If you would but read Templeton's article. Replacement is ruled out at a p< 10^-17.  Here is the full quote:

The null hypothesis that none of the inferences involving Eurasian populations (Figs. 7, 8) are older than 1.05 MYA is rejected with = 0.035 when MX1 is excluded (Templeton, 2005). Hence, the expanding African populations with the Acheulean culture did not totally replace the Eurasian populations they encountered, but rather interbred with at least some of them. Similarly, themost recent out-of-Africa expansion is no older than 0.177 MYA with 99% confidence. Excluding MX1, the null hypothesis that no other event or process involving Eurasian populations is older than 0.177 is rejected with a probability of less than 10^-17. Hence, the recent out-of- Africa replacement hypothesis is overwhelmingly rejected. p. 49

If I haven't understood what you mean by near null, please define it.

 I posted here earlier that Templeton calculated that if all the genetic expansions, seen in his 25 analyzed loci, resulting in 15 expansion events, occurred at the same time, it would have a probability of 1 chance in 3.89 x 10^-15. 
That probability rules out total replacement.  I guess I will repeat my other post because there was clearly some trouble with distribution.  One of my accounts (yahoo) got the report the other (entouch) didn't.   I don't know how to answer it other than with what I already posted.

He doesn't mention them so I guess he handles them in the same way that the YECs do--common design. Hugh has God create each and every species. That is something that one has to read closely to figure out.
There is still such an event whether it's

Yeah, I chose my poison--concord with the genetic evidence and maintain Adam as the human ancestor. Dick chose his.  But, if everyone here is so eager to have allegories and accommodations, why not have an accommodation to tell the Adam story in a modern setting (modern being 3000 BC). Of course no one would think of doing such a ridiculous thing as saying that God could merely accommodate the setting of the story because that would be too close to concordism which we all know is false. God can accommodate all sorts of false science, but NEVER the setting of the story.
BTW, what do you do with religious altars prior to 10,000 years ago? We can deny it but it was there as far back as 425,000 years with some hints even further back.
