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 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...

“I flatter myself,” Hume triumphantly proclaimed, “that I have discovered an argument . . . which, if just, will, with the wise and learned, be an everlasting check to all kinds of superstitious delusion, and consequently, will be useful as long as the world endures.”

Does God need to supernaturally "intervene" in order to bring about the diversity of life that we observe today? Is that kind of action different from God’s ordinary action? We begin our three-part series with Robert John Russell’s description of how views of divine action have changed throughout history, excerpted from his book Cosmology: From Alpha to Omega. Part 2 addresses why “intervention” in the natural world is a problem philosophically, theologically, and scientifically; and Part 3 explains Russell’s own theory of divine action in the natural world.

We think that God created all living organisms, including humans, through the evolutionary process. But acceptance of creation through evolution does not mean that we reject the notion of a miracle-working God. On the contrary...

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.

I find that when many Christians think about the way God created our universe, they often bring a static expectation similar to what we bring to an ordinary statue. It’s as if we assume the physical realm were merely a rigid three-dimensional sculpture, immovable with time.

“That just doesn’t sound right.” Ever since I was a kid, that was my gut reaction to those well-meaning people in my church and school who told me that despite what many in the sciences were saying, the earth and the entire universe were actually of relatively recent manufacture.

In this three part series, geologist Stephen Moshier critiques John MacArthur’s articles on uniformitarianism, while offering an alternative perspective on the principle. He exposes faulty conceptions about and misleading definitions of uniformitarianism. Gregory Bennett further defends the idea of an old earth as Biblical and focuses on the unchanging nature of God. He also discusses the Scriptural doctrines of creation and God’s providence.

In this video conversation, Jeff Schloss makes the observation that when we use the term “evolution”, it is not always exactly clear what we are actually discussing unless we denote the intended usage.

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.

Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in glaciers that can be counted back 740,000 years. Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years. Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years. The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old. (Updated April 16, 2012)

God acts in more than one way in the natural world. God sustains the regular patterns of the physical world, but sometimes chooses to act outside of those patterns. God’s regular patterns are what scientists describe as natural laws (like gravity or photosynthesis). God’s actions outside those patterns are usually called supernatural actions or miracles (like raising someone from the dead). Evolutionary creationists believe in the miracles of the Bible and that God can do miracles today. Evolutionary creationists also believe that God is just as involved in the regular patterns of the universe as in miracles. (Updated on March 10, 2012)

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.

In this video, Brian McLaren discusses the idea of surrogate arguments, in which a debate over one thing is really a means for arguing something completely different. According to McClaren, the argument over the age of the earth is one such argument.

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.

Evolution is the biological model for the history of life on Earth. While some consider evolution to be equivalent to atheism, BioLogos sees evolution as a description of how God created all life. Evolution refers to descent with modification. Small modifications occur at the genetic level (in DNA) with each generation, and these genetic changes can affect how the creature interacts with its environment. Over time, accumulation of these genetic changes can alter the characteristics of the whole population, and a new species appears. Major changes in life forms take place by the same mechanism but over even longer periods of time. All life today can be traced back to a common ancestor some 3.85 billion years ago.

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.

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.
