The study revealed that chimpanzees and bonobos form social bonds based on the same principles as humans, distinguishing between close companions and acquaintances. This pattern of social organization emerged long before humans appeared and reflects an ancient evolutionary mechanism for optimally distributing attention and resources.
Experiments have shown that chimpanzees can distinguish crystals from ordinary stones and display a special interest in them, examining their geometry and transparency. This behavior is believed to be linked to the ancient roots of symbolic thinking in primates.
A new study has shown that mushrooms play an important role in the diet of some primates in Tanzania, and for baboons, they have become a preferred food source. These findings help us better understand the possible diets of ancient hominids.
A new study has shown that chimpanzees consume a significant amount of alcohol each day by eating overripe fruit. This discovery sheds light on the ancient evolutionary roots of humans' attraction to alcohol.
