उत्तर
- You have seen earlier that categories like species, genus, and families are based on a number of similar characters.
- Generally, order and other higher taxonomic categories are identified based on the aggregates of characters. Order, being a higher category, is the assemblage of families that exhibit a few similar characters.
- The similar characters are fewer in number as compared to the different genera included in a family. Plant families like Convolvulaceae, Solanaceae are included in the order Polymoniales, mainly based on their floral characters.
- The animal order, Carnivora, includes families like Felidae and Canidae.
