Mbiri ya Chitukuko cha Chiphunzitso cha Chisinthiko ndi Charles Darwin
Pendauluan
M'mbiri ya sayansi, ziphunzitso zochepa chabe zakhala ndi mphamvu yaikulu komanso yodabwitsa monga chiphunzitso cha Charles Darwin cha chisinthiko. Chiphunzitsochi chinasintha momwe timamvetsetsera chiyambi cha moyo ndi malo a anthu m'chilengedwe chonse. Chiphunzitsochi chisanapangidwe, lingaliro lalikulu linali lakuti mitundu yonse ya zamoyo inalengedwa yokhazikika komanso yosasinthika ndi mphamvu yaumulungu. Komabe, mwa kuyang'anitsitsa mosamala ndi kuganiza mozama, Darwin adapanga chiphunzitso chomwe chimafotokoza momwe kusintha kwa zamoyo kumachitikira kudzera mu kusankha kwachilengedwe. Nkhaniyi ifufuza mbiri ya chitukuko cha chiphunzitso cha Charles Darwin cha chisinthiko ndi momwe chimakhudzira sayansi ndi anthu.
Mbiri ya Charles Darwin
Charles Robert Darwin anabadwa pa February 12, 1809, ku Shrewsbury, Shropshire, England. Kuyambira ali mwana, Darwin anasonyeza chidwi chachikulu pa chilengedwe. Atalowa mu yunivesite ya Edinburgh kukaphunzira zamankhwala, chidwi chake chinasanduka mbiri yachilengedwe atapeza kuti sangathe kupirira njira zonyansa zachipatala za nthawiyo. Kenako Darwin anasamukira ku yunivesite ya Cambridge, komwe adapeza malangizo auzimu ndi asayansi kuchokera kwa Pulofesa Henslow, yemwe anali ndi mphamvu yaikulu pa ntchito yake.
Ulendo wa HMS Beagle
Chimodzi mwa zochitika zazikulu pa moyo wa Darwin chomwe chinakhazikitsa maziko a chitukuko cha ziphunzitso zake chinali ulendo wake wopita ku HMS Beagle pakati pa mapulaneti. Ulendowu, womwe unatenga kuyambira pa Disembala 27, 1831, mpaka Okutobala 2, 1836, unathandiza Darwin kufufuza mitundu yosiyanasiyana ya biomes ndi geological formations, kuyambira ku South America ndi Zilumba za Galápagos mpaka ku Australia ndi mapiri a Andes. Pa ulendowu, Darwin anasonkhanitsa zitsanzo zambiri za zomera, nyama, ndi mafupa, ndipo anafufuza mosamala za kusiyana kwa moyo m'malo osiyanasiyana.
Chikoka cha Zilumba za Galápagos
Zomwe Darwin anaona pa Zilumba za Galápagos zinali zina mwa zofunika kwambiri pakukula kwa chiphunzitso chake. Darwin anapeza kuti mbalame za m’zilumbazi zinkasonyeza kusiyana kwa mawonekedwe a milomo ndi kukula komwe kunkaoneka kuti kukugwirizana ndi mtundu wa chakudya chomwe chimapezeka pachilumba chilichonse. Izi zinapereka lingaliro kwa Darwin kuti mitundu ya zamoyo sinakhazikike koma ikhoza kusintha malinga ndi momwe zinthu zilili. Lingaliro limeneli la kusinthasintha ndi kusintha pambuyo pake linakhala maziko a chiphunzitso cha Darwin cha chisinthiko.
Chiphunzitso cha Chisinthiko ndi Kusankha Kwachilengedwe
Mu 1838, Darwin anawerenga ntchito ya Thomas Malthus yokhudza kuchuluka kwa anthu ndi zinthu, yomwe inafotokoza momwe kuchuluka kwa anthu kumakulira mofulumira kuposa momwe chakudya chimakhalira. Malingaliro a Malthus adalimbikitsa Darwin kunena kuti zamoyo zimavutikanso kukhala ndi moyo m'chilengedwe. Darwin adapanga lingaliro la kusankha zachilengedwe, komwe anthu omwe ali ndi mitundu yosiyanasiyana yoti apulumuke m'malo awo amakhala ndi mwayi waukulu wobereka ndikupereka makhalidwe amenewo kwa ana awo.
Darwin asanafalitse chiphunzitso chake kwambiri, anakambirana ndi anzake komanso anafunsana nawo. Komabe, sanazengereze kuchifalitsa, poopa kuti chingatsutsidwe ndi magulu amphamvu asayansi ndi achipembedzo panthawiyo.
