The "RNA World" hypothesis for the origin of life is implausible for several reasons, among them the difficulty of producing RNA naturalistically, its relative instability in water over time, the problem of chirality, and the insufficiency of RNA to form a living cell. Published in Origins v. 20., n. 1.

It is unwarranted to assume a priori, as in the past that all upright petrified trees had grown in the place where they are now found. The transport of trees and their deposition in an erect stance is not as unlikely or as rare as might be expected. Upright fossil trees within the geological column are compatible with a Flood model. Actually, when all factors are considered, a catastrophe involving water and many floating trees is a more satisfactory explanation for their origin.

Early in the history of paleontology, a university professor with an interest in fossils was tricked into collecting fabricated objects as fossils and published a book illustrating these false productions. As a result, Johann Beringer was ridiculed unmercifully. This is not a good example to follow. We all make mistakes, and we should show compassion when we find errors in the work of others.

Evolution theory is based on competition and struggle for survival, but some animals act in a way that favors reproduction of other individuals and reduces their own competitive status. The theory of sociobiology wants to explain this altruistic behavior as having a genetic basis, so that individuals with the gene tend to help other individuals with the same gene,.This maintains the gene in the population. The idea that human behavior is genetically determined is controversial. Published in Origins v. 19, n. 2.

Microorganisms can exist in rocks several kilometers below the surface of the earth. Recently a number of reports indicate that these organisms are much more common than previously surmised and that vast regions of the underworld may be inhabited. Published in Origins v. 19, n. 2.

Several ideas have been proposed over the past two centuries to explain how organisms could have evolved through naturalistic processes. None of them seems viable, and it seems reasonable that creation should be considered as an explanation. Published in Origins v. 19, n. 1.

The current scientific picture of the origin of the Universe seems at odds with the Genesis account. Is this a serious problem for those who believe the latter to be reliable? Are there ways to harmonize the two? Or should we be looking for alternatives to the so-called Standard Model for the origin of the Universe? Published in Origins v. 19, n. 1.

A recent survey shows about 9% of the population accepts the viewpoint of naturalistic evolution, about 40% accept divinely guided evolution, about 47% accept a recent creation of humans, and about 4% registered they don't know. These results are nearly the same as a similar survey taken three years before. Published in Origins v. 18, n. 2.

The purpose of this essay is to examine the intellectual roots and the current status of the discussion concerning progressive creationism and to identify and evaluate eight theological implications of affirming the presence of death for millions of years prior to the appearance of humans in the geologic column.
