On neo-Lamarckian Evolutionary Theory

It cannot be denied that after travelling the world and observing many non-human life forms carefully, Charles Darwin made a great contribution to science. But like Adam Smith before Professor John Nash, his theory was quite incomplete; and even inaccurate in important particulars; incidentally giving license to right wing war mongers and such; Like the Nazi regime for one example. The whole supposition that genetics are selected for and change with each generation is a fallacy not without a good kernel of truth; but still a fallacy. After all in species that evolved over millions of years, drastic genetic change in every generation would interfere with genetic information accrued and tested over said millions of  years. We made a great mistake in ignoring the evolutionary theory of the Frenchman Jean Baptiste Lamarck who accurately observed that the genetics of an animal like a giraffe could change in a single life-time; contradicting Darwin's theory; and giving us a theory of life and not death. But we must go far beyond Lamarck; We must make serious study of Carl Sagan's evolutionary theories; but not take them as gospel either. The world of genetics and reproduction and the evolution of species is far more complex and interconnected than early models imagined. We should even question what constitutes a lifeform as evolution concerns not primarily individuals but populations. Genetic information circulates through these populations even without direct reproduction in ways we simply don't understand yet. But we must make a serious study of these matters.
