In creating the studies on kinship specific to humans, anthropology has particularized human reproduction as a social and cultural construct that distinguishes it from the reproduction of other species. But have the kinship systems of human groups been thought out in isolation, or have they integrated the observation of the modes of reproduction and the relationships that generate them in other species ? The question that leads this article is how human cultures are inspired by ecosystem reproduction to represent their own kinship. In the Arab and Muslim world, and in a very significant way in Morocco, figures that articulate the reproduction and the filiation of the trees, to those of humans, are supranatural entities called djinn. It is therefore by following the track of the djinn that this article intends to explore the question of the kinship of trees, taking the argan tree as an example. The argan tree has an enormous cultural value which is also proof of a close relationship between the human populations and this tree, which is articulated thanks to the reference to the djinn. For the Berber-speaking populations, there is indeed a link between the way in which the trees are affiliated and the way in which they themselves are affiliated. The interweaving of kinship and tree populations suggests the strong bind between the mutually assured continuation of beloved ecologies and culture, with the tree as a widespread defining symbol of this lived meaning
