Series: Decoding ENCODE (8 entries)
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: David Lack and Darwin's Finches (4 entries)
Not only are evolution and biblical faith compatible, but committed Christians have been at the forefront of evolutionary science ever since Darwin published On the Origin of Species in 1859. This series looks at David Lack, an ornithologist and devout Christian who contributed greatly to the understanding of Darwin's finches.
Series: Understanding Evolution: Is There “Junk” in Your Genome? (5 entries)
One of the challenges for discussing evolution within evangelical Christian circles is that there is widespread confusion about how evolution actually works. In this installment on “junk DNA”, we explore how genomics can be employed to test for non-functional sequences by comparing sequences between related organisms.
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 (7 entries)
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: Signature in the Pseudogenes (3 entries)
This brief series explains the significance of pseudogenes. Darrel Falk and Dennis Venema demonstrate how the theory of common descent provides a fine framework in which to interpret the existence of these once-functional genes. They also discuss the relationship of various primates and other mammals based on shared pseudogenes. The evidence in support of evolutionary theory, they argue, is compelling when examining the rich history disclosed in the DNA of every organism.
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...
Evidence for Evolution in the Mouths of Birds
A friend tells me the most important task for The BioLogos Forum is to present evidence of evolution in ways people without a biology background can understand.
Series: Evolution Basics (50 entries)
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.
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.
Series: Evolution and the Origin of Biological Information (7 entries)
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.
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: Understanding Evolution: Theory, Prediction and Converging Lines of Evidence (4 entries)
One of the challenges for discussing evolution within evangelical Christian circles is that there is widespread confusion about how evolution actually works. In this installment we explore how evolution is a theory in the scientific sense, how it is supported by converging lines of evidence, and how it can make accurate predictions about the natural world, using whale evolution as an example.
What is the genetic evidence for evolution?
Darwin developed his theory of evolution by looking at scientific evidence available in the mid-1800s. Since then, the whole field of genetics has developed, adding a powerful independent line of evidence in support of evolution. Genes show how the physical traits of living things are handed down and modified from one generation to the next. By comparing the DNA of many organisms, scientists can map the relationships between species. This map is in remarkable agreement with Darwin’s predictions. The structure of chromosomes and particular genetic sequences point to the conclusion not just of common design, but common descent as well.
Series: A Tale of Three Creationists (3 entries)
In this three part series, Dennis Venema introduces and highlights Todd Wodd—a biologist who validates evolution as a credible theory, yet rejects the theory itself on a Biblical basis. In other words, Wood is a Young Earth Creationist. Despite their different perspectives, however, both he and Venema offer similar scientific critiques of arguments made by Reasons To Believe (RTB) including their view that physical, anatomical and genetic similarities as well as shared pseudogenes do not imply common ancestry between two organisms. The careful evaluations made by both Venema and Wood demonstrate the scientific weaknesses in RTB’s theories.
Series: Saturday Science Links (22 entries)
The biggest science stories of the week are reviewed.
The Changing Face of Evolutionary Theory?
Is evolution driven mainly by random genetic variation, or are there other factors at play? Michael Burdett reviews the scientific debate.
Series: Reviewing “Darwin’s Doubt” (11 entries)
I was raised in a household of atheists. My parents were card-carrying members of the American Communist Party, and therefore the atheism in my household was quite close to the militant anti-theism of the so-called “new atheists”.
