Le tsekamelo ea ho kulisoa? Mohlomong molato oa liphatsa tsa lefutso tsa hao Neanderthal

Haeba u qoba lipalesa tse hlaha, ditholwana dilamunu, chokolete kapa linate ka lebaka la ho kulisa, ka nako eo beha molato oa hao Neanderthal baholo-holo ba, kapa ho ena, liphatsa tsa lefutso tsa bona.

Moo re nang le Neanderthal liphatsa tsa lefutso?

E o tsejoa hore Neanderthals le Cro-Magnons denisovtsy (baholo-holo ba batho ba mehleng ea kajeno) - tse mefuta e meraro e fapaneng. Joale, kajeno, batho ba bang ba bonahalang eka ba ka Neanderthal kapa Denisovskoe liphatsa tsa lefutso?

The phelisana la dimela tsena fapaneng e ne e-ba ea nakoana haholo, empa a sa ntse ho lekaneng ho e phela hammoho libakeng se tšoanang. Ho phaella tabeng ea ho ba le lintoa le likhohlano tsa botho ha manyalo a se tsoakaneng, 'me bana ba hlahile ho bona e ne e le poone e nyalisitsoeng - bajari ba liphatsa tsa lefutso e le' ngoe, 'me ba bang. Ka mor'a ho fihla ha Cro-Magnon le Neanderthal Denisovskoe batho o tla tloha o nyamela le sefahleho tsa lefatše, a le siela monna morao-rao ho 4% ea liphatsa tsa lefutso tsa bona.

kamano ea seo ba se futsitseng liphatsa tsa lefutso bakeng sa kulisoa?

Allergy - ba ikutloa ka tsela ya boitshireletso ba mmele ho ho susumetsa ba bang. Haeba o na le kulisoa, ha e bolele hore u na le sesole sa 'mele fokolang, ho ena le hoo. Sena Peresente nyenyane ea liphatsa tsa lefutso, u li futsitseng ho ea moholo-holo oa Neanderthal, na hao tsamaiso boitshireletso ke falimehile haholo le lebelo ho pefo. Ka hona, ho tsoela likokoana-hloko, e seng feela ho le tšoaetso ea, empa e boetse e le bothata ba joaloka peō le phagocyte fluff.

Mong le e mong motho ho ba setho sa peiso Caucasian, futsitseng ho 1 ho ea ho 6% ea liphatsa tsa lefutso ea Neanderthal balimo. Ke hobane'ng ha ho sa e alejiki itsoara joang ho hang? Anthropologists le geneticists li bontšitse hore Neanderthal monna likarabo boitshireletso ba 'nile ba ba le molemo haholo ho feta ho Cro-Magnons. Neanderthal liphatsa tsa lefutso li futsitseng batho kajeno, phello bohlokoa ka ho fetisisa ka receptors Toll-joaloka, e laola tsamaiso ea tlhaho ea boitshireletso le ea 'mele ea ka karabelo lisele ho susumetsa ba bang. Ka lebaka leo, a phahameng ea Peresente la ho futsa ho liphatsa tsa lefutso, e khōlō le monyetla oa ho kulisa.

Lipatlisiso tsa kajeno liphatsa tsa lefutso

Ka Khatiso ea morao tjena ea Journal American tsa Botho liphatsa tsa lefutso, ba babeli ba le ikemetseng le sa amaneng ho lithuto tsa e mong le e tse ling ba tlile ho etsa qeto ea e tšoanang: ho Neanderthal le Denisovskoe liphatsa tsa lefutso ho fetisisa ka matla a bonahatsa ka boitshireletso ba mmele.

Dr. Michael Dannemann e se e ho ithuta lefa likarolo foqohe tsa DNA ea motho. O ile a tla ho etsa qeto ea hore receptors Toll-joaloka ba ka ho fetisisa angoa ke allele tsa liphatsa tsa lefutso tsa Neanderthals. Ho ea ka ho etsa lipatlisiso tsa hae, 11 ho ea ho 51% ya batho ba e matleng a hae ho moloko oa African, na allele bonyane e mong oa Neanderthal. The boholo ba karolo e ka fapana ho itšetlehile ka moloko oa batho.

A ho ithuta bobeli khanna Dr. Luis Quintana-Mursi.
