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.
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".
Series: Asa Gray and Charles Darwin Discuss Evolution and Design
Many Christians believe that they face a painful choice-- either life was designed by God or it is an evolutionary product of natural selection. Charles Darwin himself believed in this dichotomy, and people ever since have felt the need to "choose sides". However, looking back at history, we find that one of Darwin's chief scientific colleagues, Asa Gray, did not share this perspective. In this three-part essay, part 1 charts the relationship of Asa Gray and Charles Darwin. Part 2 describes Darwin's struggle with the problem of natural evil and design in nature, and part 3 explores how Asa Gray was able to embrace evolution without rejecting the idea of design.
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.
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...
Ard Louis on Intelligent Design
In this short video, physicist Ard Louis expresses some doubts about Intelligent Design, noting that his primary resistance to the movement is based on theological grounds rather than science.
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.
Beginning with the End in Mind
In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris over the idea of evolutionary convergence.
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.
The topic of Intelligent Design (ID) comes up frequently here. Because ID can be hard to pin down, it’s worth pausing to remind ourselves what we’re talking about when we use the term on this site.
What Do You Mean When You Say "Evolution"?
In this video clip, Oxford University biophysicist, Ard Louis posits that one of the reasons Christians are hostile to evolution is that they latch onto a particular definition, which puts it in conflict with their theological convictions.
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.
