<p>I understand that you think the designation of species, sub-species, race etc is artificial. But what about the higher levels on the classification system, such as genus? Or even higher ones such as domain or kingdom? The designations may be crude, but they have helped our understanding of how organisms evolve and are related to each other. </p>
<p>As for my condemnation of polygenism - yes, there are two aspects to it: the scientific aspect and the ethical aspect. In <em>all</em> of my posts I have mentioned the scientific aspect first. But I don’t deny that I believe a theory which uses crackpot science to defend human rights abuses is ridiculous. </p>
<p>As for alternative theories - the problem is, you haven’t given a viable one. I’ve already commented on the possibility that modern man originally developed in South Asia. That has nothing to do with being PC. It has to do with the fact that science does not support it. </p>
<p>As for further speciation - could you explain your ideas on this a little more? I would be interested in your thoughts. :)</p>
