On the psychological origins of tool use
2022, Neuroscience and Biobehavioral ReviewsElephants evolved strategies reducing the biomechanical complexity of their trunk
2021, Current BiologyCitation Excerpt :Remarkably, the elephant trunk can perform very delicate tasks such as manipulating a single blade of grass, but it is also capable of carrying heavy loads up to 270 kg.2,3 The proboscis serves elephants in multiple additional functions: breathing, olfaction, mechanosensation, vocalization, posture-based communication, siphoning/spraying water, sprinkling dust, and tool handling.2–12 In principle, a muscular hydrostat could exhibit a virtually infinite number of degrees of freedom.
Is there a “g-neuron”? Establishing a systematic link between general intelligence (g) and the von Economo neuron
2021, IntelligenceCitation Excerpt :Wild chimpanzees, for example, use sticks to obtain manually inaccessible food sources such as ants or honey and have been observed to combine the usage of two separate tools when foraging (Boesch & Boesch, 1990). When plagued by flies, Asian Elephants modify long bushy branches, rendering them ideal for fly-swatting (Hart, Hart, McCoy, & Sarath, 2001). Moreover, there are reports of captive elephants, selectively damaging electrified fences with rocks or “muting” bells placed around their necks by clogging them with clay, allowing the animals to depredate cultivated banana groves unnoticed (Holdrege, 2001).
