umm, what? Darwin's finches comes to mind [1]. Also, since then, a host of other examples. All you need to do is look at the Wikipedia page [2], which has citations to the primary research. Unless you mean, no one has seen it happen inside a lab? But that's not true either.., accelerated evolution experiments with uni-cellular species with different "sexes", leading to reproductive isolation (ergo, speciation) has been shown [3]. How about multi-cellular species where this has been demonstrated at the broad genetic & physiological / behavioral level? That's been done too. See these two for a review of some of the work [4,5].

None of your citations, including Darwin's finches, prove evolution. Your citation #3 states "In conclusion, we have succeeded in creating an artificial reproductive group that is isolated from the WT group." They artificially castrated a species; that is not evolution. Citation #4: "The authors suggest that reproductive isolation has evolved in situ as a result of...". Again, not proof. Citation #5 adds no value at all: "Although the sample of genes characterized thus far by various laboratories remains small, and concentrated in the genus Drosophila, I suspect that these patterns may prove general, although likely not universal. Our recent work, along with that of several other groups, also suggests that the selection underlying the evolution of speciation genes may sometimes assume a surprising form, response to intragenomic conflicts, perhaps involving meiotic drive." Keywords: suspect, suggests, may, perhaps You may want to believe evolution so badly, but science doesn't have the proof yet, and that is a fact.

    Please don't take HN threads further into religious flamewar. Of all directions not to go, that may be the nottest.

      I’ll just not comment on this anymore, but I’m afraid I was responding to an existing religious flame war, not creating it. I’ll be careful not to fuel such fires again though, sorry. Edit: sorry, my comment seems a bit dismissive, but I really do recognize that no good comes from feeding the fire, and I wasn’t trying to weasel out of personal responsibility in that.
