[subroutine]

You've clearly mistaken my primary qualm. I'm not saying that Orangutans are not fully capable of the things these authors claim. Moreover, I'm not even saying bees aren't capable of conveying learned information. On the contrary, my position is that everything from bees to orangutans to humans have this capacity. In fact, I see this type of communication happening between lots of animals. It seems more like a ubiquitous capacity, than a uniquely human capacity. The authors of this paper don't agree though; instead they are promulgating the idea that "Orangutans are the only great apes besides humans to 'talk' about the past".

This is FALSE

*Chimps used intentional gestures to coordinate with an experimentally-naïve human to retrieve hidden food. In each trial, Experimenter #1 hid a food item anywhere from 3 m to 26 m from the outdoor enclosure under natural cover (e.g. log, soil, leaves, branches) in a trial-unique location in the surrounding woodland, whilst the chimpanzee was watching. The experimenter hid the food and concealed any signs of the hiding place (e.g. breaking up of soil). The chimpanzee could not enter the woodland itself. In order to retrieve the food, the chimpanzee had to recruit the assistance of an uninformed person (Experimenter #2) and direct him to the food item.

The chimpanzees dynamically and flexibly modified their intentional gestures in relation to the naïve experimenter's search efforts towards the hidden food, and successfully guided experimenter #2 to the food item.

You can see in the supplementary videos that experimenter #1 finishes hiding the food at time 4:19...

The chimp doesn't greet experimenter #2 until after 4:30 (see same screenshot above). If Orangutans are the only great apes besides humans to ‘talk’ about the past, how the hell is this Chimp communicating with a human to retrieve food it saw buried at some time in the past?
