SPEAR NOT  A new analysis of obsidian artifacts from Easter Island indicates that these finds served as tools for planting and other daily activities. Some researchers have portrayed these implements as spearpoints that were used by warring island groups before Europeans arrived in the 1700s.

Sharpened stones previously viewed as spear points wielded by warring Easter Islanders actually served as general-purpose tools, researchers say.

Early European visitors to Easter Island, also known as Rapa Nui, wrote in the late 1700s that the islanders carried spears topped with sharp, triangular pieces of glassy lava, or obsidian. In the past 20 years, some researchers have suggested that fighting among spear-bearing groups — following the leveling of resource-rich palm forests around 1550 — destroyed Rapa Nui civilization before Europeans arrived.
