GEO Reportage - Les derniers #orangs-outangs de #Sumatra
https://www.arte.tv/fr/videos/045490-000-A/geo-reportage/

Il ne reste plus que 6 000 orangs-outangs à Sumatra. Selon les projections les plus pessimistes, les chances de survie de l'espèce sont hautement compromises. L'habitat #naturel des #singes recule au profit des plantations de palmiers à huile qui recouvrent environ 70 % de l’archipel indonésien.

Docu de 2011, semble-t-il. Qu'en est-il depuis.... :(

J'en trouve un sur yt, avec le même #scientifique. Visible hors Europe, donc.

It's the same scientist that we see in the English docu, that I put you so that you can see the link.

Scientists Investigate Stone Tool Making and Using Abilities in Orangutans
Early stone tools represent one of the most important technological milestones in human evolution. The production and use of sharp stone tools significantly widened the ecological niche of our ancestors, allowing them to exploit new food resources. However, despite their importance, it is still unclear how these early stone technologies emerged and which behaviors served as stepping-stones for the development of systematic stone tool production in our lineage. One approach to answer this question is to collect comparative data on the stone tool making and using abilities of our closest living relatives, the great apes, to reconstruct the potential stone-related behaviors of early hominins. To this end, a team of researchers from the University of Tübingen, the Max Planck Institute for Evolutionary Anthropology, the University of Barcelona and the University of Oslo tested both the individual and the social learning abilities of orangutans (Pongo pygmaeus) to make and use stone tools...

Orangutans Observed Using Hammer Tools to Crack Nuts
New research from the University of Tübingen demonstrates that nut-cracking can emerge in Sumatran (Pongo abelii) and Bornean (Pongo pygmaeus) orangutans through individual learning and certain types of non-copying social learning.
