摘要: The diversity of bacteria in the world is very poorly known. Usually less than one percent from natural communities can be grown laboratory. This has caused us to underestimate bacterial and biased our view communities. tools are now available estimate number species a community difference between Using what data available, I have estimated that thirty grams forest soil contains over half million species. related suggests may more thousand million. suppose explanation for such large simply speciation easy extinction difficult, giving rate higher extinction, leading an ever increasing time. idea justified results recent experimental work evolution.
