Series: Decoding ENCODE
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".

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
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.
Signature in the Pseudogenes, Part 1
One interesting feature of looking at genomes is that often we can find the mutated remains of once-functional genes. These are called pseudogenes, or “false genes.” Pseudogenes might be part of a shared backstory for two species, or they might crop up independently after two species go their separate ways.
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.
Denisovans, Humans and the Chromosome 2 Fusion
The Denisovans, an extinct hominid group that interbred with modern humans, made the news again lately with the publication of a more detailed study of their genome. One of the many interesting findings was that the Denisovans share the same chromosome 2 fusion that modern humans have.
Genesis and the Genome
This article provides an overview of genomics evidence for common ancestry and hominid population sizes, and briefly discusses the implications of these lines of evidence for scientific concordist approaches to the Genesis narratives.
Series: Understanding Evolution: the Evolutionary Origins of Irreducible Complexity
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 examine evidence that proteins in irreducibly complex (IC) systems can form and refine new interactions through gradual mechanisms.
Theory, Prediction and Converging Lines of Evidence, Part 2
We have already discussed hind limb and hair loss in whales, and now we turn to one of the remaining questions: tooth loss in the lineage leading to modern toothless whales.
What is the genetic evidence for evolution?
Darwin developed his theory of evolution by looking at scientific evidence available in the mid-1800s. Since then, the whole field of genetics has developed, adding a powerful independent line of evidence in support of evolution. Genes show how the physical traits of living things are handed down and modified from one generation to the next. By comparing the DNA of many organisms, scientists can map the relationships between species. This map is in remarkable agreement with Darwin’s predictions. The structure of chromosomes and particular genetic sequences point to the conclusion not just of common design, but common descent as well.
Series: Behe’s B Cell Bravado
This three part series by Kathryn Applegate argues strongly against Michael Behe’s claim that the immune system is irreducibly complex. She begins with a brief review of antibody generation in B-cells. Then, she addresses Behe’s invalid assumptions about this process. Looking at the function of bacterial transposons, she then provides a reasonable explanation for the gradual evolution of the system and calls Behe to engage the scientific literature.
Series: Behe, Lenski and the “Edge” of Evolution
In this series, we reexamine the claim made by Intelligent Design proponent Michael Behe to have found a limit to “Darwinian” evolution in light of recent results from the laboratory of Richard Lenski.

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
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: Asa Gray and Charles Darwin Discuss Evolution and Design
Many Christians believe that they face a painful choice-- either life was designed by God or it is an evolutionary product of natural selection. Charles Darwin himself believed in this dichotomy, and people ever since have felt the need to "choose sides". However, looking back at history, we find that one of Darwin's chief scientific colleagues, Asa Gray, did not share this perspective. In this three-part essay, part 1 charts the relationship of Asa Gray and Charles Darwin. Part 2 describes Darwin's struggle with the problem of natural evil and design in nature, and part 3 explores how Asa Gray was able to embrace evolution without rejecting the idea of design.
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.
Series: The Human Fossil Record
In this series, James Kidder provides an intriguing study on transitional fossils and the evolutionary history of modern humans. He begins by discussing the fossil record, explaining how new forms are classified. He then explains the physically distinguishing trait of humankind—bipedalism. From the discovery of Ardipithecus, the earliest known hominin, to the australopithecines, the most prolific hominin, Kidder focuses on the discovery, the anatomy, and the interpretation of these ancestral remains.
Gracious Dialogue
Our desire to engage in gracious dialogue with fellow believers who reject biological evolution has been receiving increased attention in both the Christian and secular press. More importantly, we are being joined in this reconciling project by our brothers and sisters in Christ who have often been defined primarily as our “opponents”.
