Written by BioLogos Fellow of Biology Dennis Venema, this series of posts is intended as a basic introduction to the science of evolution for non-specialists.

Astronomers have many different methods for measuring the age of various objects in the universe, and they all support ages of billions of years, not thousands. Even if the assumptions of one or two methods were faulty, it is highly unlikely that all of the methods would be affected.

No one need ask: “Were you there?” Chuck Steidel has tapped into nature’s own motion picture of past events, now showing in the present. Anyone who cares to view it can now see for himself what was and wasn’t there, at various stages of the deep past.

The Galápagos Islands were not a distinct “center of creation,” but a workshop for evolution in which an ancestral species made it to the yet uncolonized island and underwent a massive degree of speciation to adapt to the environment of the island. This is precisely what one would expect if the species of islands had arisen by evolution.

In our current culture, we’re defined by our jobs. It’s having a vocation. I wanted to shift away from that. I didn’t want to be a doctor first and foremost, or a scientist, but one who praises God.

Right on this tabletop, you could make materials that by current manufacturing processes would otherwise cause a great amount of environmental hazard … In 50 years, we should be able to do things in ways we don’t do them now, that will be cheaper, less toxic, less polluting, more efficient, and so forth…

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.

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.”

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.

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 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.

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.

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.

We live in exciting times for a geneticist: more and more genomes are being sequenced, and more and more novel genome-wide analyses are being performed to shed light on what all those newly-determined sequences mean.

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.
