Formerly the bonobo was known as the "pygmy chimpanzee", despite the bonobo having a similar body size to the common chimpanzee. The name "pygmy" was given by the German zoologist Ernst Schwarz in 1929, who classified the species on the basis of a previously mislabeled bonobo cranium, noting its diminutive size compared to chimpanzee skulls.
Bonobo (video) Female chimpanzee at Tobu Zoo in Saitama, Japan. Anatomical differences between the common chimpanzee and the bonobo are slight. Both are omnivorous adapted to a mainly frugivorous diet. [49] [50] Yet sexual and social behaviours are markedly different.
Duplications of small parts of chromosomes have been the major source of differences between human and chimpanzee genetic material; about 2.7% of the corresponding modern genomes represent differences, produced by gene duplications or deletions [failed verification], since humans and chimpanzees diverged from their common evolutionary ancestor.

According to Meinelt, it was an intentional decision by zoo officials to bring in bonobos rather than chimpanzees, recognizing the need to raise awareness about the lesser-known species and to ...
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
But even among species in the same genus, such as bonobos and chimpanzees (who likely separated only 1 to 2 million years ago), differences between Y chromosomes were stark.
The split between the common ancestors of the chimpanzee and bonobos then took place about 1.5 to 2 million years ago with the two lineages giving rise to the two current extant species. In the past, bonobos were incorrectly relegated to subspecies status within the species chimpanzee. It is now understood that bonobos are an entirely different ...
