An observant hunter first dug up a cocoon from under the soil of the host plant, which he broke open and took out the larva from within. He rolled the larvae between his fingers, rubbing its skin against a stick he used as a pestle, and then extracted its tissue in one of his special tools -- an old giraffe or kudu knuckle bone, where he could mix it with the rest of the ingredients. These included a chewed bark of a particular pea flowering plant species and the beans from others. Although nowadays many San tribes that have used bowhunting and poison arrows in the past have abandoned them due to restrictions, modern tools and change of lifestyle in general, the familiarisation, adoption and development of poison weapons dating back to Ancient times are excellent examples of the cognitive shifts in human evolution.
