▪ Abstract In the 1970s, researchers provided the first detailed descriptions of intergroup
conflict in chimpanzees. These observations stimulated numerous comparisons between …

Among primates, intense paternal care is manifested in only a few distantly related species,
including humans. Thus, neither purely phylogenetic nor socioecological hypotheses can …

The chimpanzees are the closest living evolutionary relatives to our own species, Homo
sapiens. As such, they have long exerted a fascination over those with an interest in human …

This second edition reviews the new research findings and theoretical advances on fathers,
families, child development, programs, and policies that have occurred in the past decade …

Referential models based on extant African apes have dominated reconstructions of early
human evolution since Darwin's time. These models visualize fundamental human …

Male chimpanzees, Pan troglodytes, engage in cooperative territorial defence and
sometimes kill members of neighbouring communities. Observations of intergroup …

In this paper, an intelligent optimization technique, namely Bonobo Optimizer (BO), is
proposed. It mimics several interesting reproductive strategies and social behaviour of …

Several elements of the Ardipithecus ramidus foot are preserved, primarily in the ARA-VP-
6/500 partial skeleton. The foot has a widely abducent hallux, which was not propulsive …

A crucial step in recent theories of human origins is the emergence of strong pair-bonding
between males and females accompanied by a dramatic reduction in the male-to-male …

Long-term field research has revealed that male chimpanzees, Pan troglodytes, affiliate and
cooperate in several contexts. Assuming close genetic relationship among males, affiliative …
