I bet some of you did not know this. Domestication of the following animals have resulted in the transmission of microbes into humans that still affect us today:

Wild pig: influenza
Wild bovine: tuberculosis, measles, small pox
Wolf: rhinovirus (common cold), rabies
Horse: rhinovirus (common cold - different strain)
Civet: coronavirus (SARS)
Birds: influenza
Deer: Lyme disease
Sheep and other livestock: Anthrax, Creutzfeldt–Jakob disease (caused by a protein!)
Rodents: Plague
Consumption of primate bush meat: HIV, ebola

From the above list, the rhinovirus from the wolf seems to be the oldest evidence of disease that jumped from other animals to humans. This specific jump is thought to have occurred during the last ice age (~ 30kya) in East Asia.

I'm imagining that we also required some good microbes from them.

This came from domestication? Didn't the Plague come from insects that infected Rats who already lived in very unclean streets quite literally covered in faeces? I recall one of the reasons it vanished again was because we became much better hygienically. I'm not even sure we had domestic rodents back then, let alone to the extant of killing massive amounts of people like this.

In fact, haven't all of these diseases been in nature for long periods of time? Even before certain species were domesticated? I believe that domestic animals just tends to carry these diseases more often than their wild counter parts, but for some odd reason seems to live quite well with it.

The best thing about domestication is that we do not have to hunt wild animals to eat some animal proteins.

Deer give us Lyme disease, but not the domestication of deer. Anthrax too is a natural thing that stirs to the surface during drought. Plague as well obviously. Not about domestication.

Everything i know about being wrong makes me question the other stuff, I have to say.

In wild the basic rule is 'Survival the fittest' means every generation is fitter than their preceding one but in domestication every generation is weaker than preceding one because in-human(closed room) conditions the animals live.

The fat content increase in their body,weak bones,low immunity and so diseases one after another.

@Satya: Domestication is the best thing that could happend to a species. Please compare how many domestic cattle are today and how their wild ancestor(s) are all extinct. How many dogs we have today and how rare are the dingoes, wolves, coyotes, jackals, and foxes. And do not forget that domestication is a reciprocal process. People are a domesticated mammal species too, because they were influenced by their domestic plants and animals.

Yes, but we are not live all our life in a closed room like factory-animals and as an intelligent animal we take care our-self.

But who killed the Ice Age megafauna? Wild cattle are the last large mammals who went extinct of natural causes. It is a good thing that the people have domesticated them before they disappear.

Who killed Dinosaur? Who said wild cattle will disappear?

FYI I eat animals and want to rise,exploit and kill them humanely not like factory products.

I do not know who killed the dinosaurs. But I do not think the humans killed the Ice Age megafauna. And the wild cattle, who were a component of the Ice Age megafauna, are now extinct, except for the domesticated ones, who survived extinction. So, for the cattle, domestication saved them from extinction. Same is the case with dogs and cats, compared with their wild ancestors.

Even today Wild Water buffalo exists-- of course few 1000's.

Dogs are domesticated Wolves and Wild Cats exists all over the world still!

This is wrong, quite awkwardly wrong. Sure, you will find poorly bred examples and quite a lot of them, but you will also find rare cases of selective breeding just as good, if not actually better than that of survival of the fittest. Some domestic dogs have even gone through a combination of selective breeding and survival of the fittest. it is not always the strongest that breeds in the wild, nor will the next generation always be stronger, but if you take dogs from actually good working lines, you will discover that they too take the best of the best genetics, temperaments and anatomy and breed them further. We don't have dogs significantly physically stronger than Wolves without reason.

Ok. But how do you know the house dogs and house cats are descended from the living species of wolves and wild cats? Maybe their real ancestors are long gone.
