Denisovan. denisovan hiddawadayaasha

dabeecadda aadanaha, asalka ah ee nin - taasi waxa weeye waxa farxad gelineysa dadka tan iyo wakhtiyadii hore. Waxaa jira versions iyo aragtiyo badan. Seynisyahanno ka qabashada cilmi, isku dayaya in ay ka heli jawaabaha su'aalaha oo dhan. Ka dib markii reading article ah, waxaad ku baran doontaa dacawo kale dadka bakhtiyeen qadiimiga ah.

Denisovan ama denisovets filayo jiray Soloneshensky Degmada Altai Krai dhow Cave Denisova. Caddeynta for this laga helay qaybo kala duduwan oo ku layers kala duwan ee godka.

Waqtigan xaadirka ah, waxaa laga helay kaliya shan xabbadood, ogolaanaysaa hadal ku saabsan denisovan. Si kastaba ha ahaatee, tareenka, kuwaas oo ilaa hadda kuma filna in la soo celiyo muuqaalkiisa gebi ahaanba. Si kastaba ha ahaatee, jajabkii helay ku filan oo ay ku doodayaan in hadhaagii ninkii ka duwan hadhaagii faaftay Sapiens, iyo sidoo kale hadhaagii Neanderthal ah.

Denisova godkii

godkii, taasina waa waanada qaddiimiga ah kuwa ugu caansan, kuwaas oo ku faani karo ee Altai. Denisovan halkan ku noolaa, 250 kiiloomitir u jirta magaalada Biisk. godka waa wax weyn, aagga of 270 m².

Waxay ku taalaa meel u dhow degsiimooyinka iska leh nooc ka mid siman, taas oo soo jiidataa tiro badan oo dalxiisayaal ah. Si kastaba ha ahaatee, halkan aad waxaa jira qadiimiga ah, shaqo adag oo weli keentay in natiijo.

Sida laga soo xigtay natiijooyinka waxbarashada ee layers hoose ee godka, kuwaas oo da'da ku saabsan yahay 120 kun oo sano, qalab dhagax oo isku sharraxdid la helay, sidoo kale raad nin qadiimiga ah, kan uu magacaabay Denisovskoe.

Jajabkii denisovan hadhaagii

Inta lagu jiro jiritaanka gobolka Soviet saddex gowsaha laga helay size ka sii badan intii ilkaha aadanaha waa macquul. Sida laga soo xigtay baadhitaanka, waxay lahaayeen qof lab ah da 'yar. Sidoo kale waxaa laga helay phalanx goosin ka mid ah, falanqaynta ee element ah waa la fuliyay ilaa haatan.

lafta farta ilmaha phalanx - At muddo ka dib, ayaa element kale waxaa laga helay sanadkii 2008.

denisovan hiddawadayaasha

Jajabkii helay denisovan phalanx ah la bartay kooxda reer Institute for Leipzig saynisyahano Evolutionary Anthropology. Baadhitaanka ayaa muujiyay, in DNA mitochondrial denisovan ka DNA mitochondrial of sapiens faaftay at 385 nucleotide kala duwan. Waa in la ogaadaa in hiddawadayaasha Neanderthal ka duwan tahay hiddawadayaasha of faaftay Sapiens 202 nucleotides.

Denisovan dheeraad ah si dhow ula xiriira Neanderthals ka badan in qof macquul ah. Sidoo kale xusid mudan waa in hiddo ay ayaa laga helay Melanesians ah, iyo in oo noo ogolaadaa in ay ku hadlaan oo ku saabsan isgoyska mass ka mid ah dadka waqti Melanesians ee ka soo Africa oo u guuray ee koonfur-bari.

Faracoodii denisovan

Sida laga soo xigtay waxbarashada, denisovan soocay sida dacawo ah oo qiyaastii 400-800 oo kun oo sano ka hor. Maanta, daraasadda laga helay jajabkii Denisova Cave kuu ogolaanaya in aad si aad u hesho hiddo ay quruumo badan oo casri ah. Tusaale ahaan, inta badan oo ka mid ah xubno ka mid ah laga helay deggan dalalka koonfur bari Asia iyo koonfurta Shiinaha, inkastoo xaqiiqda ah in ay raad laga helay oo ka mid ah dadkii hore ee Siberia.

Waxaa sidoo kale lagu ogaaday in ay dacawo la odhan jiray dadka bakhtiyeen, iyo sidoo kale ninka Neanderthal, gudubtay hiddo dadka Yurub ee habka difaaca jirka. Sababta oo ah raadinta waxaa sidoo kale wuxuu ahaa awoodaan si ay u sameeyaan model computer muujinaya Jidka socdaalka ee noocyada kala duwan ee awoowayaasha dadka iyo meelo ka mid ah kulamada ay la denisovtsami ah.

Seynisyahanno ku Sweden ayaa sheegaya in si aad u hesho raad denisovan suurto gal by barbar natiijada DNA la DNA ee aadanuhu casriga ah.

