Africa-Press – Guinee Equatoriale. <\/strong><\/span>Les rhinoce\u0301ros ont de plus petites cornes qu\u2019auparavant, ce phe\u0301nome\u0300ne est du\u0302 au braconnage, selon une e\u0301tude scientifique qui dresse un bilan triste de la situation.<\/p>\n

Les cornes des rhinoce\u0301ros ont sensiblement diminue\u0301 en un sie\u0300cle et quart, selon le re\u0301sultat d\u2019une e\u0301tude scientifique publie\u0301e dans le journal People and Nature.<\/p>\n

L\u2019e\u0301tude s\u2019appuie sur des photos de quatre-vingts rhinoce\u0301ros de cinq espe\u0300ces modernes (noir, blanc, indien, javanais et sumatran), dont ils ont compare\u0301 l\u2019e\u0301volution de la taille des cornes sur le museau. Il en ressort inde\u0301niablement que celles-ci ont re\u0301tre\u0301ci durant ces dernie\u0300res anne\u0301es.<\/p>\n

Un triste phe\u0301nome\u0300ne provoque\u0301<\/p>\n

Selon les chercheurs, ce triste phe\u0301nome\u0300ne est provoque\u0301 par le braconnage. En effet, les chasseurs tuent les animaux avec les cornes les plus grandes au de\u0301triment des autres, puisque la corne du rhinoce\u0301ros est dit-on tre\u0300s pre\u0301cieux dans certaines me\u0301decines populaires.<\/p>\n

Ce \u201cfavoritisme\u201d a permis la survie des rhinoce\u0301ros a\u0300petites cornes, et ceux-la\u0300 transmettent ces caracte\u0301ristiques physiques a\u0300 leur proge\u0301niture.<\/p>\n

Les cornes des rhinoce\u0301ros n\u2019ont donc pas re\u0301tre\u0301ci consciemment, mais c\u2019est le fait d\u2019une se\u0301lection ge\u0301ne\u0301tique indirecte.<\/p>\n

Mauvaise nouvelle pour la nature<\/p>\n

L\u2019e\u0301tude donne une autre information capitale: seules les cornes ont re\u0301tre\u0301ci, les autres parties du corps n\u2019ont pas e\u0301volue\u0301. Mauvaise nouvelle, car les cornes leurs sont tre\u0300s utiles pour se nourrir et se de\u0301fendre contre les pre\u0301dateurs et me\u0302me de trouver une partenaire pour se reproduire.<\/p>\n

De nos jours, les rhinoce\u0301ros restent menace\u0301s par la chasse bien qu\u2019elle soit interdite. Certaines espe\u0300ces de rhinoce\u0301ros vivant en Afrique et en Asie sont en voie de disparition.<\/p>\n
