Series: Decoding ENCODE (8 entries)
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".
Series: Understanding Evolution: Is There “Junk” in Your Genome? (5 entries)
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 on “junk DNA”, we explore how genomics can be employed to test for non-functional sequences by comparing sequences between related organisms.
Where is the Genetic 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.
Series: Evidences for Evolution (7 entries)
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.
Series: Signature in the Pseudogenes (3 entries)
This brief series explains the significance of pseudogenes. Darrel Falk and Dennis Venema demonstrate how the theory of common descent provides a fine framework in which to interpret the existence of these once-functional genes. They also discuss the relationship of various primates and other mammals based on shared pseudogenes. The evidence in support of evolutionary theory, they argue, is compelling when examining the rich history disclosed in the DNA of every organism.
Signature in the Synteny
In some ways, comparing the DNA sequence between related organisms is like reading alternative history novels. The hypothesis of common ancestry between similar organisms makes a very straightforward prediction about their genomes...
Evidence for Evolution in the Mouths of Birds
A friend tells me the most important task for The BioLogos Forum is to present evidence of evolution in ways people without a biology background can understand.
Evolution and Christian Faith Grantees Announced
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.
Where are the Transitional Fossils?
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.
Series: Made in the Image of God: The Theological Implications of Human Genomics (4 entries)
This series by Denis Alexander reflects on advancements in genomics as well as their theological implications. He focuses on the relatedness of hominin genomes, arguing that this does not interfere with the image of God in humans. The image of God depends more on the capacity for relationship and covenant, not on a list of particular physical qualities. He then discusses why the recent studies of genomics provide “no grounds for genetic determinism.”
Series: Biblical and Scientific Shortcomings of Flood Geology (6 entries)
Gregg Davidson and Ken Wolgemuth seek to remove the stumbling block of the Genesis flood in this four part series. Though many believe in an ancient world-wide flood, the evidence given does not hold up to geological scrutiny, but points rather to something regional instead. It is their hope that Christians will not walk away from faith in Christ simply because a global flood is not supported by science. Looking at natural phenomena like the Grand Canyon, salt beds, and fossil deposits, they reveal reasons for these deposits and structures while showing that their origin did not stem from a violent flood that covered the planet.
David Lack and Darwin’s Finches
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.
What scientific evidence do we have about the first humans?
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.
Possibilities and Second Chances
In today’s video, Dr. Rick Colling states that evolution is not merely the imposition of death and destruction and survival of the fittest. Rather, it is about second chances.
Series: Understanding Evolution (4 entries)
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.
Series: New Limbs from Old Fins (7 entries)
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.
Series: The Cambrian "Explosion", Transitional Forms, and the Tree of Life (8 entries)
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.
Series: The Flood: Not Global, Barely Local, Mostly Theological (4 entries)
The three part series, written by Paul Seely, explores the scientific validity of the Flood in Genesis. He offers the approximate date of the flood according to Scripture, and then looks at various lines of evidence that contradict the idea of a global flood at that time. In light of other Mesopotamian flood stories, scholars conclude that the flood was local at best. In the end, he suggests that this story primarily reveals theological truths from a limited scientific understanding of natural events.
Adventist Origins of Young Earth Creationism
Many evangelicals believe that Young Earth Creationism is the only authentic, biblical way for Christians to understand origins, and that until the advent of Darwin's theory of evolution, it was the only view held by Christians. However, in this excerpt from Saving Darwin, Karl Giberson explains that Young Earth Creationism's origins are surprisingly recent.
