The canine genome has been especially difficult to engineer and replicate – but its close similarity to the human genome means it has long been the prize of geneticists.
Now the Chinese success has led to fears the same technology could be used to create weaponised super-humans – typifed in Marvel Comics by Captain America and his foes.
China have begun to breed ‘super dogs’ with twice the muscle of a normal dog
He told express.co.uk: “It’s true that the more and more animals that are genetically engineered using these techniques brings us closer to the possibility of genetic engineering of humans.
“Dogs as a species, in respect of cloning are very difficult, and even more difficult to clone human beings.
“There’s no medical case for it, the scientists are interested in being the first person in the world to create a genetically engineer child.
In terms of genetic engineering we will be seeing this more and more
“That does set us on the road to eugenics. I am very concerned with what I’m seeing.”
An army of super-humans has been a staple of science fiction and superhero comics for decades – but the super-dog technology brings it closer to reality.
The Chinese researchers first self-bred cloned dog was named Little Long Long.

The advance genetic editing technology has been touted as a breakthrough which could herald the dawn of ‘superbreeds’, which could be stronger, faster, better at running and hunting.
The Chinese official line is that the dogs could potentially be deployed to frontline service to assist police officers.
Dr Lai Liangxue, researcher at Guangzhou institute of biological medicine and health, said: “This is a breakthrough, marking China as only the second country in the world to independently master dog-somatic clone technology, after South Korea.”
