Prizes for finding specific things in specific years don't reflect the structure of how ancient archaeology actually works. Picking domesticated horses as a hopefully representative example:

* The earliest clear, irrefutable example of domesticated horses - horses and chariots put into a grave together - is from 2000 BCE.

* Most sources are confident horses were domesticated by 3000 BCE.

* There's archaeological evidence for domestication as early as 3500 or 4000 BCE.

* The closest known wild relative of the domestic horse diverged genetically tens of thousands of years ago. But it's believed that this was a natural event, and Equus ferus caballus was wild for some time before humans domesticated it and drove the wild stock extinct.

If there's a prize for showing horses were domesticated west of the Caspian see before 3000 BCE, is it awarded or not? I don't know and I don't see any great way to decide.
