New Species

[AZ]

Hi,
I am looking for any publication, preferably on the Internet, 
supporting hypothesis of creation of new species in a lifetime
of ONE generation.  New species are created NOT over 
millions, or thousands or hundreds or even tens of 
years, but within one generation of a given species. A spontaneous
burst/mutation of young members of the same generation into new 
species.  

Appreciate your respond to this posting.

Regards, AZ
