A Vivid Demonstration of Bacteria Adapting to Antibiotics via Mutations and Selection

The fact that bacteria are able to develop resistance to antibiotics has been a textbook example of evolutionary processes in action.  Mutations and natural selection—two primary agents of change—work together to sculpt new genetic combinations allowing individuals to exploit resources unavailable to bacteria previously unable to resist antibiotic chemicals in their environment.   Now you can watch a powerful...

A 60,000 Year Varve Record from Japan Refutes the Young-Earth Interpretation of Earth’s History

Do places on Earth exist where annual records have been stored for tens of thousands of years and can be accessed today? Ice-cores and tree rings can preserve long records of yearly events but some of the best records come from layers of sediment underlying some lakes which,  if formed under the right conditions, can be read like the annual rings of...

Reflections on the Death of Toads and the Edenic Perfect Paradise
