Final answer:
The sudden emergence of domesticated animals and crops in southeastern Europe is indicative of the diffusion of Near Eastern agricultural practices during the Neolithic Revolution.
Step-by-step explanation:
The sudden appearance of fully domesticated sheep, goats, wheat, and barley in southeastern Europe, along with specific Near Eastern cultural traits, is evidence of an agricultural diffusion that occurred during the Neolithic period. This diffusion is thought to have begun as early as 7000 BCE.
The domestication of plants and animals likely spread from the Near East, regarded as one of the primary centers of agriculture, to various regions including Southeastern Europe. Agriculturists may have adopted cultivation techniques from the Near East, and over time, developed and adapted these techniques to their local environments.
The Neolithic Revolution denotes a significant shift from hunter-gatherer societies to settled agriculture. In southeastern Europe, this transformation included the introduction of sheep, goats, and crops like wheat and barley. This process of agricultural development eventually facilitated the rise of more complex societies and the eventual emergence of statehood.
