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.

Blog series: Understanding Evolution: the Evolutionary Origins of Irreducible Complexity

By Dennis Venema
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 examine evidence that proteins in irreducibly complex (IC) systems can form and refine new interactions through gradual mechanisms.

Blog article: Where is the Genetic Evidence for Evolution?

By Kelsey Luoma
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.
