How did dogs becomedomesticated and where did thebreeds come from?
I've been looking online to find out how dogs were domesticated. It seems it happened about 10-15,000 years ago. Anyone have any more detailed information about this? Also, where did all the breeds come from? Prior to domestication, were there packs of Great Danes and Chihuahua's running around in the wild? Or were the breeds created by mixing different traits of various wolf species?
The domestic dog is a man-made species that has never existed in the wild. There were never packs of Great Danes or Chihuahuas running around in the wild. Domestic dogs are descended from the grey wolf, which was originally domesticated to aid our ancestors in hunting. Through thousands of years of selective breeding, we produced all the hundreds of different dog breeds we have today. The reason there are so many and such variation in size and appearance is that the different breeds were created for different purposes - hunting, guarding, fighting, tracking, herding, lap-dogs, etc. Therefore large breeds were developed for jobs such as guarding and fighting, whilst small breeds were developed just to be kept as house pets, or to follow small animals underground.
What did cats first look likebefore humans domesticatedthem?
And what country where they first founded in? Are there any cats (of the same domesticated species) that still live in the wild?
The domestic cat is believed to be descended from the African wildcat, Felis silvestris lybica. It is about the same size as a domestic cat and looks pretty much the same, though of course without the colour variations and different coat lengths - it is generally a sandy colour with some darker striping. It is common across much of Africa.
What are your thoughts ondomesticated reptiles?
I didn't say captive, I said domesticated. Captive breeding is selecting for traits which are the opposite of what nature selects for--unusual colors for example. A high yellow albino ball python with pied markings would scream "Here's your lunch!" A super giant designer leopard gecko would stand out like the broiled scallop on an appetizer tray of cocktail franks to a hungry predator. The changes we select for in captive breeding are not all readily visible. Animals which have less natural wariness breed more freely in captivity, passing this trait, which would get them quickly killed in nature, on to their offspring. It's the same selective breeding process which turned wolves into dogs and aurochs into cattle. We are on the frontier of creating new domestic species with some of our captive bred reptiles. I don't see this as a bad thing. Our pets might someday be reverse selected to restock a disease or hunting depleted wild population. What are your thoughts?
I don't know that it's much different than what our anscestors did with dogs and cats. Breeders are selecting traits that have more "appeal", whether it be brighter coloration or just "something different than what everyone else has". The prices they get for the animals shows there is a market for them. Personally, I like the "wild" colorations. I've taught in a number of settings and if I want to talk camoflage and natural behaviors of these animals, it's harder to do if all you have are "sunfire" bearded dragons and "tangerine" leopard geckos. As a pet, I don't think the latest designer colors affects the personalities as much as regular interaction with humans from the time they're young animals. Of course, the designer colors are mostly in animals with more docile personalities to begin with. I don't know that the trend for lighter/brighter coloration will be an advantage to replacing wild populations. Albinism and lighter colors are for the most part recessive characteristics, and, as you pointed out, make the animals more visible to predators. Behavior is mostly instinct, but if breeders select the most passive/docile animals for breeding, this may, over time, reduce the natural wariness and aggression they would need to compete with the remaining wild members of their own species. With all this said, I'm not against selective breeding for the pet trade - I just think that there's value in keeping natural traits as well.
