a robust scientific theory... defined as a theory which gains support through evidence garnered from a number of different disciplines.

When Darwin wrote his book on the origins of species, he knew very well that he lacked a mechanism whereby traits were passed from one generation to the next. With the development of the study of genetics, that lack was replaced with new information... evidence, if you will, supporting Darwin's hypothesis.

A century later, exploration of the sea bottom turned up more information that lead to the study of plate tectonics... that not only explained continental drift (a much abused theory for many years) but also provided more evidence of long term changes to the earth which also supports Darwin's theory.

There is not a single field of science that negates the theory of evolution... after a century and a half of people seeking to do just that. It's only half baked pseudo scientific claims that do not hold up to independent study that pete can reference. Faith is not science... an scientifically trained people who feel compelled to ignore facts thta conflict with their faith held beliefs are being dishonest to themselves and the rest of the world. A pity they feel a need to shackle their all powerful diety to ancient fairy tales.
