A new theory suggests that the molecular clock, which estimates the timing of evolutionary events, may have sped up during major evolutionary transitions, potentially explaining the 30-million-year gap between the predicted age of the common ancestor of complex animals and their first fossil appearance, thus aligning Darwin's theory with fossil evidence.
A recent study explores the genetic and molecular basis of the evolution of upright walking in humans, highlighting its significance as a key trait that distinguishes humans from other primates, building on Darwin's theories of human evolution.
New research analyzing earthworm genomes suggests that evolution may occur through rapid, significant changes rather than slow, incremental ones, challenging traditional Darwinian theory and indicating that our understanding of evolutionary processes might need to be revised.
NPR's correspondent shares her fascination with the blue-footed booby during a trip to the Galápagos Islands, highlighting their unique appearance, behavior, and historical significance in Darwin's theory of evolution.
In the early 1800s, the debate over whether animals could evolve into new species was fueled by the discovery of mummified animals from Egypt. Naturalists Georges Cuvier and Jean-Baptiste Lamarck represented opposing views, with Cuvier mocking Lamarck's theory of transformism in an obituary. The mummified animals, including ibises, cats, and crocodiles, were examined for evidence of species change, but their similarity to modern counterparts seemed to support Cuvier's belief in the unchanging nature of species. However, this debate was reignited with the publication of Charles Darwin's On the Origin of Species in 1859, acknowledging Lamarck as a predecessor in the study of species modification.
