Matt: However my reasons for believing a new species won&apos;t just arise &quot;de novo&quot; are manifold:[/color]&#13;&#10;> &#13;&#10;> 1. It has never been observed. <--That&apos;s a big one.-How do you explain all the new findings from the Cambrian explosion? It all seems very de novo to me.&#13;&#10; &#13;&#10;> &#13;&#10;> Matt:Really, then what about the symbiotic thesis that stands for how we grabbed mitochondria? And the way our intestines work with our flora, it pretty much means precisely that one strategy for survival is many, different communities of organisms working together in tandem. E.O. Wilson has argued extensively that Eusocial behavior exposes organisms to a whole new plateau of evolutionary development that wasn&apos;t possible before. -Perfectly reasonable for me. &#13;&#10;> > &#13;&#10;> > David:You are quoting pure speculation. &#13;&#10;> &#13;&#10;> Matt:No, I&apos;m quoting theory that&apos;s used in actual research:&#13;&#10;> &#13;&#10;> http://www.nrcresearchpress.com/doi/abs/10.1139/g84-038&#13;&#10;> &#13;&#10;> This particular paper recreated in the lab precisely what was observed in nature, demonstrating that not only is that definition of speciation valid, its testable. Something lacking in any alternative you&apos;ve presented.-The abstract I found looked at mosquito hybridization. Must be an incorrect reference. Makes no sense in your line of reasoning. &#13;&#10;> &#13;&#10;> > > &#13;&#10;> > > Matt; Could you do better to explain what you mean by discrete jumps, &#13;&#10;> > &#13;&#10;> > David: I can parphrase Gould. The palentologist&apos;s guarded secret is that all we have got is the tips and nodes of branches of the trees.&#13;&#10;> &#13;&#10;> Matt: Except in certain clear-cut cases, such as the progression of horse fossils.-You could mention the whale series also, but note both fit Gould. Where are the intermediate forms? In both cases we are seeing giant leaps of morphology. I&apos;m still with Gould and Eldredge on punctuated equil.
