Takooro habab bayoolaji. Noocyada takooro tusaalooyin hababka

Qofna ma diidi doonaa in xaqiiqada dhabta ah ee nagu wareegsan waa habboonaanta iyo kaamil ah. Waxba ma ahan wixii ama kuwa aaminsan in dadka isaga ka ag dhow laakiin wuxuu arko ma aha oo kaliya quruxda iyo kala duwanaanta, laakiin sidoo kale si qani ah oo ma jirto meel fowdo. Gaar ahaan si cad u muujiyey fiican oo nadiif ah dunida of xayawaankii. All daciif ah, fool xun, oo aan awood u leh inay soo saari caafimaad qaba oo hanaqaad hankoodii saamaynta horumar ah ee arrimood, ugu horreeya oo dhan, by doorashada dabiiciga ah. Ma aha doorka ugu danbeysay waxaa ciyaaray iyo geedi socodka noolaha sida go'doomin taranka.

Tani waxay, sidoo kale noocyo kale oo habab ilaaliya, ilaalada balliga hiddo geedka, xayawaanka iyo insaanka ah, waxaanu ka fiirsan in warqad this.

kala iibsiga ee sifooyin kala dhaxlo - hantida ugu weyn ee arrinta ku nool

Dhalmada - habka ugu muhiimsan ee wixii jiritaanka aad u of arrin nolosha suurto gal on Earth. Marka laga heerka ay ururka, laga bilaabo fudud iyo dhamaanayey nuujiya, unugyada labka iyo dheddiga (dhirta - pollination), taasoo keentay in soo bixitaanka of a-gal, farcankaaga bacrin ah, waxay dhacdaa keliya oo u dhexeeya shakhsiyaad ka tirsan dadweynaha oo ka mid ah noocyada la mid ah. Waa wax iska cad in ay jiraan habab qalabada dabiiciga ah gacanta pollination ama ku taalba.

Dabcan, ma meesha ka saaray suurtagalnimada xaaladood oo interbreeding. Waxay dhacaan labada dabiici ah iyo kiimikaysan qabtay - nin, laakiin had iyo jeer ku siin kor u qaada Farac kasta oo meelmar ah oo yaraada ama Beelaha oo Nadiif ah. Waxaa ugu Filan in yeeran baqlo dhalays - farcankaaga helay by gudbaya dameer iyo geenyo ah. Sida laga arki karo, waxaa jira ciidamo gaar ah oo la oran karo waa sida noocyada qaar ka mid ah la takooro habab. Waxaan iyaga u qeexaan in faahfaahin dheeraad ah.

Qoondaynta oo ah hawlgaladii ugu taasoo keentay in xasiloonida ee pool hiddo-ee dadweynaha

In aragtida evolutionary, taas oo waa wax soo saarka shaqada wadajir sayniska ee saynisyahano sida Charles Darwin, AN Severtsev, G. Spencer, tixgelin soo socda, kuwaas oo ifafaale baahsan in ay gacan xasiloonida ee jiritaanka noocyada: go'doomin juquraafi, dhawrista iyo taranka. Biology Section - genetics dadka, waa mashquul barashada isbedelada ka dhacaya pool hiddo bulshooyinka ee noolaha ah. Waxay yihiin natiijada arrimood sida hirarka nolosha iyo miyigii hidaha.

laan soo sheegnay ee biology abuurayaa doorka arrimaha difaaca, loogu talagalay ilaalinta karyotypes qiimaynta shakhsiyaadka ku nool iyo ka hortagga, iskutallaabtiisana ha ka dhexeeya dadweynaha. Next, waxaan ka heli doonaa nooca takooro farsamo loo yaqaan deegaanka, iyo waxa ay muhiimadda in dayactirka ka kooban joogta ah hiddo-ee dadka ah.

Doorka xaaladaha deegaanka ee ilaalinta ee pool hiddo bulshooyinka ee noolaha ah

Sidaas darteed of phylogeny - horumarka taariikhiga ah ee noocyada ah, shakhsiyaadka ay, u sameeyaan nool dadka gudaha xuduudaha dhul gaar ah, loo yaqaan hoygii. Dhirta iyo xayawaanka la macaamilaan arrimaha deegaanka, iyo sidoo kale bulshooyinka ee noocyada kale ee ku nool dhulka, la, a mashquulin Misbaax dhawrista qaarkood. Si loo yareeyo xoogga tartan u dhexeeya dadka ka mid ah mid ah noocyada, waxaa jira habab go'doomin gaar ah si loo hubiyo in, tusaale ahaan, farqiga u ah shuruudaha labada kooxoodba ku saabsan nooca cuntada. Sidaas, iyo jiriqsiga iyo weevil digir abuuraa laba bulshooyinka cayayaanka, mid cuna miraha digir, kan kale - digir ah.

Muddada taranka, sababta oo ah dalagyada calafka koraan ee jiidaha kala duwan, laba dadka of noolaha aan is gudbaan.

Terms of taranka iyo muhiimadda ay leedahay in la hubiyo xasiloonida ee dadka hidde

Saameeye oo si weyn u wiiqaysaa ama xataa gebi ahaanba lagu cabudhinayo pollination ama shahwaddiisu ka dhexeeya noolaha ah qaybaha nidaamsan ka mid ah hababka la takooro in la xakameeyo waqtiga dhalmo ah oo ay shakhsiyaad. Tusaale ahaan, ubax cawska oo berrin bannaan, kaas oo ku koraa estuaries, correlatively xiran joojinta ku meel gaar ah daadka guga. Geedaha in si toos ah ku nool xeebta iyo in muddo daadka waa muddo dheer biyo ka yar, ubaxyada dambayn dadka sarkhaansan yihiin daad-gaaban, ama daadad ma ay ahayn. Sababo cad panmixia (cross-pollination) u dhexeeya dhirta ku nool qaybaha kala duwan ee seeraha ku, waxaa la waayay, tan iyo koriinkedu of manka ay dhacaan waqtiyo kala duwan. Sidaas darteed, images of dadka dhowr ka mid ah cawska oo berrin bannaan, xilliyada kala duwan taranta.

