Abstract
We hypothesize that components of microbiomes associated with humans and higher life-forms may be continually replenished from space. Examination of stratospheric dust using culture-independent gene-mapping techniques could reveal their possible existence and thus demonstrate unequivocally our evolutionary connection with the external universe.

The role of symbiotic microorganisms, in the human gut has been recognized for many years
How did the human microbiomes arise in the first place? Is it the outcome of millions of years of co-evolution between evolved organisms and an ever-changing population of environmental bacteria and viruses? Or is a population of microbial/viral entities identifiable with microbiomes continuously being replenished from space?
Summary
“Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.” - Sir Arthur Conan Doyle. The role of symbiotic microorganisms, in the human gut has been recognized for many years. Advances in culture-independent gene sequencing techniques have made possible a better understanding of this somewhat enigmatic entity its origin and evolutionary impact remains unclear [2,3].
