I think I need clarification here. Many of today’s dog breeds have only been developed within historical times, many within the last few hundred years. So these dog breeds were certainly not created as is. The same can be said of many domestic varieties of animals and birds. Examples of observed speciation are rarer but there probably are a few examples; the London Underground Mosquito is a possible one.
Perhaps what you’re saying is that we can observe new varieties and species appearing in the created kinds? E.g. the London Underground mosquito is still a mosquito. I would agree with that.
