In prior years on this blog I identified two Ohio spear point artifacts which are possibly from the "pre-Clovis era" (before about 13,500 years ago) and which may indicate attempts to make the points symbolic icons of the owl.
featured earlier on this blog. This side seems to depict a hooked beak.
Even if the flute channel is not related to the owl symbolism the basal tangs on Clovis points remain as symbolic of the ears of an owl. This may have been done to bring the magic power of the owls' hunting prowess, evidenced by night vision and silent flight capabilities, to the human hunt.
Dr. Bruce Bradley of the University of Exeter has described the relatively fast emerging and short life of Clovis tool kits as a possible cult-like response to the need for an urgent change in established life-ways. One may speculate that the reduction of available megafauna at the terminal Pleisistocene may have triggered the need for a more focused and fully expressed ritualistic symbol-driven hunting system.
If large animal protein, bone and ivory were less available as scavenged items, hunting and the use of spear points may have emerged to continue to maintain elements of the big animal culture. Maybe the 'owl' icon was seen as a way to improve their odds.
According to the BBC series "Planet Earth", elephant night vision is "not much better than our own." This puts elephants at a notable disadvantage when there are hungry predators around, as demonstrated in the series, when a pride of around 30 lions takes down a medium-sized elephant which has difficulty seeing them once it gets separated from its herd.
