You failed.It's well defined. In fact it's the first definition in the dictionary... It's your term species that has 26 separate definitions and is not well defined to the extent they admit to having a species problem...
Definition of SPECIES
a : kind, sort
b : a class of individuals having common attributes and designated by a common name specifically : a logical division of a genus or more comprehensive class confessing sins in species and in number
c : the human race : human beings —often used with the survival of the species in the nuclear age
d(1) : a category of biological classification ranking immediately below the genus or subgenus, comprising related organisms or populations potentially capable of interbreeding, and being designated by a binomial that consists of the name of a genus followed by a Latin or latinized uncapitalized noun or adjective agreeing grammatically with the genus name
(2) : an individual or kind belonging to a biological species
e : a particular kind of atomic nucleus, atom, molecule, or ion
Once again, how would you tell if two different groups were the same "kind" or not. It is a simple question, why can't you answer it? If your beliefs are true there should be a simple way to tell.
