Abstract

Microbiomes: A Possible Space Component?

Chandra Wickramasinghe, Ananda Nimalasuriya, Milton Wainwright and Gensuke Tokoro

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.
