Final answer:
The earliest dwellings in eastern Europe were constructed of timber. Archaeological evidence from eastern Europe also points to the use of mammoth bones, but such structures were less common compared to wood huts used since 380,000 BCE. Norse Timber Architecture was distinctive in medieval northern Europe, focusing on log and stave building techniques.
Step-by-step explanation:
The earliest eastern European dwellings were primarily constructed from timber, as well as other materials like wood, straw, and rock. While archaeological evidence of Paleolithic shelters made from mammoth bones has been uncovered in eastern Europe, these were less common. In general, temporary wood huts have been constructed by humans as early as 380,000 BCE. The simple designs were based on readily available materials, and although stone and brick buildings from later periods have endured, wood structures have mostly disappeared due to deterioration over time.
In northern Europe, particularly in areas like Norway, a period known as Norse Timber Architecture saw the convergence of building with horizontal logs and the stave building tradition. This created a distinctive style of medieval art and architecture, rooting from log house traditions which were essential to early Nordic settlements. Timber, being a widely available resource in these regions, greatly influenced the construction methods and architectural styles of the time.