Ka dib markii la barbardhigo ah macluumaadka la helay sida denisovtsa la mid ah nin casri ah, oo ku saabsan kulan laga helay Neanderthal iyo denisovtsa. Sidoo kale, waxaan ogaanay in hiddo-denisovan ku jira ee noocyo ka mid ah dadka ka tirsan dadka Oceanic iyo non-African.

Shaqo Dugsiga Caafimaadka Harvard

Sida laga soo xigtay cilmi Dugsiga Caafimaadka Harvard, denisovtsy badan socday ka aadanuhu casriga badan Neandertals ah, inkasta oo markii hore ay ahaayeen, marka adeer. Waxaa loo maleynayay in Neanderthals iyo denisovtsy si siman uga duwan sapiens faaftay. Si kastaba ha ahaatee, saynisyahan Harvard ee David Reich ahaa awoodaan in ay Diidi.

Si kastaba ha ahaatee, saynisyahan ayaa sheegay in farqiga this lagu macnayn karaa by xaqiiqada ah in denisovtsy interbred leh noocyada kala duwan ee dadkii hore.

barta of view of saynisyahan Jarmalka Iogannesa Krauze

geneticist Jarmal Johannes Krause oo ka tirsan Jaamacadda Tübingen arko in in ay iska indha jajabkii ka helay kiis kasta wax aan macquul aheyn. Wada jir ah ula saaxiibadiisa cilmiga barashada denisovan hiddo-waayo joogitaanka raad interbreeding. Xaqiiqada ah in denisovtsa ilkaha helay waa mid aad u weyn oo loogu talagalay noocan ah nin qadiimiga ah. Waxa ay u muuqataa in ay awoowe toos ahayd nooc ka heer hoose ah.

Sida laga soo xigtay borofisar ka, si ay u sharxaan qariibnimo ah ee ilkaha iyo sidoo kale laga yaabaa in version ah in denisovtsy interbred la versions shinka dadka. Waxaa intaa dheer, sida uu sheegay borofisarku, u badan tahay, waxaa la horey u yaqaan noocyada, sida badan oo iyaga ka bartay heer hidaha.

Maxaa saynisyahano odhan London?

cilmibaadhe London Chris Stringer ee Dabiiciga ah History Museum ee UK uu aaminsan yahay in nin Heidelberg, gelida Europe iyo Western Asia, inuu hanan karo denisovan, taas oo keentay in isgoyska mass ah. Waxaa sidoo kale waa fursad aad u fiican oo laga yaabaa nin erectus, maadaama ay ahayd wax caadi ah in meelo badan, oo la kulmi karaa denisovtsami.

Dabcan, aad xalin karo, kuwaas oo khilaaf by yahay falanqaynta DNA caadiga ah ee noocyada oo dhan, laakiin tani suurtogal ma aha, maxaa yeelay, waxay si fudud ma noolaadaan. Inta badan Homininae degay deegaanno kulul, laakiin sababta oo ah hadhaagii ay hiddawadayaasha la ma wada ilaaliyo, ka duwan denisovtsev Neandertal kaas oo laga helay inta badan ee xaaladaha adag iyo qabow.

Doorka cross-taranta ee dabeecadda aadanaha

Sida maanta, waxaan ognahay wax badan oo ka mid ah noocyada iyo dacawo ah dadkii hore, kuwaas oo awowayaashayo. Waa in aynaan diidi xaqiiqada ah in ka dib markii awoowayaasha aadanaha guurtay of Africa, ay aadeen kala duwan ee noocyada kale. Waxay u badan tahay in qaar ka mid ah genomes kale oo xiiso leh lagu rakibi doonaa mustaqbalka.

Xilligan la joogo, waxaan ognahay in ay jirto isgoyska a mass joogto ah, oo ay ku jiraan hominin ah weli la garanayn. Like saynisyahano badan odhan noocyada kale ee xiisaha kacday 700,000 oo sano ka hor.

Iyada oo ku saleysan waxbarashada, waxaannu ku tirinnaa karaa in waqti qaar ka mid ah inta lagu guda jiro horumar Aadanaha u qaybsan yahay khadadka dhowr, mid ka mid ah taas oo markii danbe keentay in denisovan, iyo kuwa kale ee ka soo awowayaashiin more hore ee sapiens faaftay oo nin Neanderthal yimid. Sidoo kale, saynisyahano ogaaday in Neanderthals denisovtsy oo kale faaftay Sapiens markii qaar ka mid ah deganaa Altai iyo gudbeen kasta oo kale. Intaa waxaa dheer, isgoyska dhacay la noocyada kale ee la kulmay denisovtsam waqtiyo kala duwan iyo in dhulal kala duwan.

Waa wax laga xumaado ah in ma noolaan DNA ee noocyada kale ee dadkii hore, haddii kale xiriir la si cad u ogan karo. Si kastaba ha ahaatee, sayniska casriga ah ee nin weli ma istaagi, iyo laga yaabee ugu dhakhsaha badan waxaan ku baran doonaa wax cusub oo ku saabsan asal ahaan naga.
