Final answer:
The early 1900's descriptions and perceptions of Neanderthals were erroneous due to media stereotypes, Eurocentric bias, and limited bone findings. Recent DNA studies have provided more accurate information about Neanderthals.
Step-by-step explanation:
The early 1900's descriptions and perceptions of Neanderthals were erroneous due to various factors. First, media and entertainment created false stereotypes and misconceptions about Neanderthals, portraying them as brutish cavemen. Secondly, European scholars at that time believed in Eurocentrism and assumed that Europe was the most advanced part of the world, leading to biased interpretations of Paleolithic art. Thirdly, limited bone findings and lack of genetic evidence resulted in a poor understanding of Neanderthals, until DNA studies in recent years revealed their genetic connections with modern humans.
