"....general theory of evolution....as defined by Gerald kerkut as .....the theory that all the living forms in the world have arisen from a single source, which itself came from an inorganic form.....          I think there is also that which is called the specific theory of evolution, which deals with what is observable changes in organisms."

I 'googled' Gerald Kerkut and it appears that he was a British scientist who published a book called 'The Implications of Evolution'. In this book he pointed out the gaps in our knowledge of evolution and these gaps have been eagerly seized upon by creationists as support for their case that evolution is impossible and that ... errr ... God did it!

And when did Kerkut publish his book? In 1960 that's when! 55 years ago! 55 years is an awful long time in terms of advances in scientific knowledge.

So, Pete, what's the current status of Kerkut's work among evolutionary biologists (not creationists)? I'll let you do the work.
