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.
Katharine Hayhoe: Evangelical Christian, Climate Scientist
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.
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.
Series: New Limbs from Old Fins
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.
Series: From ID to BioLogos
In this series, Dennis Venema describes his personal journey that took him away from the Intelligent Design arguments toward the evolutionary creation worldview. Through careful and honest research, he discovered ID scientific reasoning to be analogy-based, in sharp contrast to evolutionary science, which was supported by concrete data. After accepting this view, God’s presence ever strengthened him as he explored the compatibility between the Bible and God’s creative mechanism.
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.
Stewards of God’s (Changing?) World
Interestingly, I find this sort of cynicism about climate change especially prevalent among Christians. Why is this?
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...
In The Bones
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.
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.
For the Love of the World: John Stott and His Passion for Creation
Some criticized John for his theistic evolutionary position and even his appreciation for Darwin. But Stott saw no contradiction between his own commitment to the authority of Scripture and his openness to God’s use of evolution in His creative process.
Misconceptions About Evolution, Part 2
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.
Misconceptions About Evolution, Part 1
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.
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: Evolution and the Origin of Biological Information
Dennis Venema begins this series by summarizing a key Intelligent Design belief: that if we see specified information, we infer design because we are unaware of a mechanism that can bring about specified information in the absence of intelligence. In each subsequent part of the series, Venema shows why this argument is wrong. Venema presents evidence to show that natural mechanisms can, in fact, explain the origin of new information. He reminds his readers, however, that this does not in any manner exclude God from the process.
Thanksgiving, Mediterranean Style
As much as I love the fertilized soccer green at the foot of the library, I can’t imagine Gordon College without the woods and wetlands. They are our best classrooms.
Songs and Speciation
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.
What evidence do we have for evolution besides fossils and genes?
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.
