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 ___________.

During spring in Colorado, ice on the mountain tops melts into water. Some of this water gets trapped in cracks in the mountain rocks. With winter, the water in the cracks refreezes into ice.
