Ecology, or environmental science, is multidisciplinary. As such, it allows ecology to be integrated with other disciplines. It also allows us to tie it to faith.

Many families of vertebrates appear to have reached South America from the north, as would be expected as they dispersed from the ark after the worldwide flood. These include all the widespread families. Many other families are restricted to South America. Their biogeographical history is unknown.

Review of the book, The Biotic Message: Evolution Versus Message Theory. Published in Origins v. 24, n. 1.

Frequently press reports describe the finding of bones and fossils of animals that existed millions of years ago. As a Bible-believing Christian and a creationist, my impression is that they can’t be that old. But I’m not sure. How can scientists determine the age of those specimens? How reliable are their dates?

The doctrine of Creation occupies an important place in Seventh-day Adventist message and mission. The reason for this is twofold: First, Adventists believe in a fiat Creation; and second, they are committed to the proclamation of the three angels’ message of Revelation 14.

Any credence given to the study of mathematics must recognize that God is the original mathematician. And though, through the ages, humankind has experimented to be able to draw conclusion in the areas of mathematics, God's laws are error-free and constant. His everlasting watch-care in the "natural" cyclic phenomena of this earth daily prove His mathematical supremacy. Galileo is remembered for having acknowledged that "mathematics is the language that God used to create the universe."

It must be emphasized that Chemistry, like any other area of scientific knowledge, is neither good nor bad, but like everything else that was marred by the entrance of sin, man's ability to manipulate his environment has led to misuse. Instead of giving in to technicism, where technology sets the agenda for life on planet Earth, the ethics of the Bible should be the basis on which we make decisions on the value of life and on the conduct of life.

One of the most interesting challenges in understanding Earth history is explanation of the order in the fossil record. Study of fossil patterns and trends should help improve our understanding of the underlying processes. Published in Origins v. 23, n. 2.

A review of the book, Darwin's Black Box. Published in Origins v. 23, n. 1.

Darwin's theory is in crisis. The academic ball is in its court. What will the Adventist ministry speak in response? The general community, for the time being at least, is listening.

A collection of short commentaries on scientific papers published in 1993-1994, covering such topics as parasite degeneration, convergence in diapsid reptiles, induced neoteny, genetic code, directed mutation in bacteria, radiohalos in a diamond, coelacanth phylogeny, marsupial phylogeny, origin of life, and fossil change in Jurassic rocks. Published in Origins v. 22, n. 1.

We need to develop ways to foster consciousness about the environment and a willingness to participate as good stewards of creation.

Pseudogenes are DNA sequences that resemble genes but do not appear to have a function. Similar pseudogenes in humans and chimps have been used to argue for common ancestry. However,if pseudogenes have a function in gene regulation the argument for common ancestry would be greatly weakened. Published in Origins v. 21, n. 2.

What is thought to be knowledge or information can usually be divided into two separate concepts: data and interpretation. Since data is subject to alternative interpretations, researchers must carefully distinguish between the information that constitutes the collected data and the "information" derived from the data that is presented as evidence in support of an hypothesis.
