Famous Quotes By Marcia Bjornerud
According to pioneering microbiologist Lynn Margulis, "fully 10 percent of our own dry body weight consists of bacteria, some of which, although they are not a congenital part of our bodies, we can't live without." In fact, a healthy human body has more bacterial cells than animal cells (bacterial cells are far smaller). Our own bodies are in some ways microcosms of the biosphere as a whole. — Marcia Bjornerud
