Craig Venter’s studies on microbial diversity have correctly pointed out that the number of species may be less important than their diversity and roles in the Earth’s biosphere. Venter concluded from a two-year study of marine microbes that for every 200 miles of ocean, 85 percent of the species, judged by unique genetic sequences, changed. The ocean appears to contain millions of subenvironments rather than one massive marine environment, and each milliliter holds millions of bacteria. The actual number of bacteria in the oceans alone may exceed any previous estimates for the entire planet.
