Ijuba elithwalayo selisebenze iminyaka eyi-15-20. Inyoni eqeqeshwe kahle ingandiza ifike ku-1000 km. Uhlamvu luvame ukufakwa ku-capsule yepulasitiki futhi ixhunywe emlenzeni wejuba. Kuyinto evamile ukuthumela izinyoni ezimbili ngesikhathi esisodwa ngemilayezo efanayo, ngenxa yengozi yokuhlaselwa kwezinyoni ezidla inyama, ikakhulukazi oklebe.
Izinganekwane zithi ngosizo lwamajuba othwala, abathandi bashintshana ngamanothi. Icala lokuqala eliqoshiwe lejuba lihambisa incwadi lalingo-1146 AD. UCaliph wase-Baghdad (e-Iraq) uSultan Nuruddin wasebenzisa i-pigeon mail ukuze alethe imiyalezo embusweni wakhe.
Phakathi neMpi Yezwe I, amajuba eButho LaseMelika asindisa ibutho ekuthunjweni amaJalimane. E-India, ababusi u-Chandragupta Maurya (321-297 BC) no-Ashoka basebenzisa i-pigeon mail.
Kodwa, ekugcineni, iposi, i-telegraph kanye ne-intanethi yavela emhlabeni. Naphezu kweqiniso lokuthi iplanethi izungezwe iziphuphutheki, i-pigeon mail ayizange ishone esikhathini esidlule. Amaphoyisa esifunda sase-Orissa e-India asasebenzisa izinyoni ezihlakaniphile ngezinjongo zawo. Banamajuba angu-40 aqede izifundo ezintathu zokuqeqesha: static, mobile kanye ne-boomerang.
Izinyoni zesigaba esimile ziyalwa ukuba zindiza ziye ezindaweni ezikude ukuze zixhumane nendlunkulu. Amajuba esigaba seselula enza imisebenzi eyinkimbinkimbi ehlukahlukene. I-boomerang iwumsebenzi wejuba ukuletha incwadi bese ibuya nempendulo.
Amajuba athwalayo ayinkonzo ebiza kakhulu. Zidinga ukudla okunomsoco obizayo, zidinga amafutha esibindi sikashaka ahlanganiswe ne-potash encibilikiswe emanzini. Ngaphezu kwalokho, bafuna ubukhulu bekheji labo.
Amajuba asindise abantu ngokuphindaphindiwe ngezikhathi eziphuthumayo nezinhlekelele zemvelo. Ngesikhathi sokugubha iminyaka eyikhulu yenkonzo yeposi yaseNdiya ngo-1954, amaphoyisa ase-Orissa abonisa ikhono lezilwane ezifuywayo. Amajuba ahambise umyalezo wokugcotshwa kukaMengameli waseNdiya kuNdunankulu.
