Fikradda ah noocyada iyo dadka, views casriga on speciation shuruudaha nooca,

Habdhismada of noolaha galay fasallo gaar ah loo ogol yahay si ay u sameeyaan fikrad ka mid ah kooxaha kala duwan ee noocyada degganu caalamka. Dabcan, waxaa jira kuwa is burinaya badan oo xataa aragtiyaha casriga ah ee asal ahaan evolutionary noocyada ugu, laakiin soocidda aasaasiga ah waxaa aasaas, oo kor u xigsiin foomamka nool. Laakiin waqtigaan tirada wakiilada oo ka mid ah kooxaha kala duwan ku tilmaamay dubato dhowr jeer kor u kacay xiiso leh, fikradda guud ee noocyada dawadu sayniska Karl Linney soo laabtay 1753. Iyo in aan ku xuso horumarka joogta ah habab si formation of Taxonomy iyo simayo ee dhirta iyo xayawaanka.

fikradaha guud ee noocyada iyo dadka

Ku hoos gambanaya arimo fahamsan yahay sida set oo ah shakhsiyaadka ayaa dhaxlay set oo ah muuqaalada caadi ah in la qeexo ah morphological, jir, noolaha iyo qaababka kale. Dhab ahaantii, set this of sifooyinka oo kuu ogolaanaya inaad si loo doorto noolaha nool shaqsi ee dadka ah. Fikradda classical noocyada bayoolaji sidoo kale bixisaa in wakiilkiisa in habka nolosha mashquulin isla aagga. Isla mar ahaantaana view waa mid ka mid ah noocyada ugu muhiimsan kaas oo noolaha u habeysan yihiin.

Laakiin taasi macnaheedu ma aha in mid ka mid ah xirfad caadiga ah si fudud loogu ogaan karo aqoonsiga shaqsi gaar ah ay u nooc gaar ah. Si taas loo gaaro, iyo waxa uu siiyaa tiro ka mid ah shuruudaha by kaas oo shakhsiyaadka la galeen qaybaha kala duwan ee Taxonomy noocyada. Taa baddalkeeda, dadka waa a collection ah oo ay shakhsiyaad ka tirsan noocyada la mid ah. tirsanaan koox Tani waxay sidoo kale keentaa balliga hiddo-caadi ah, awood u leh inay soo saari farcankaaga waarta iyo go'doon ka noocyada kale.

shuruudaha nooca

Dhab ahaan baan u xusay in shuruudaha aasaasiga ah ee lagu soo bandhigay muuqaalada gaarka ah ee kooxaha. iyaga ka mid aasaasiga ah waa kala bixiyc morphological, kaas oo ku salaysan kala duwanaanshaha dibadda u dhexeeya noocyada. Tani set of sifooyinka u ogolaanaya in ay soo saaraan kala noolaha isagoo sifooyinka kala duwan marka la eego sifooyinka morphological gudaha ama dibadda. Laakiin waxaa lagama maarmaan ma aha in laga saaro suurtagalnimada inuu qabo calaamadaha adag qeexay in ay yihiin dareemi keliya ee geeddi-socodka ah ee la arkay ay muddo dheer.

bixiyc juquraafi sidoo kale dhameystirta fikradda guud ee noocyada. Shuruudaha for noocyada noocan ah waxay ku salaysan yihiin xaqiiqda ah in xubno ka mid ah koox kasta waxay leeyihiin meel gaar ah guryaha caadiga ah. Tani waa degaanka dabiiciga ah, kaas oo si gooni gooni ah la tixgelin doonaa.

Faraj kale oo muhiim ah waa set feature ee nafsaaniga ah iyo lagmamaarmaanna. In la eego isku halaynta waa kala bixiyc runta ah, tan iyo markii ay ku salaysan yahay farqiga u dhexeeya noocyada kala duwan ee geedi socodka lagmamaarmaanna u kala duwan in si siman dhacaan qaybaha la mid ah noolaha.

kala duwan oo ka mid ah noocyada ugu

Meesha waa meel bannaan oo lagu qeexay xuduudaha juqraafi ah oo loo qaybiyey qaab la taaban karo. Iyada oo ku saleysan dabeecadaha biosphere ee degaanka, waxaa suurtagal ah in gebagebo ah oo ku saabsan cabbirka iyo qaababka in la kala saaro meel this degan. Dhab ahaantii, aagga loo isticmaali karaa sida Faraj ee go'aaminta xubin buuxda gaarka ah ee nooc gaar ah, laakiin waxaa muhiim ah in ay tixgeliyaan qaar ka mid ah Gudigga ah.