Doorka evolutionary of ningax

genetics Population ayaa aasaasay xaqiiqda ah in awood la'aanta iswaydaarsigu hiddo u dhexeeya noolaha ee jinsiyadaha kala duwan ama bulshada u keenaysaa in xaqiiqda ah in noocyo ka mid ah shaqsiyaadka ka dhacaan noocyada gebi ahaanba kala duwan oo Isbedelo, oo badala inta jeer ee dhacdo sida alleles xukuma iyo recessive. Tani waxay keenaysaa in xaqiiqda ah in barkadaha hiddo dadka dheeraad ah oo kala duwan oo midba midka kale ka. Meelaan Tani waxay khuseeyaan doonaa, ugu horreeya oo dhan, noocyo ka mid ah qabsashada deegaanka abiotic. On maxay ku xiran tahay?

saamaynta Comprehensive noocyada kala duwan ee ningax

Waxay ku salaysan tahay hababka la takooro deegaanka iyo taranka isku xiran. Biology, gaar ahaan ay qaybta - aragtida ah ee horumar, tilmaamaysaa raadka ay ku leeyihiin muujinta habkan caalami ah, kala ah, ie sifooyinka kala iyo sifooyinka noolaha. Waxaa been wadnaha ee microevolution - geedi socodka taasoo keentay in formation of hore ee noocyada sub, ka dibna, iyo noocyada cusub ee dabiiciga ah.

Sidee go'doomin juqraafi

In cilmi barasho dhir, iyo cilmi barasho xayawaan, saynisyahano yihiin bixinta si ay arrimo in ku dhawaad yareeyo eber jaaniska of isgoyska free u dhexeeya shakhsiyaad ka mid ah noocyada la mid ah dareenka halis ah. Waxa uu helay magaca go'doomin juqraafi. Waxaa soo baxay in isbedel fiiqan in dhul la daruuri Ulasocto ah ee hortaagan in dawadda kala duwan asaasiga ah ka mid ah noolaha.

Waxay la xidhiidhaan, gaar ahaan, waqtiga waqtiga koriinkedu gamete shahwaddiisu ama pollination. arrimood oo dhan waa laydinku dari karaa in mid ka mid dheer - go'doomin taranka. Waa maxay cawaaqibta ka imanaysa jiritaanka dadka ah waxay u horseeddaa?

calaamadaha kala

Qubarada ayaa lagu ogaaday in dadka of noolaha in ay leeyihiin genomes la mid ah hore, muddo noqday a sifooyin kala duwan oo waaweyn sababta oo ah ka lumay sida saad cunto hal, iyo suurtagalnimada of isgoyska free. caqabadaha jirka gudbi karin qaab jajab ee qaaradood ah, kor u safafka buurta, oo webiyaasha daadan bulshada go'doon ah oo ay shakhsiyaad midba midka kale ka. Waa sidan yeesho duur-joogta. Tusaalooyinka oran siiyey muujiyo go'doomin juquraafi sida hab muhiim ah oo speciation. Sayidka, kooxda nuujiya marsupial Australia ka dib markii ay kala qaaradda hore ee Gondwana, waxay leeyihiin kala duwan jidh iyo nafeedba u weyn ka noocyada Yurub oo casri ah soo baxay ka dib markii glaciation Weyn.

Charles Darwin oo ku saabsan hababka of speciation

abuuraha dunida-caan ah ee aragtida ah ee doorashada dabiiciga ah, naturalist ah Ingiriisi Charles Darwin, ayaa loo aqoonsaday xoogagga ah ee horumar, taasoo keentay in soo bixitaanka of fasallo cusub, amarada iyo qoysaskooda ee noolaha. Sidoo kale in saynisyahan shuqullada tilmaamay habab juquraafi iyo dhawrista go'doomin. Tusaalooyinka daliilka kuwan, oo uu ka indhaynta sameeyey intii uu safar caan adduunka oo dhan soo urursaday. Darwin arkay iyo sketched noocyada kala duwan ee finches ku nool Islands Galapagos ah. Shimbiraha ahaayeen kala duwan riwaayado in qaab reer size dhuuban, jir ah, quudin jiray cuntooyin kala duwan.

Marka gudbay kasta oo shakhsiyaad kale oo aan si buuxda u lumay awood u leh inay sameeyaan farcankaaga bacrin ah. Sida baadhayaashu, masaafo weyn oo u dhexeeya jasiiradaha iyo kala duwanaanta flora iyo dubato keentay in formation of dhowr dacawo, ka dibna waxaad fartaan Wannaagga galay noocyada kala gooni ah. Waxaan ka fikiray line kale oo horumar, taasoo keentay in formation of noocyada cusub, taas oo dhan u guurayaan duur hadda jira. Tusaalayaasha aannu kor ku wada hadleen, muujiyaan doorka muhiimka ah ee hababka da'ayeen si looga hortago in suurtagalnimada, iskutallaabtiisana ha u dhexeeya dadka kala duwan ee noolaha in ugu danbeyn keenaysaa in muuqaalka kore ee unugyada cusub nidaamsan.
