A common argument leveled against the theory of evolution is that scientists have not been able to produce transitional fossils that show the change of one species into another. In this podcast, we address a common misconception about what transitional fossils actually are.
In the mid-seventeenth century, John Mayow conducted a series of experiments in which he showed that burning candles in bell jars consumed one-fifth of the enclosed air before extinguishing. Remarkably, mice placed in bell jars did exactly the same thing...
One of the challenges for discussing evolution within evangelical Christian circles is that there is widespread confusion about how evolution actually works. In this installment we explore how evolution is a theory in the scientific sense, how it is supported by converging lines of evidence, and how it can make accurate predictions about the natural world, using whale evolution as an example.
A common challenge to evolutionary theory is that while life does indeed change over time (what is known as microevolution), no one has ever seen one species evolve into another species (macroevolution).
Scholar and musician Jeff Warren addresses the questions of how music is meaningful, and where that meaning resides, by looking at the popular ideas that musical meaning is entirely subjective to the listener and that the meaning of music can be universal. He also explores the recent trend of attempting to explain music via neuroscience. Finally, he looks into the reasons why music continues to play such a critical role in the worshiping life of the Church.
This technical series, co-written by Darrel Falk and David Kerk, looks into the evidence for evolution in order to dispel doubts that people may have about this well-supported theory. They look at three things specifically: the separate methods which reveal of the age of the earth, the unfolding history of whale evolution, and finally the common trends of heart development in vertebrates.
Stephen Matheson presents common descent by evolution as the best explanation for the universal pattern found in tetrapod limbs. He discusses initially the evolution and development of limbs in specifically vertebrate tetrapods. He looks at the question of origins and further digs into amazing fossil discoveries. He then gives evidence of evolution from fish to tetrapods by discussing the similarities in the anatomy, development, and genetic systems associated with this amazingly common pattern in vertebrate appendages.
This blog series by Dennis Venema undertakes the task of clarifying numerous aspects of evolution that often become misconstrued by Christians. He first discusses the idea of speciation in a population over time, later applying it to the speciation process that occurred among hominids (human ancestors) which led to modern humans. He continues to support this idea by exploring so called “Mitochondrial Eve,”“Y Chromosome Adam” and other compositional clues of the human genome.
Many evolutionary critics have identified the Cambrian Explosion as a stumbling block to the theory of evolution, arguing that the “expected transitions between major invertebrate phyla are absent, and that the suddenness of their appearance in the fossil record demonstrates that evolutionary explanations are not viable.” Keith Miller argues that the Cambrian Explosion is not so problematic as these opponents claim after all.
As an evolutionary biologist I am fascinated by the emergence of cognitive abilities that make us so distinctive from other living species. There are, however, risks in making up evolutionary "just-so" stories to explain the origins of complex human beliefs.
In this video conversation, Jeff Schloss makes the observation that when we use the term “evolution”, it is not always exactly clear what we are actually discussing unless we denote the intended usage.
I am a fan of the blog "Jesus Creed." Recently it published an interesting post about the transition from fins to limbs as evidenced by fossils of an organism trapped in sediment 375 million years ago.
Fossils provide a unique view into the history of life by showing the forms and features of life in the past. Fossils tell us how species have changed across long periods of the Earth’s history. For instance, in 1998, scientists found a fossil showing an animal at the transition from sea creature to land creature. This tetrapod had a hand-like fin, confirming a prediction of evolutionary biology. Though the fossil record does not include every plant and animal that ever lived, it provides substantial evidence for the common descent of life via evolution. The fossil record is a remarkable gift for the study of nature.
Geologist Keith Miller examines the "Cambrian Explosion", a period of rapid evolutionary diversification approximately 575 million years ago, and whether it poses a challenge to evolutionary theory. From the June 2014 issue of Perspectives on Science and Christian Faith from the American Scientific Affiliation.
This two-part series highlights some of the most common misconceptions about evolution and some helpful responses to them.
How many times have you heard someone ask the question: "Have scientists ever actually observed the formation of a new species?" In this PNAS article, Peter and Rosemary Grant actually demonstrate the key events in the formation of a new species as it occurred before their very eyes.
Migration can often be a long and difficult journey for animals. For the bar-headed goose, migration often entails flights over the highest mountains in the world: the Himalayas.
A complex biological structure with many interacting parts might appear, at first glance, as if it were originally created in its present form with all its interlocking components fully formed and intact. It doesn’t seem possible that they developed step by step via biological evolution. In Darwin’s Black Box, Michael Behe introduces a term that he and other proponents of Intelligent Design use for this concept: irreducible complexity.
Evolution is the biological model for the history of life on Earth. While some consider evolution to be equivalent to atheism, BioLogos sees evolution as a description of how God created all life. Evolution refers to descent with modification. Small modifications occur at the genetic level (in DNA) with each generation, and these genetic changes can affect how the creature interacts with its environment. Over time, accumulation of these genetic changes can alter the characteristics of the whole population, and a new species appears. Major changes in life forms take place by the same mechanism but over even longer periods of time. All life today can be traced back to a common ancestor some 3.85 billion years ago.
