About the BioLogos Forum

The BioLogos Forum is designed to foster a serious and comprehensive discussion of Christian faith and the sciences. We believe that charitable engagement of different perspectives within the Church helps sharpen our thinking and deepen our commitment to the truth that is hidden in Christ. So while many of the articles and videos under the distinctive Forum banner come from BioLogos staff and Senior Fellows, we feature a range of voices, including those that disagree with us and with each other. Unless otherwise noted, views expressed are those of the authors, not necessarily of The BioLogos Foundation. You can read more about what we believe here, and join the conversation in the comments section at the end of each post.
Understanding Evolution: Is There “Junk” in Your Genome?
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.

Understanding Evolution: Is There “Junk” in Your Genome? Part 1
There are various ways to test the hypothesis that certain regions of DNA are non-functional, and in this series we will explore some of them.
Is There “Junk” in Your Genome? Part 2
Despite their somewhat mysterious nature, transposon sequences make up a staggering 45% or more of our genome. They are the perfect parasites: using their host to provide resources, they maintain a “lifestyle” so simple that replication is essentially their only feature.
Is There “Junk” in Your Genome? Part 3
In this post we’ll discuss the mechanism by which processed pseudogenes (literally "false genes") arise, and then discuss how a small fraction of them pick up functions and become “real” themselves.
Is There “Junk” in Your Genome? Part 4
Now that we have covered significant ground with respect to what various classes of pseudogenes are and how they arise, we are now able to properly evaluate antievolutionary arguments put forward in an attempt to discredit these lines of evidence for evolution.
