Since publication of the 2015 Great Ape Health Guidelines, great ape tourism has continued to gain in popularity, and landscape conversion continues on a steep trajectory. In addition, there has been a tremendous amount of new scientific research on pathogens that infect wild great apes. Furthermore, the world experienced epidemics of Ebola (in West Africa from 2014–2016 and in eastern Democratic Republic of the Congo (DRC) from 2018–2020) and the COVID-19 pandemic (2020–2023).

L'intelligence des singes superieurs

1927 Guillaume, P. | Köhler, Wolfgang |
P. Guillaume traduit l'ouvrage de W. Köhler. Ce travail est très important dans l'éthologie, la psychologie cognitive et l'étude des singes anthropoïdes. Il montre qu'il n'y a pas de ligne de démarcation absolue entre l'espèce humaine et son plus proche parent vivant.

1928 Bingham, Harold C. (Harold Clyde) |