Marka hore, waa wax iska cad in mid ka mid degaanka noolaan karaan wakiillo ka noocyada kala duwan. Marka labaad, fikradda guud ee noocyada loo maleeyo in bixiyc juquraafi iyo ma laga yaabaa in la la'yahay, haddii aynu ka hadlayno ugu cosmopolitans-ka loo yaqaan. noocyada Tani, taasoo aragti ahaan loo qaybin karaa guud ahaan caalamka, iyadoo aan loo eegin dhul, muuqaalada cimilada, iyo D. sidaas on. Cilmibaadhayaasha ayaa sidoo kale go'doonsan bystrorasselyayuschiesya koox shakhsiyaad ka mid ah noocyada kala duwan waxaa laga yaabaa in la beddelo meesha si xirfadlayaasha aadan waqti si loo ogaado dabeecadihiisa. shakhsiyaadka Kuwanu waa guri-dukhsiga iyo shimbirrood.

Fikradda ah noocyada iyo ecology dadweynaha

In view of dadka deegaanka iyo waxaa loo arkaa in macnaha guud ee dhexgalka ah oo ay shakhsiyaad kooxaha kale. Beegyada uu ugu weyn ee daraasadda of ecology noocyada waa size dadweynaha, nooca cuntada, degaanka, muddo taranka, iyo wixii la mid ah .. Kuwani iyo tilmaamayaasha kale ogolaan khubaro ah si ay u yeelaan dadka qaar niches. Si toos ah kala bixiyc ethological waa la dhimay si loo ogaado kala duwanaanta dabeecadda ka mid ah wakiilo ka noocyada kala duwan. Sidoo kale, fikirka ah noocyada in ecology ee xaaladaha noolaha iyo abiotic go'an dhismaha, halkaas oo dadweynaha waxaad fartaan Wannaagga oo ku habboon nolosha.

Geedi socodka ah ee speciation

formation of noocyada cusub dhacdaa siyaabo kala duwan, kuwaas oo loo qoondeeyey in laba kooxood oo ugu waaweyn. Sida caadiga ah, natiijada speciation ka horumar wax-u phyletic. Iyadoo la tixraacayo fikradda ah ee geedi socodka gudahood dadka hal danbeyn keeni xaqiiqada ah qabsashada in deegaanka gaar ah noolaha kordho, taasoo keentay in isbedel la taaban karo ka dhacaan sifooyinka kooxda.

Foomka labaad ee speciation ku salaysan yahay tageynaa kooxda labo qaybood. Sida kor ku xusan, fikradda ku lug leedahay isticmaalka dhowr nooc oo calaamooyin ku amro shaqsiyaadka gol leeyahay in ay ka mid noqoshada dadka gaar ah. dhib ugu weyn si hufan kala saaro, kuwaas oo sababa bandhigay of cholesterol by speciation.

fikradaha casriga ah ee speciation

Waxaa jira laba waji ee qeexidda speciation by tageynaa kooxda. Waxaa speciation allopatric iyo sympatric. In kiiska ugu horeysay waxay ka dhigan tahay ballaarinta hoygii asalka ah ee foomka ku hoos jira xaalad ka mid ah dadka joogaanse dheer iyada oo go'doomin juquraafi. xaalad muhiim u ah sifooyinka of formation, ku filan in ay ka jaraan tijaabooyinka go'doonsan in koox gaar ah, waxaa la demiyo ka dadka wakiilada ilaha aasaasiga ah. separation juquraafi Dabiiciga laga yaabaa inuu dhaco inta lagu jiro tiixtiix kaca, cidhiidhi badda iyo la mid ah. D.

Si loo go'aamiyo foomamka sympatric of formation of kooxo cusub, waa in la ogaadaa in fikradda ah noocyada ka mid ah muhiimadda badan ee takhasuska cunto ah oo ay shakhsiyaad. qeybinta in ku saleysan sababaha iyo mabaadi'da formation of noocyada cusub ee kooxda asalka ah.

gunaanad

Weli jira Taxonomy maanta ee noocyada of noolaha waa ka fog kaamil ah. Xaqiiqada ah in xataa qalabka-farsamada casriga ah iyo qaababka ay u aqoonsadaan astaamaha shaqsiyaadka kala duwan markasta suurtagal ma aha si sax ah oo ku filan si ay u aqoonsadaan sida wakiillo ka category gaar ah.

Waxaa la beddelo fikirka aad ee noocyada, dhamaystirayaa dhinacyo cusub ee sifooyinka nafleyda, juquraafi iyo dhawrista. Dabcan, meel gaarka ah ayaa weli degan sifooyinka nafsaaniga ah ee noolaha ku nool, taas oo samaysa feature aasaasiga dhigay formation of systematics. Adkaata kala soocidda sida caadiga ah dersaan marka foomam cusub, taagan ee links dhexe u dhexeeya noocyada kala duwan.
