In prehistoric and protohistoric times, over a period of at least 600,000 years, the area of present-day Poland was intermittently inhabited by members of the genus "Homo". It went through the Stone Age, Bronze Age and Iron Age stages of development, along with the nearby regions. The Neolithic period ushered in the Linear Pottery culture, whose founders migrated from the Danube River area beginning about 5500 BC. This culture was distinguished by the establishment of the first settled agricultural communities in modern Polish territory. Later, between about 4400 and 2000 BC, the native post-Mesolithic populations would also adopt and further develop the agricultural way of life.
