| highwaystar101 said: Humans only used the dogs that were best suited for the job they had domesticated them for, the others didn't survive, this is evolution that is extremely rapid. Dogs that were used for protection became increasingly vicious, dogs that were used to plough fields became big and strong and so on. All this change has happened over just a few millenniums. |
The rapidness was surely because of selective breeding, a strong dog was more then likely able to produce strong offspring, breed a strong dog and bitch together and you've got strong offspring, the weak dogs are seen as inferior and either disposed of do not breed. Just like horses and greyhounds, breeding fast strong runners with females to produce fast runners again.
Oh on the Liger and a Tigon thing, I think how they are named is based on which species is the female and which is the male (so male tiger breeds with female lion and vis versa). Not sure which way round it is though.
Hmm, pie.
