There are mainly two different views on the origin of prokaryotic cyanophyceae algae. One view suggests that the prokaryotie eyanophyceae algae originated on the earth as early as 3,200 million years ago, while the other holds that these organisms existed about 2300–2400 million years ago. Concerning the beginning of eukaryotie organisms, there are even more disputes. Some well-known paleophycologists take the view that the actual appearance of eukaryotic organisms should be reconsidered in the light of the calculation of the diameter of fossil algae from Preeambrian, the experimental results from silicification of present day microorganisms, especially algae, trod the records from the organelle-like bodies collected from Bitter Springs Formation. In China, due to the recent discovery of Laminarites and Trachyminuscula in Sinian Subera of northwestern Hubei Sheng, locality of Preeambrian strata (about 1300–1600 million years ago), and the finding of some microfossil organisms from the same era through researches over the last few years, we propose that the eukaryotic plants originated at least 1600 million years ago.
