Differences Between Wolves & Dogs?

[Catherine]

Humans have tried to intervene and create diversity in animal species. It has worked with dogs. The mutations are naturally occurring and we worked with them to produce the different breeds of dogs. We have produced some variations in cattle, sheep and goats. We have a range of chicken breeds. Cats have resisted our efforts to change them. There are some odd variations like the Scottish fold, but nothing like the variations found in dogs.

The big question is why dogs have such a wide range of sizes and shapes. Humans have helped, but we only worked with what was happening.
Now we can do gene editing and splicing, but most dog variations happened a long time ago. I will see if I can find anything on this subject.
Wolves have shown little variation ever.
