evidence: Humans (Homo sapiens) make art. We do this for many reasons and with whatever technologies are available to us. Recent research suggests that Neanderthals also made art. [...] Although the Paleo-Indians who migrated to America from Asia (across the Bering Strait — a land bridge that once joined present-day Alaska and eastern Siberia) during the Pleistocene Epoch (Ice Age) did not leave behind a written (or even a large material) record, they can be identified by specific toolkits. Clovis points, for example, reveal technologies of hunting and processing meat, as well as crafting a sharp point from available resources. Workers used a hard rock to chip flakes from a softer one, shaping it into a sturdy point that could be used by hand or fastened to a wooden spear. These tools reveal that Clovis people were hunter-gatherers, relying upon big game. As ice thawed, toolkits diversified. Later Archaic people left behind wooden fishing spears reflecting an expansion of hunting and diet, possible boat technology, and a variety of specialized stone tools. But the most significant development in the Americas was the start of agriculture which fundamentally altered lifestyles of people throughout the hemisphere.
