What is the notable characteristic of Catalhoyuk established around 7000 BC?

The notable characteristic of Catalhoyuk, established around 7000 BC, is that it is recognized as one of the largest Neolithic settlements, spanning approximately 13 hectares. This size indicates its significance as an early urban center where people lived in close-knit communities. The layout of Catalhoyuk consisted of tightly packed mud-brick houses, creating a unique architectural environment that reflects the social and communal lifestyle of its inhabitants. The density of the settlement suggests advanced social organization and the emergence of complex society typical of Neolithic cultures.

The other options, while interesting aspects of urban development, do not apply to Catalhoyuk. The settlement is not known for having a formal legal code, an advanced educational system, or monumental temples akin to later civilizations. Instead, it is notable for its domestic structures and the communal lifestyle, illustrating the important transition from nomadic to sedentary living during the Neolithic period.
