- Nyob rau xyoo 1828 tus kws tshuaj German Friedrich Wohler tau tsim cov urea artificially siv Silver isocyanate & ammonium chloride. - Qhov no yog thawj zaug uas cov organic tebchaw tau muab cov khoom tsim tawm. - Nws tau pab ua qhov cuav ntawm txoj kev xav ntawm vitalism vitalism 20th century
Hans Driesch (1867–1941) txhais nws cov kev sim ua qhia tias lub neej tsis khiav los ntawm physicochemical txoj cai. Nws qhov kev sib cav tseem ceeb yog tias thaum ib tus txiav ib lub embryo tom qab nws thawj zaug los yog ob, txhua feem loj hlob mus rau ib tug neeg laus tiav. https://en.wikipedia.org › wiki › Vitalism

tab sis tsis tau lees paub kiag li.
Vitalist txoj kev xav tau dag li cas?
Txoj kev xav yog tsis lees paub los ntawm Friedrich Wohler, uas tau pom tias cov cua sov nyiaj cyanate (ib qho tshuaj inorganic) nrog ammonium chloride (lwm inorganic compound) tsim urea, tsis muaj kev pab los ntawm ib tug inorganic compound. Cov kab mob nyob los yog ib feem ntawm cov kab mob muaj sia.
Lub tswv yim twg Wohler tau dag?
Friedrich Wöhler yog ib tug kws tshuaj German nto moo uas paub zoo tshaj plaws ntawm kev sib txuas ntawm urea, ib qho organic compound, los ntawm ammonium cyanate, ib qho ntsev inorganic, yog li disproving txoj kev xav ntawm 'vitalism', cov tshuaj organic tsuas yog tsim los ntawm cov khoom muaj sia xwb.
Wohler tau ua pov thawj li cas qhov tseem ceeb ntawm lub zog txoj kev xav?
Qhov kev xav no tau lees paub thaum Friedrich Wohler ua urea (ib qho organic compound) los ntawm ammonia (ib qho inorganic.compound).
Txoj kev xav ntawm qhov tseem ceeb yog dab tsi thiab nws tau dag li cas?
Vitalism yog cov lus qhuab qhia uas txiav txim siab tias cov organic molecules tsuas yog tsim los ntawm cov kab ke nyob. Nws tau ntseeg tias cov tsiaj muaj sia muaj qee yam "lub zog tseem ceeb" uas xav tau los ua cov organic molecules. Yog li cov organic tebchaw tau xav tias muaj cov khoom tsis yog lub cev uas tsis muaj los ntawm cov khoom tsis muaj roj molecules.
