The evolutionary relationships concerning the species are actually researched in past times working with morphological methods, but much more not too long ago, molecular scientific tests have enabled the investigation of phylogenetics relationships. in a few species, genetic divergence has been suppressed by the large degree of gene flow among different populations and the place the species have hybridized, huge hybrid zones exist.[8]

Neutering may be the sterilization of animals by means of gonadectomy, and that is an orchidectomy (castration) in canines and ovariohysterectomy (spay) in bitches.
