Homo naledi: An update
Two important papers were published in May 2017, warranting an update on the subject of Homo naledi.

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.
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.
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…
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…
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.
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 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.
This second part of a series on the Precambrian describes Precambrian rock exposures, as well as the atmosphere, climate, and Precambrian life. Many illustrative pictures are included, and design examples and creationist ideas are interspersed throughout.
This first section of a 3 parts series on the Precambrian summarizes the standard model for formation of the Universe, Solar System and Earth, Moon, oceans, continents, and plate tectonics. Brief references to the Universe, Sun, and Moon are included because what happens beyond Earth sets the stage for what happens on Earth during the Precambrian and in the Genesis 1 account.
This article provides an introduction to mineralogy and outline the different mineral categories, discusses some interesting features about minerals, describes the formation of minerals in different environments, and mentions some minerals referenced in the Bible.
The aim of this article is to use the example of Homo naledi to illustrate the distinction between data and interpretations, and to discuss some of the questions a biblical creationist might have in relation to this new discovery.
The world must have seemed like a big place to Helga Estby, a Norwegian woman who walked across America in the year 1896. Helga immigrated to the United States with her parents in 1871 at the age of 11. On May 5, 1896, at the age of nearly 36, Helga and her 18 year old daughter Clara set out to walk across the United States. They started from Mica Creek, in far eastern Washington state, and walked…
The philosophy of Naturalism dominates scientific thinking, for reasons that can be understood from review of the history of scientific thought. This article evaluates the nature and implications of Naturalism. Published in Origins, n. 64.
Texbooks describe the fossil record as the ‘best evidence’ for evolution. They claim that the fossil record proves evolution because there seems to be a succession from simpler to more complex life forms, and a succession from marine to terrestrial forms. Charles Darwin suggested that all life has a common ancestor. “All the organic beings which have ever lived on this earth may be descended from some…
The degree of importance of catastrophes for the geologic history of the earth has been the basis of a long scientific controversy that involves deep time questions.
