An Alternative to Evolution: Expounded Upon (Introduction)

DAVID: There are two ways to use the term common descent as I see it: first is the Darwin view of descent with a natural graduated modification from one form to another. The second is punctuated equilibrium in which there is modification, but the gaps in the modification are so large it is never by graduated modification, but implies a designed modification which is not a result of natural forces. My view is the latter is the correct theory and is what I imply when I use the term common descent. I do not accept Darwin's view of common descent.

dhw: This is a quibble. You accept common descent (i.e. that all life forms except the very first descended from earlier life forms), but you reject gradualism and accept punctuated equilibrium, and you believe in design not chance.

Not a quibble, as there are two ways to define common descent, an entirely natural one which I reject and process designed and managed by an agency, God. I was really debating with Tony his dispensing with the common descent idea completely. I think I can define it in a way he might accept.

Tony: Common Decent of all life from a single organism does not fit the evidence, violates all sorts of laws across a broad spectrum of scientific disciplines from physics to information theory, and is dependent upon a function (speciation) that has never been observed.

dhw: The origin of life remains an unsolved mystery, but I think we would all agree that living organisms exist. Please tell us what scientific evidence you have that organisms can spring into existence from nowhere without a predecessor, and name one observer of this phenomenon.

You are trying my approach to the common descent definition.
