Answer :

the least likely result of speciation from teh possibilities you presented would be a0 random mating between members of the species. 

all species work on the same wavelength when it comes to mating - it's survival of the fittest, and every male wants a healthy female to bear his offspring, and every female wants a strong male to protect that offspring. they don't have babies just for the heck of it :)
