African elephants show high levels of interest in the skulls and ivory of their own species
Open accessAbstract
An important area of biology involves investigating the origins in animals of traits that are thought of as uniquely human. One way that humans appear unique is in the importance they attach to the dead bodies of other humans, particularly those of their close kin, and the rituals that they have developed for burying them. In contrast, most animals appear to show only limited interest in the carcasses or associated remains of dead individuals of their own species. African elephants (Loxodonta africana) are unusual in that they not only give dramatic reactions to the dead bodies of other elephants, but are also reported to systematically investigate elephant bones and tusks that they encounter, and it has sometimes been suggested that they visit the bones of relatives. Here, we use systematic presentations of object arrays to demonstrate that African elephants show higher levels of interest in elephant skulls and ivory than in natural objects or the skulls of other large terrestrial mammals. However, they do not appear to specifically select the skulls of their own relatives for investigation so that visits to dead relatives probably result from a more general attraction to elephant remains.

African elephants are more interested in the bones and tusks of dead elephants than similar-sized bones of other species.
“Experiments with artificially placed bones confirm that African elephants are more interested in the bones and tusks of dead elephants than similar-sized bones of other species.”

Elephants in McComb et al. (2006) showed more interest in ivory than in skulls.
“Interestingly, elephants in this study showed more interest in ivory than in skulls.”

The skulls in McComb et al. (2006) were washed and moved to a different location, and thus may have been lacking cues (e.g., olfactory, spatial) that would be important for individual recognition.

McComb et al. (2006) found that African savanna elephants were more interested in elephant skulls and ivory than wood, and more interested in elephant skulls than buffalo and rhinoceros skulls. However, when presented with skulls from one kin (matriarch) and one nonkin, elephants did not display different levels of interest.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
