Congratulations to the 37 winners of the Evolution & Christian Faith (ECF) grants competition! ECF is a new BioLogos program designed to support projects and network-building among scholars, church leaders, and parachurch organizations.
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.
The BioLogos Foundation explains to the findings of the Encyclopedia of DNA Elements (ENCODE) project and responds to the claims that its discoveries challenge the theory of evolution, especially regarding so-called "junk DNA".
In this excerpt from the book Delight in Creation: Scientists Share Their Work with the Church, astronomer Deborah Haarsma shares her excitement about recent findings about our universe from a Christian perspective.
Considering the immense popularity of "Darwin's finches", it is quite surprising to learn that Charles Darwin himself had very little to say about them. In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore.
In recent decades, scientists have discovered more about the beginnings of humanity. The fossil record shows a gradual transition over 5 million years ago from chimpanzee-size creatures to hominids with larger brains who walked on two legs. Later hominids used fire and stone tools and had brains as large as modern humans. Fossils of homo sapiens in east Africa date back nearly 200,000 years. Humans developed hearths for fire, stone points for spears and arrows, and cave paintings by 30,000 years ago. By 10,000 years ago, humans had spread throughout the globe. Genetic studies support the same picture. Humans share more DNA with chimpanzees than with any other animal, suggesting that humans and chimps share a relatively recent common ancestor. Also, the same defective genes appear in both humans and chimps, at the same locations in the genome—an observation difficult to explain except by common ancestry. Genetics also tells us that the human population today descended from more than two people. Evolution happens not to individuals but to populations, and the amount of genetic diversity in the gene pool today suggests that the human population was never smaller than several thousand individuals. Yet all humans, of all races, are descended from this group. Humanity is one family.
At a press conference on July 4, 2012, and with 99.99994% confidence (5 sigma), CERN announced the discovery of a particle consistent with that of a Higgs boson (a.k.a. “the God particle”). This is very exciting for elementary particle physicists. But what is the Higgs particle, and what is its meaning?
The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity? Is there actually any theological or religious significance in Higgs physics at all?
BioLogos is pleased to share excerpts from Karl Giberson’s book The Wonder of the Universe: Hints of God in a Fine-Tuned World. It presents a two-part argument: in the first section Giberson outlines the history of our understanding of the universe, emphasizing the reliability of our knowledge of its properties and its history. In particular he outlines the remarkable evidence of design. In part two of the book, however, he discusses the complexities of drawing inferences from the design of the universe, cautioning against arguments that fine-tuning of the universe proves the existence of God.
Baylor University Physicist Gerald Cleaver describes the changing state of our understanding of the cosmos and suggests ways that Christians can make theological sense of a theoretical Multiverse.
In this brief series (taken from a 2009 paper), Jennifer Wiseman uses an excerpt from the famous hymn “How Great Thou Art,” to explain why the study of God’s creation can lead Christ’s followers into meaningful worship and overcome the obstacles which impede true praise. Creation as encountered through our senses is pondered by our minds, which flows into wonder-filled songs from the soul. She further explains how knowledge of creation will help Christians to address the moral dilemmas of science, and she encourages all to see the process of scientific inquiry as a means to discover God’s truth.
Now that we have covered significant ground with respect to what various classes of pseudogenes are and how they arise, we are now able to properly evaluate antievolutionary arguments put forward in an attempt to discredit these lines of evidence for evolution.
The discovery of DNA has revolutionized our understanding of common descent, particularly in the past few decades. Mutated genes spread through populations over generations, leading to evolutionary change. In this podcast, we look at several examples of genetic evidence for evolution.
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.
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.
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.
I find that when many Christians think about the way God created our universe, they often bring a static expectation similar to what we bring to an ordinary statue. It’s as if we assume the physical realm were merely a rigid three-dimensional sculpture, immovable with time.
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.
