The Simple Life: Abiogenesis Gets Another Reality Check

When it comes to biological life, even the simplest single-celled organism is an astonishingly complex multi-part system. Just how simple can a living cell get? On this ID The Future, Eric Anderson hosts another conversation with Dr. Robert Sadler to evaluate the claims of abiogenesis researchers. A recent Nature paper reports on an engineered minimal cell and how it contends with the "forces of evolution" compared to the non-minimal cell from which it was derived. In an attempt to find life's lowest common denominator, experimenters reduced the minimal cell down from 901 genes to 473 genes. The result was a fragile, irregular organism, sheltered and well cared for. But does this reduction in genomic complexity demonstrate evolution or devolution? Is it an unguided process at work or adaptation within the boundaries of an organism's design? "When people speak of evolution, they speak of random changes and natural selection," Sadler says. "But are they really random? Or does the organism have a built-in ability to change the genome to its own benefit?" Sadler puts the paper's results and claims in perspective for us. Read More ›

The Origin of Life was the Origin of an Engineering Marvel

On today’s ID the Future, physicist Brian Miller touches on various challenges facing the origin of the first life. He and host Eric Anderson discuss Jeremy England’s origin-of-life ideas and the RNA World Hypothesis, and offer multiple reasons why they are convinced that various proposed mindless processes do not explain the origin of the first self-reproducing cell. Miller urges another approach, one that draws on engineering principles and embraces the evidence in even the simplest cell of highly intelligent engineering.

Origin of Life’s Purple Unicorn: Protocells

On today’s ID the Future, host Eric Anderson sits down with Rob Stadler, co-author with Change Tan of The Stairway To Life: An Origin-Of-Life Reality Check. The topic of discussion–protocells. Stadler notes that the simplest existing single-celled organisms are far too sophisticated to have emerged through a blind process of prebiotic evolution. He further notes that this is widely acknowledged in the origin-of-life community, but those committed to a purely materialistic origin of the first life have a fallback explanation–protocells. That is, early biological structures far simpler than anything we find today. An intriguing hypothesis, but the problems with it, according to Stadler, are legion. Tune in as Stadler and Anderson walk through several lines of evidence that appear to break against the much sought-after but ever-elusive protocell.
