Evolution and classification of organism are interlinked give reason to justify this statement |
|
Answer» 1.Different life forms have evolved during the course of evolution.Classification deals with the grouping of these life forms intogroups and sub groups based on similarities and differences.\uf0b72. The more characteristics any two species have in common,more closely they are related.\uf0b7 3.Thus classification helps in tracing the evolutionary relationshipbetween the two organisms. Hence, evolution and classificationare interlinked. Every species or organisms has inbuilt tendency for genetic variation which plays an important role in the origin of new species and forms the the basis for evolution.The more characteristics two species have in common, the more closely they are related. And they are likely to have a a common ancestor more recently. Classification of organisms necessarily involves, organizing them in different groups, based on the similarities and differences of characteristics. Classifying organisms helps us in recognizing the basic arrangement of a hierarchical structure among diverse species. So, classification of species is a reflection of their evolutionary relationship. Thus, we can say that evolution and classification are interlinked. |

Natural selection and speciation leads to evolution justify this statement. |
|
Answer» Hence both natural selection and speciation leads to evolution of an organism. Yes because a species is a group of population which reproductly isolated from the rest of the poulation. The origin of species from pre-existing one leads to speciation of species. If nature allow that species to survive then they can reproduce to give rise to new characters which is known as variation. |
