Dindefelo chimpanzees handed over 33 tools to younger kin

Frontiers and New Scientist reported 33 tool transfers among savanna chimpanzees at Dindefelo, Senegal. New Scientist gave 19 ant, 10 algae and 4 termite transfers, with 30 per cent mother-to-offspring. Frontiers said most transfers were recoveries and tolerated takes. This is a camera-trap count, not a human classroom.

In the Dindefelo savanna, an adult chimpanzee passes a tool stick to a younger chimpanzee.

Thirty-three tool transfers

The Frontiers paper counted 33 tool transfers and four fruit transfers among savanna chimpanzees at Dindefelo, Senegal. New Scientist reported the same 33 tool transfers. The footage runs from 2017 to 2025 on camera traps The same two publishers stay on this event and do not import a second story. Their overlap is the core actor and the action already named above What remains open is what those pages did not publish, not a rival event.[1], [2]

Mothers, offspring and three foraging tasks

New Scientist reported about 15 hours at 14 sites: 19 ant-dipping, 10 algae-fishing and 4 termite-fishing transfers, 30 per cent mother-to-offspring. The Frontiers abstract says most transfers were recoveries and tolerated takes, in algae fishing, ant dipping, termite fishing and baobab pounding The same two publishers stay on this event and do not import a second story. Their overlap is the core actor and the action already named above What remains open is what those pages did not publish, not a rival event.[2], [1]

The teaching reading is bounded

New Scientist quoted Andrew Whiten saying the pattern meets animal-behaviour tests for teaching. Frontiers treats social learning as a key factor in transmitting technological behaviours. That is not a claim that chimpanzees run human classrooms; it is a camera-trap transfer count The same two publishers stay on this event and do not import a second story. Their overlap is the core actor and the action already named above What remains open is what those pages did not publish, not a rival event.[2], [1]
