Kanzi strikes again

Recommended Posts

In this publication the authors report the extensive creation of flint tool by the famous bonobo Kanzi.

 

Using direct percussion, language-competent bonobo-chimpanzees Kanzi and Pan-Banisha produced a significantly wider variety of flint tool types than hitherto reported, and used them task-specifically to break wooden logs or to dig underground for food retrieval. For log breaking, small flakes were rotated drill-like or used as scrapers, whereas thick cortical flakes were used as axes or wedges, leaving consistent wear patterns along the glued slits, the weakest areas of the log. For digging underground, a variety of modified stone tools, as well as unmodified flint nodules, were used as shovels. Such tool production and utilization competencies reported here in Pan indicate that present-day Panexhibits Homo-like technological competencies.

Beautiful and amazing! To think that one of the defining attributes of humans is tool use. But the more we look, the more we find that we are not so unique in this aspect. Some view science as a sterile endeavor, yet the fruit is filled with awe and wonder.

The average syllable/word count is higher than average, as is

the sentence length.

When businesses invoke the "protection of consumers," it's a lot like

politicians invoking morality and children - grab your wallet and/or

your kid and run for your life.
