7 वी - महाराष्ट्र बोर्ड - सायन्स टेस्ट - चॅप्टर 1 - The Living World - Adaptation and Classification
15) पृथ्वीवर 8 करोड़ 70 लाख सजीव आहेत, सजीवांमधील ही प्रचंड विविधता लक्षात घेता, त्यांचा अभ्यास करणे सोपे व्हावे म्हणून त्यांचे वर्गीकरण केले जाते.
16) यासाठी Carl Linnaeus यांनी सजीवांना नाव देण्यासाठी Binomial Nomenclature ची पद्धत शोधून काढली.
17) या पद्धतीनुसार प्रत्येक सजीवाला एक Scientific Name दिले जाते, ज्यामध्ये दोन भाग असतात – पहिला भाग Genus दर्शवतो तर दुसरा भाग Species दर्शवतो.
18) उदा. माणसाचे Scientific Name - Homo sapiens असे आहे.
119) थोडक्यात सांगायचे तर, हे प्रकरण आपल्याला हे शिकवते की कशा प्रकारे प्रत्येक सजीव आपल्या आजूबाजूच्या वातावरणात टिकून राहण्यासाठी स्वतःमध्ये बदल घडवून आणतो आणि निसर्गाचा एक भाग बनतो.
