Shortly before midnight on Sunday 14th April 1912, RMS Titanic struck an iceberg in the North Atlantic and sank at 2.17 am. What made this tragedy particularly shocking at the time was that Titanic was widely believed to be unsinkable - by passengers, crew and by the public at large. Today Darwin's theory of evolution enjoys a similar 'unsinkable' reputation. The thesis of this book is that 19th century Darwinian science, developing as it did in an age that also gave rise to supreme confidence in Titanic's unsinkability, has collided with the 'iceberg' of 21st century molecular biology. We conduct an inquiry into the evidence and its worldview implications. What if - just as Titanic had design flaws that rendered it unsinkable only in a limited sense - what if the science underpinning the Theory of Evolution turns out to be valid only in a strictly limited sense? The amazing discoveries in the late 20th and especially in the early 21st century - of the exquisite micro-molecular
