Seeking Understanding: John Walton
If you have ever heard of “free radicals,” you know something about the work of Dr. John Walton, a professor of chemistry at St. Andrews University in Scotland. Dr. Walton’s work concentrates not only on the destructive reactions that come to mind when most people think of free radicals, but also on the positive effects of these fascinating chemicals. He also studies the potential of free radicals in industrial and environmental chemistry. What we know about free radicals because of the work of Dr. Walton and other chemists can also inform our understanding of how life came into being. Based on his life as a scientist and the research he has done, what does Dr. Walton believe to be the most reasonable explanation of life’s origin? This is the subject of this 22:30 episode of the Seeking Understanding series.
Design in Other Animals
Are other creatures fundamentally different from humans? The surprising answer is both “Yes” and “No”. Why does the biblical account of creation lead us to believe that there should be profound similarities between humans and other living things? What makes us different? How does the Bible define the relationship between humans and other creatures? Shelley Quinn and Tim Standish, PhD

Noemí Durán - In the Beginning, There Was Love
“Survival of the fittest" and “struggle for existence." You have probably heard these expressions before, likely in connection with one of the most famous concepts in evolution: natural selection. Competition and violence are presented as the necessary tool that allowed for the emergence of biodiversity, in contrast with the biblical account of a “very good" creation. In this talk, Dr. Durán illustrates fascinating examples of altruism and cooperation in the animal world, challenging the dominant narrative and pointing back to the time when animals were designed to show the loving character of God.
The Theory of Evolution
Charles Darwin's theory of evolution was based on natural selection as the engine of change in living beings. Later, with the advances in genetics, mutation was added to the theory as the source of the variations on which natural selection would act. The mutation-natural selection binomial thus became the main mechanism proposed for biological diversity. Do mutation and natural selection have the creative capacity assigned to them? Can they transform an organism into a different one by means of small changes accumulated over a long period of time? Are there other natural mechanisms that can do the job?
