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".

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.

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.

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.

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.

Evolutionary theory is not in crisis; scientists accept evolution as the best explanation for life's diversity because of the multiple lines of evidence supporting it, its broad power to explain biological phenomena, and its ability to make accurate predictions in a wide variety of situations.

The website Understanding Evolution, hosted by The University of California Museum of Paleontology, Berkeley, offers its readers numerous helpful resources regarding the science and history of evolutionary biology.

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.

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.

Scientists have found multiple lines of evidence for evolution, not just one or two. These types of evidence are independent of each other, coming from sources as different as ancient fossils and modern genetics labs. Evidence also comes from comparing the anatomy of creatures living today. All creatures with four limbs (whether mammals, birds, or reptiles) have the same bone structure in each limb, pointing to their descent from a common ancestor. More evidence comes from biogeography. Isolated islands are missing common species found on the mainland, but are filled with many unique species that can be related by a common ancestor. Finally, evidence comes from embryonic development. As an embryo of a mammal grows, its heart develops through stages similar to fish, amphibians, and reptiles. God’s creation declares the history of life in many different ways. All these ways are pointing to a consistent picture of God creating through evolution.

There are two opposite errors which need to be countered about the fossil record: 1) that it is so incomplete as to be of no value in interpreting patterns and trends in the history of life, and 2) that it is so good that we should expect a relatively complete record of the details of evolutionary transitions within all or most lineages.

Last week I came across a blog post by Intelligent Design leader Bill Dembski, provocatively titled "Craig Venter denies common descent — Dawkins incredulous." Surprised by the headline, I clicked over to read the story.

Kenneth Miller tells a story of catching two students plagiarizing. It seemed quite clear that the two students had submitted the same papers, but the two argued it was merely by chance and that the fact that they were roommates explained why the papers seemed similar.

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.

Andy Crouch examines the life of a scientist based on his experience of walking alongside his wife Catherine, an experimental physicist. That relationship has shown him that a life in science is a journey “into a set of virtues,” of cultivating a specific character suited to the particular demands of research and investigation. Crouch's hope is to persuade pastors and others in the church to prayerfully support the scientific endeavor as a reflection of God’s image in humankind as well as offers some suggestions for ministering to their needs.

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.

If we can understand the experiences of the people who work every day in the lab, our dialogues concerning science and religion will be far more fruitful.

As an Evangelical and a scientist, Katharine Hayhoe is already a member of a rare breed. As a climate change researcher who is also married to an evangelical Christian pastor, she is nearly one of a kind.

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...
