It’s possible to know something happened without knowing exactly when. If you see milk on your kitchen floor for example, you know it spilled from something even if you’re not sure if it spilled from a jug or glass or when it spilled. And by looking at genetics and the (I use this term loosely due to the geological recency) fossil record, they can know dogs and modern wolves had a common ancestor even if they’re not exactly sure when.So scientists don’t have any supporting evidence, but they’re sure of their conclusions?
Wolves and dogs are separate species. I think dogs were domesticated by the behavioral adaptation of their species, not evolution (and were created for this purpose).
Kind of like putting together a puzzle. After a while you start to know what the picture is even if there are still missing gaps you don’t know about for sure because you haven’t found the pieces.
And with dogs, I’m illustrating a principle. The traits humans liked were the ones that got passed down. Those minor differences amplified over multiple generations and a paddle is different from a golden retriever which is different from a great dane.
In the wild, other pressures such as getting food or surviving climate cause only certain individuals to survive and pass down their genes.
