i 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: An Introduction to Populations and Speciation

Understanding Evolution

This blog series by Dennis Venema undertakes the task of clarifying numerous aspects of evolution that often become misconstrued by Christians. He first discusses the idea of speciation in a population over time, later applying it to the speciation process that occurred among hominids (human ancestors) which led to modern humans. He continues to support this idea by exploring so called “Mitochondrial Eve,”“Y Chromosome Adam” and other compositional clues of the human genome.

Understanding Evolution: An Introduction to Populations and Speciation

One misconception of evolution among Christians (and even for students of biology) is that the production of new species is a sudden event, or one that begins through a single breeding pair. In reality, new species arise through incremental changes to populations, not individuals.

Neanderthals, Denisovans and Human Speciation

It is now possible to obtain and sequence DNA from Neanderthal remains, and the complete genome sequence of Neanderthals was published in early 2010. The results were fascinating...

Speciation and Incomplete Lineage Sorting

Speciation and Incomplete Lineage Sorting

One consequence of speciation being a population event is that populations have genetic diversity – not all members of the population are genetically identical. For any particular gene, then, a population may have several slightly different forms present within it. These different forms are called alleles.

Mitochondrial Eve, Y-Chromosome Adam, and Reasons to Believe

Mitochondrial Eve, Y-Chromosome Adam, and Reasons to Believe

When presented with the evidence for human population sizes over our evolutionary history, a common point of confusion for evangelicals is how this evidence fits with Mitochondrial Eve. How can we all come from one woman (and one man) but also come from a large population of 10,000 individuals?
