Abstract It is nearly 30 years since the first decisive evidence of microbial morphologies in carbonaceous chondrites was discovered and reported by Hans Dieter Pflug. In addition to morphology, other data, notably laser mass spectroscopy, served to confirm the identification of such structures as putative bacterial fossils. Recent examinations of cometary dust collected in the stratosphere and further studies of carbonaceous meteorites reaffirm the presence of putative microbial fossils. Since… Expand
Recurrent Dreams of Life in Meteorites
The debate on life in meteorites has entered its eighth episode, with recurrent themes and arguments. We suggest: (1) that deliberate contamination of meteorite specimens be used as a control; (2)Expand
Convergence to panspermia
New discoveries in astronomy and biology continue to point to Panspermia as the most likely mode of the origin of life on Earth. This paper builds upon the work done by W.M. Napier, 2004 1 , andExpand
The Origin of Life on Earth, the Panspermia Hypothesis and Cosmological DNA Synthesis
The process of the rapid origin of life on Earth is analyzed, taking into account the evolution of our Sun (the beginning of thermonuclear reactions). Given the knowledge about DNA, viruses and theExpand
Organism-substrate interactions and astrobiology: Potential, models and methods
Abstract Organism-substrate interactions and their products – biogenic structures – are important biosignatures on Earth. This study discusses the application of ichnology – the study ofExpand

Life was most likely present on Earth as early as 3.5 GYA and probably made its first appearance around 4 GYA. Alkaline hydrothermal vents discovered in 2000 are presently considered a likely settingExpand
The Transition from Earth-centred Biology to Cosmic Life#
A paradigm shift with potentially profound implications has been taking place over the past 3 decades. The convergence of research in diverse disciplines points to life being a cosmic phenomenon. AExpand
Ramifications of the diverse mRNA patterns in Acanthamoeba royreba
It is shown that the proteins and mRNA content associated with A. royreba are extremely diverse and represent multiple Kingdoms, Orders, Phyla, and Genera from around the globe, which leads to a discussion regarding the possible role of this amoebae as an immunological gatekeeper protecting fetal or malignant tissue from destruction and its potential as a vehicle for panspermia.

Atlas of bacteriomorphs in carbonaceous chondrites
During the past few years, there has appeared much new and interesting data concerning the distribution of bacteriomorphic structures in both meteorites (carbonaceous chondrites) and in Earth rocksExpand
High molecular diversity of extraterrestrial organic matter in Murchison meteorite revealed 40 years after its fall
It is demonstrated that a nontargeted ultrahigh-resolution molecular analysis of the solvent-accessible organic fraction of Murchison extracted under mild conditions allows one to extend its indigenous chemical diversity to tens of thousands of different molecular compositions and likely millions of diverse structures.

The origin of life in comets
Abstract Mechanisms of interstellar panspermia have recently been identified whereby life, wherever it has originated, will disperse throughout the habitable zone of the Galaxy within a few billionExpand
Carbon Compounds in Interplanetary Dust: Evidence for Formation by Heterogeneous Catalysis
Associations of carbonaceous material with iron-nickel alloy, carbides, and oxides were identified by analytical electron microscopy in ten unmelted chondritic porous micrometeorites from the earth's stratosphere, suggesting that some of the carbon in the chondrite porous subset of interplanetary dust was emplaced through heterogeneous catalysis.

Analysis of fossil organic nanostructures: terrestrial and extraterrestrial
A review is presented of the currently available evidence of life in the Precambrian, with special reference to ultrafine morphologies of the size range 0.1 - 3 micrometers . The particles are to beExpand
Study of putative microfossils in space dust from the stratosphere
Abstract Interplanetary dust particles (IDPs) were recovered from the stratosphere by a cryosampler flown below a balloon flying at altitudes of 20–41 km. The present study uses high-resolutionExpand
The astrobiological case for our cosmic ancestry
Abstract With steadily mounting evidence that points to a cosmic origin of terrestrial life, a cultural barrier prevails against admitting that such a connection exists. Astronomy continues to revealExpand
Organics Captured from Comet 81P/Wild 2 by the Stardust Spacecraft
The presence of deuterium and nitrogen-15 excesses suggest that some organics have an interstellar/protostellar heritage and a diverse suite of organic compounds is present and identifiable within the returned samples. Expand

It is argued that the Aib is not extra-terrestrial but the indicator of exotic pathogenic microfungi that flourished through this era and implies a significant role for the fungi in the ecology, in species extinction and in driving evolution as the Tertiary period got underway. Expand
