You have got to be kidding, to define kind is as difficult as to
define species. The dividing line would be breeding in nature.
One of Lenny Flanks pet peeves is New Jersey treefrogs, is a case in
point, there are two species of tree frogs that in appearnce they are
Identical. They do not, will not breed in nature, nor captive. He use
this example to stress a point. Don't remeber what his point was. But
I use to tease him about to the point of fustration :-)

does it happen.. yes, Pittbull is a point in case. Does speciation
have a Limit? yes it does. a Dog, will still remain a dog, etc.

No it's not. Jackals, Coyotes and Dogs are three species in the Canine
Genus. They are highly cross fertile producing very fertile hybrid
offspring. The offspring can mate with each other or with either of the 2
species that produced them. Many plants are fertile across Family and
Genus.
