Chimpanzees Help Each Other upon Request
BACKGROUND The evolution of altruism has been explained mainly from ultimate perspectives. However, it remains to be investigated from a proximate point of view how and in which situations such social propensity is achieved. We investigated chimpanzees' targeted helping in a tool transfer paradigm, and discuss the similarities and differences in altruism between humans and chimpanzees. Previous...

that, while humans can do things that fruit flies can't — such as writing a quick guide for Current Biology — fruit flies can also do things that humans can't — such as flying or walking upside down on the ceiling. But rice beats both fruit flies and humans, with 62,435 genes, and it is hard to argue that rice are 3–5 times as complex as humans or fruit flies. So if the sheer number of genes do...
متن کاملTheistic Percepts in Other Species: Can Chimpanzees Represent the Minds of Non-Natural Agents?¤
The present theoretical article addresses the empirical question of whether other species, particularly chimpanzees, have the cognitive substrate necessary for experiencing theistic and otherwise non-natural (i.e., non-physical) percepts. The primary representational device presumed to underlie religious cognition was viewed as, in general, the capacity to attribute unobservable causal mechanis...
متن کاملPost-Conflict Affiliation by Chimpanzees with Aggressors: Other-Oriented versus Selfish Political Strategy
Consolation, i.e., post-conflict affiliation directed from bystanders to recent victims of aggression, has recently acquired an important role in the debate about empathy in great apes. Although similar contacts have been also described for aggressors, i.e., appeasement, they have received far less attention and their function and underlying mechanisms remain largely unknown.

متن کاملAnt-dipping among the chimpanzees of Bossou, Guinea, and some comparisons with other sites.
We present a detailed study of ant-dipping among the wild chimpanzees (Pan troglodytes verus) of Bossou, in southeastern Guinea, West Africa. Observations suggest a strong influence of prey (Dorylusspp.) characteristics, including aggressiveness and/or gregariousness, on tool length and technique employed by the chimpanzees. Bossou chimpanzees exhibit two ant-dipping techniques: 1) direct mouth...
