientists now classify him as human.

But what about the drawings? We see pictures showing the "missing links" with their hairy bodies, their crouching gait, and so forth. Since this is what they looked like, weren't they obviously ancestors of humans? These pictures do show something between a man and an ape; however, the question is not whether the pictures show something between man and ape, but whether the actual creatures looked at all like the pictures. So, did they?

"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).
