Chimps 'raid' fruit to lure mates | |
(1 day later) | |
Experts studying the evolution of human behaviour have discovered chimpanzees will raid fruit to attract a mate. | |
The study found that males will abscond with fruits like papaya from nearby orchards and give it to females. | The study found that males will abscond with fruits like papaya from nearby orchards and give it to females. |
The University of Stirling research was carried out with a small chimp community in the Republic of Guinea in West Africa. | |
The finding is the only recorded example of regular sharing by unrelated non-provisioned wild chimpanzees. | |
Scientists think the chimps use the crop-raids as a way of advertising their prowess to other group members, especially the opposite sex. | Scientists think the chimps use the crop-raids as a way of advertising their prowess to other group members, especially the opposite sex. |
The study, which took place in the village of Bossou in the Republic of Guinea, also found that males mainly shared their spoils with females of reproductive age. | The study, which took place in the village of Bossou in the Republic of Guinea, also found that males mainly shared their spoils with females of reproductive age. |

Lead researcher, Dr Kimberley Hockings from the university's department of psychology said: "Such daring behaviour certainly seems to be an attractive trait and possessing a sought-after food item, such as papaya, appears to draw even more positive attention from the females. | Lead researcher, Dr Kimberley Hockings from the university's department of psychology said: "Such daring behaviour certainly seems to be an attractive trait and possessing a sought-after food item, such as papaya, appears to draw even more positive attention from the females. |
"It is unusual behaviour as even though the major part of chimpanzees' diets consists of plant foods, wild plant food sharing occurs infrequently." | "It is unusual behaviour as even though the major part of chimpanzees' diets consists of plant foods, wild plant food sharing occurs infrequently." |
The study showed that males who shared the most food with certain females, engaged in more consort ships and received more grooming than others, including the alpha male. | The study showed that males who shared the most food with certain females, engaged in more consort ships and received more grooming than others, including the alpha male. |

"It has been proposed that men in hunter-gatherer societies acquire large and risky-to-obtain food packages for social strategising and to garner attention," she added. | "It has been proposed that men in hunter-gatherer societies acquire large and risky-to-obtain food packages for social strategising and to garner attention," she added. |
