@Leo Greer you are confusing evolution with selective breeding in your example of the great Dane.
Wolves didn't evolve into the domestic dogs we have today they were breed to have these traits.
Selective breeding is where you take an animal with the traits you want and breed it with a similar traited animal to produce offspring more likely to take the parents traits, repeatedly doing this ends up with creating the breeds we know today. People are now creating miniature husky breeds through this process as well.
Evolution is essentially being born with a genetic variation/mutation at random. This can have 3 outcomes in the wild.
1. The variation causes a significant advantage to the offspring causing it to dominate natural resources and/or breeding driving the original variation to die out.
2. No advantage or disadvantage, the variation blood lines lives on and simply becomes a variation/subspecies. (Best comparison is how some peoples earlobes connect to thier head and some have dangling earlobes or people with webbed toes)
3. The variation actually hampers it's development and ability to survive and the bloodline dies out.
If people died out and couldn't disrupt the natural order it's likely that a lot of existing domesticated animals would evolve vary slightly. (Except cats as they already considered themselves gods and are stubborn as hell)(disclaimer cat part is a joke about not evolving).
Also don't forget evolution may not result in a physical outside appearance change but could be internal as well a lot of people only think of external changes.
In recent times document evolution has been limited but that's for good reason, we as a species have dominated, controlled and destroyed the planet, by the time we started to properly document every trait and have been able to test DNA sequences we've nearly wiped out most wildlife on the planet. It doesn't stand a chance of adapting and evolving as we are killing it too fast and driving it to extinction.
Another good read is about the English red Vs American grey squirrel, when the American squirrel was introduced with its genetic variation it's caused the red squirrel population to dive as it could outcompete for resources Yet besides colour most people would say they are the same from just looking at them. Yet they are both still squirrels it's just genetic variations.
But anyways let's go back to shooting little plastic balls at each other for fun even though it's terrible for the wildlife. (This is my biggest issue with the sport we need to become more environmentally friendly quick)
