How are beaches originated? How long do they take to form?

Climatic effects of the impact and volcanism scenarios for the extinction of dinosaurs are investigated in a modelling paper.

The denial of miracles is a recent phenomenon based on how modernity has chosen to understand the workings of nature and what is possible in it. Belief in a personal God (theism), however, argues that through God’s actions, an event that is naturally impossible can be transformed into a real historical event.

Ancient Near Eastern views should be considered part of the history of the idea of evolution. The biblical Creation account, in describing the divine actions through which God actually brought the cosmos into existence, was likely deconstructing the alternative theories or speculations of origins available in the Ancient Near East. Consequently, the biblical narrative can be used as well to deconstruct contemporary cosmogonies and evolution. This article was originally published on Perspective Digest, v.24/3.

Why are we trying to find extraterrestrial intelligence, using our intelligence, while at the same time precluding the possibility that an intelligence was involved in the origin of our world?

How can some people be so certain about evolution, while others, with the same certainty, deny it? Part of the answer can, in broad terms, be boiled down to the difference between what is seen and what is not seen. More specifically, and in the context of evolution itself, this disparity arises from the difference between microevolution and macroevolution. What are these two concepts, and how does the difference between them help explain much of the controversy surrounding the theory of evolution? This article was published on the August 2019 issue of Signs of the Times.

A living being is more than the collection of the multitude of organic components of which it is made.

New observational data on the phenomenon of rapid bedrock erosion became recently available after the well documented events that affected the Oroville Dam in February 2017.

ARTICLE. In Utah and northern Arizona is a unique geological landscape feature, called the Grand Staircase. Imagine a staircase with each step a thousand feet or more high, and many miles wide. We will discuss hypotheses in regard to how this feature was formed. Published in Origins, n. 65.

With the scientific knowledge we currently have of nature, is it still reasonable to believe in miracles?

The hypothesis of a large meteorite impacting the surface of the Earth at the end of the Cretaceous was introduced almost four decades ago. In the ensuing years, the geologic community gathered a large body of data in support of this hypothesis, elevating it to the status of a universally accepted fact of Earth history. However, competing models and lively discussions are still unfolding over the dynamics and environmental consequences of this large impact.

Is Genesis History? asks a question that many Christians struggle with. Is the first book of the Bible comprised of pious myths? Is it an allegory designed to teach important lessons about God, but not actually a record of the history of life on Earth? Or is it a reliable record of events that actually occurred in the past? In other words, is Genesis the oldest book of history available today, one…

In a world drowning in information, there is an even stronger search for ultimate truth. It seems the information age expects each of us to sort out misleading advertisements, internet “facts”, and professionally perpetrated misinformation in our own attempts to determine what is true.

Iceland is a volcanic island in the North Atlantic Ocean, slightly below the Arctic Circle. The island is situated on a mid-ocean ridge at the boundary between the North American plate and the Eurasian plate. In Iceland, we find evidence of horizontal movements, in which two plates spread apart as the crust dilates with intrusion of new magma. Iceland, however, is also associated with a mantle plume (a narrow stem of upwelling of magma from deep in the mantle) that has maintained volcanism high and vigorous.

The rocks of the Earth are like pages of a history book containing information about the past. Geologists who enjoy reading this “book” have found that it consists of two “volumes:” the first, named Precambrian, is mostly devoid of macroscopic fossils. The second, named Phanerozoic, contains layers and sediments providing a rich archive of past forms of animal and vegetal life. The Phanerozoic “volume”…

This third part of a series on the Precambrian provides two perspectives suggested by creationists on how to interpret this portion of the rock record.

There is no simple clear definition of what life is. This is appropriate as life is a wonderful, complex, beautiful, enigmatic phenomenon that defies any effort to over-simplify it. Still, most people have no difficulty recognizing living things and differentiating them from non-living things.

The scientific method uses inductive reasoning to generate theories that explain data. Deductive reasoning is used to generate testable hypotheses that must be true if a theory is true. When the hypothesis is tested, it may fit well with the new data generated, thus supporting the theory (but not proving it true). If the hypothesis is inconsistent with data, then the theory is inconsistent with data…

There are still some rules that we have to follow if we are to do any science, including biology. The first is that empirical data is the authoritative test of all ideas in science.

Biology is the scientific study of life. But what is “science?” And what is “life?” Most of us use these words all the time and have a general idea of what we mean by them, however, it is common for scientists themselves to not have a clear understanding of what science is and this is not as surprising as it sounds. Philosophers of science struggle to define their own area of study, with different…
