Episode Details

We’ve all admired the long, majestic neck of the giraffe, and the question remains: how did the giraffe get its long neck? Is it a product of an evolutionary process? Or was a process of foresight and purpose involved? Helping us unpack this today is retired geneticist Dr. Wolf-Ekkehard Lönnig, who challenges the traditional narrative of giraffe evolution, noting a sharp disconnect between Darwinian predictions and the actual fossil record. While neo-Darwinism, by default, expects a gradual, step-by-step progression of slight variations leading to the modern giraffe, the geological evidence tells a different story. Learn how the twin problems of stasis in the fossil record and silos in the development of giraffes pose major problems for the standard just-so story of giraffes.
