For Darwin, both of these observations (that oceanic islands lacked terrestrial mammals, and that endemic species on islands were most similar to a species on the closest mainland) had the same explanation: his hypothesis that endemic, oceanic species were the modified descendants of a colonizing species from the nearest continent.

... I would exhort these, my fellow conservative evangelical shepherds and thinkers, to set aside all reticence and fear, emerge from anonymity, and storm the forum of discourse, engaging this most pressing matter with vigor, equanimity, and humility. In doing so, know upfront that there will be few handrails to guide; you will not be building upon an extensive precedence of published conservative thought.

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.

Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood. Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet.

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 our sixth BioLogos videocast, we take a look at the age of the Earth. We explain four methods scientists have used to determine that age: tree ring, lake varve, radiometric, and seafloor spread dating, and also offer some theological insight on how an old earth can fit with the first chapters of Genesis.

The debate is often not about evidence, but about making sure that others do not transgress our interpretive boundaries and insist that we're wrong. We've bitten from the tree of knowledge and we love its taste.

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".

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.

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 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.

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”.

In this series, Davis identifies core tenets or assumptions about the view of concordism, beginning with propositions about the Bible before concluding with a short historical commentary.

The BioLogos Forum is pleased to present this infographic about the tools scientists use to determine the age of the Earth. The graphic, titled "How Do We Know the Earth is Old?", uses data compiled and summarized by geology professor Dr. Gregg Davidson.

We've recently been looking at the evidence for an old earth and the long history and vibrancy of this view among evangelical Christians. Today’s post features a preview of the updated Question, “How are the ages of the Earth and universe calculated?" revised by Senior Web Consultant and Writer Deborah Haarsma.

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.

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.

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.