Buku lakuti “Pa Chiyambi cha Mitundu”
Chidwi cha Darwin chofalitsa chiphunzitso chake chinalimbikitsidwa ndi wasayansi wachinyamata dzina lake Alfred Russel Wallace, yemwe adafika pamlingo wofanana pa nkhani ya chisinthiko mwa kusankha zachilengedwe. Mu 1858, Wallace adatumiza Darwin pepala lofuna maganizo ake pa malingaliro ake. Pofuna kulemekeza kuyamikira kwa Wallace ndi kukhazikitsa mfundo zofunika, Darwin adamaliza mwachangu zolemba zake ndikufalitsa "On the Origin of Species by Means of Natural Selection" pa Novembala 24, 1859.
Bukuli nthawi yomweyo linayambitsa chisokonezo, ndipo linayamikiridwa komanso kutsutsidwa ndi anthu osiyanasiyana. Lingaliro lake lachilengedwe la chiyambi cha zamoyo linatsutsa mawu ofala a kulengedwa kwa zamoyo ndipo linasuntha sayansi kupita ku njira yatsopano kutengera umboni wodalirika.
Kulandira ndi Kukangana
Chiphunzitso cha Darwin chinatsutsidwa kwambiri ndipo chinatsutsidwanso ndi asayansi ena ndi anthu ena achipembedzo. Ambiri anakayikira ngati umboni wa Darwin ndi woona, pomwe ena ankaona kuti chiphunzitso chakecho chinali chonyoza ziphunzitso zachipembedzo. Komabe, asayansi ambiri anachita chidwi ndi chiphunzitsochi ndipo anayamba kufunafuna umboni wina wochirikiza.
Kwa zaka zambiri, magawo osiyanasiyana a sayansi, kuyambira majini mpaka paleontology, apereka umboni wokhutiritsa chiphunzitso cha chisinthiko mwa kusankha kwachilengedwe. Mwachitsanzo, zomwe Gregor Mendel adapeza mu majini, zinapereka maziko a mamolekyulu a cholowa cha makhalidwe omwe Darwin sanathe kufotokoza kale.
Chitukuko cha Pambuyo pa Darwin
Pambuyo pa imfa ya Darwin pa Epulo 19, 1882, chiphunzitso cha chisinthiko chinapitirira kukula ndipo chinalimbikitsidwa ndi zinthu zosiyanasiyana zomwe asayansi anapeza. Kumayambiriro kwa zaka za m'ma 20, gawo la majini amakono, lomwe linayambitsidwa ndi asayansi monga Thomas Hunt Morgan ndi kujambula mapu a DNA ndi James Watson ndi Francis Crick mu 1953, linalimbitsa maziko asayansi a chiphunzitso cha chisinthiko. Chisinthiko tsopano chinkaonedwa osati kudzera mu kusintha kwa thupi kapena mawonekedwe, komanso pamlingo wa mamolekyulu ndi majini.
Zotsatira za Anthu ndi Filosofi
Chiphunzitso cha Darwin cha chisinthiko chakhala ndi mphamvu yaikulu pa filosofi, chikhalidwe cha anthu, ndi zaumulungu. Chinatsutsa lingaliro la chikhalidwe cha anthu lomwe linkalamulira kumvetsetsa kwathu za moyo ndi udindo wa anthu m'chilengedwe chonse. Mu filosofi, chiphunzitso cha chisinthiko chalimbikitsa chilengedwe ndi kukonda zinthu zakuthupi, ndikugogomezera kuti moyo ndi kapangidwe ka zamoyo zitha kufotokozedwa popanda kugwiritsa ntchito zinthu kapena mphamvu zauzimu.
Komabe, chiphunzitsochi chagwiritsidwanso ntchito molakwika m'malingaliro oipa monga eugenics ndi social Darwinism, komwe mfundo za kusankha zachilengedwe zimagwiritsidwa ntchito molakwika m'mikhalidwe ya anthu ndi ndale, nthawi zambiri pofuna kulungamitsa tsankho ndi mfundo zotsutsana.
Mapeto
Chiphunzitso cha Charles Darwin cha chisinthiko chinali chitukuko chachikulu pakumvetsetsa kwathu za moyo. Sichinangosintha zamoyo zokha komanso chinakhudza madera ena ambiri a chidziwitso cha anthu. Mwa kupereka njira yamphamvu yasayansi yofotokozera chiyambi ndi chitukuko cha zamoyo, Darwin anapereka dongosolo lolemera komanso losinthasintha lomwe lalimbikitsa kafukufuku watsopano ndi zinthu zatsopano kwa zaka zoposa zana. Cholowa chake chikupitirirabe, pamene tikupitiriza kufufuza zovuta za moyo ndi njira zachilengedwe zomwe zimapangitsa moyo padziko lapansi.
