Homo naledi: An update
Two important papers were published in May 2017, warranting an update on the subject of Homo naledi.
Would You Move to an Exoplanet?
If given the choice where in our Milky Way galaxy you would prefer to live, where would you go? To one of those newly-discovered extra-solar planets the media get enthusiastic about when water has been detected there?Before you answer these questions remember that, beyond the presence of water, many other conditions must be fulfilled before any planet can support the continued existence of life as-we-know-it,…
What Is the Evidence for a Large Asteroid Impact at the Cretaceous-Paleogene (K-Pg) Boundary?
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.
Organisms in Their Niche: Passive Modeling Clay or Problem-Solving Entities?
One person’s cultural background can bias their view about people from other cultures… even before they have ever met. Could people also have a bias about how they think about other creatures? It may even be possible that scientific culture could prejudice the way researchers see creature-environmental relations with the potential to bias whole research programs.
A Review of the Documentary Film “Is Genesis History?”
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…
Microbes, Symbiosis, and the Lesson of Interdependence
A very common reaction to the thought of “microbes” is a compelling desire to slather up in hand sanitizer! However, it is seldom realized that the greatest majority of microorganisms are at the very least not harmful, and at the most necessary for human life! Many aspects of microbial interaction with our environment allow it to be so perfect for humans. Some of these aspects include oxygen generation,…
The Great Search
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.
Stability of Organic Molecules: Lessons from Vitamin C
The stability of organic (carbon-based) molecules is an interesting and challenging topic as there are many different types of functional groups, molecular configurations, and molecular collisions to consider. Research on the stability of ascorbic acid (Vitamin C) and other vitamins demonstrates which factors to consider when it comes to the preservation of carbon-based molecules. Ascorbic acid…
Sabbath, Creation and Redemption
The Sabbath, a day set aside to honor the Creator, provides an important opportunity to review briefly two spiritual riches, among many, of the Genesis Creation narratives.
The Geological Story Told by Iceland
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.
Questions: Their Role in Discovery
When we are seeking answers, it matters a great deal what questions we ask. That seems obvious, but asking the right questions does not always happen automatically. And one of the important questions is “can I expect to know the answer to this question?”I am especially thinking of questions and answers relating to faith and science: questions about origins and geological history. First of all, consider…
Coping with Difficult, Unanswered, and Unanswerable Questions
Difficult, unanswered, and unanswerable questions are often catalysts for paradigm shifts in technology, medicine, and in personal and community value systems.Challenging questions important to Christian value systems are often about origins, evolution, pain and suffering, age of the earth, and various creation scenarios. Christian education has a responsibility to help individuals learn how to honestly…
Alpine Ophiolites: Remnants of a Lost Ocean
In 1813, French geologist Alexandre Brongniart published a paper on the mineralogical classification of rocks where he introduced the new name “ophiolite” for a suite of dark rocks rich in the mineral serpentine. The name was coined from the Greek words for “snake” and “rock,” which seemed fitting, given the smooth dark green appearance of ophiolites, vaguely reminiscent of snake-skin.
The Exceptional Properties of Water
There is one small molecule that makes our world unique and special. What is it? Water! Sure, other planets and moons in our solar system may have (or had) water and even more than Earth, but it is rare to find liquid water on the surface of a planet.
Fossils of the Galápagos: A Review with Implications for Creationist Models
Volcanic outcrops in the Galápagos Archipelago do not appear to provide the wealth of specimens found in other fossil-rich localities around the world. However, fossils are indeed present in the Galápagos Islands. This brief review addresses the where, what, when, and why of fossils in the Galápagos Islands and closes with a discussion of their potential contribution to the development of models on…
This point cannot be overestimated. Galileo wasn’t fighting against the Bible, but against an interpretation of the Bible dominated by the prevailing scientific dogma, which for centuries had been Aristotelianism.
The term Cenozoic (or Cainozoic) means “recent life,” implying that the fossils encountered in these layers are more similar to modern species.
Few things in science evoke more interest in children than dinosaurs. Books, films, toys, etc. continue to fuel kids’ interest in the very alien world of our past, yet few Christians know how to respond to their children’s curiosity in a way that is both biblically sound and scientifically accurate. Although a full discussion of the fossils in Mesozoic rocks would require several volumes, a brief synopsis is presented here along with some creationist reflections for those who are interested – parents or otherwise.
The Paleozoic Rock Record: A Broad Overview of Features and Trends
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”…
