Early taxonomists relied upon all EXCEPT which of the following to classify an organism? Analysis of the organism\'s shape (morphology) Analysis of structural and organizational characteristics of the organism Analysis of metabolic (nutritional) characteristics of the organism Genetic analysis of the organism

Solution

\"Genetic analysis of organism\" was not considered while classifying an organism by early taxonomist.

Early or classical or old taxonomy delimitation of species on morphological grounds.

Only one or a few individuals are studied for describing species.

They have studied structural and organisational characters of organisms too.

Hence taxonomists did not relied on genetic analysis of organism.

Where as modern taxonomy considered traits and evidences from all types of studies like morphology, anatomy, cytology,physiology,genetics, biochemistry etc. The concept was developed by \"Huxley\"(1940).

Morphological delimitation replaced by biological delimitation in which various branches of systematics are given due importance. e.g chemotaxonomy,cytotaxonomy, experimental taxonomy, numerical taxonomy. As a result, phylogenetic system of classification developed.
