can you not fcking read.<quoted text>
In order to be considered a new species it should be not able to interbreed successfully with the other sub-population(s) of the ancestral species.
"actually to be considered a new species it has to be able to breed with another(same hybrid) and produce fertile offspring and to be able to produce a stable population" is utter crap and rubbish and only to be produced by a layman who has not the slightest understanding of biology or evolution theory.
Speciation, as requested, has been demonstrated.
The rest is straight layman's tattle.
Rattle the tattle.
actually to be considered a new species it has to be able to breed with another(same hybrid) and produce fertile offspring and to be able to produce a stable population. a mule cannot breed another mule and produce fertile offspring to be able to create a stable population.so technically it should not be considered a new species from a scientific stand point. it should be considered nothing but a hybrid same as ligers and tigons.
let me add to this. not all hybrids are sterile. some hybrids can reproduce and create a stable population. but that can happen in just a few generations which is not the many many thousands/hundred thousands of years that the theory of evolution predicts that it requires to for a species to become genetically different from its parent(s) species to form a population of a new species.
