In the 1700s, organisms were broken into only two kingdoms - animalia and vegetabilia. throughout the next few hundred years, the name plantae replaced vegetabilia, and other kingdoms began to emerge. finally, in the 1900s, the currently accepted six kingdom system was adopted. currently, the kingdoms include: plantae, animalia, fungi, protista, archaebacteria, and eubacteria. the development of the current classification system is probably due to

The development of the current classification system is probably due to similarities or common characteristics.

Explanation:

Similarities and common characteristics used for classification into kingdoms are: mode of reproduction, cell type and nutrition.So the major characteristics of those 6 kingdoms are:

Animalia-usually sexual reproduction, usually multicellular, eukaryotic, heterotrophsPlantae-both sexual and asexual reproduction, multicellular, eukaryotic, autotrophs (photosynthetic)Fungi-both sexual and asexual reproduction, multicellular, eukaryotic, heterotrophs (saprobs)Protista-usually asexual reproduction, often unicllular, eukaryotic, autotrophic (photosynthetic) or heterotrophic (parasites)Archaebacteria-asexual reproduction, unicellular, prokaryotic, autotrophicBacteria-asexual reproduction, unicellular, prokaryotic, autotrophic
