Welcome to ComplexUs!

I’m Zach Adam, a paleontologist, prebiotic chemist, and engineer fascinated by two of the biggest jumps in complexity known to have occurred in the history of our planet: the origins of life and the origins of the eukaryotic cell.

My most significant contributions so far have been to discover:

  • New pathways to synthesize the sugar, nucleotide precursors and condensing/leaving agents alongside one another in a single pot via irradiation of water, salt and HCN (published in PNAS, Scientific Reports and ChemistrySelect)
  • Indications that simple compound irradiation can drive self-organization of monomer synthesis: a non-living predecessor to living systems, and perhaps a new compelling paradigm for prebiotic chemistry experimentation (published in Scientific Reports
  • New techniques in molecular biology to the application of problems in Precambrian paleobiology (published in Geobiology)
  • New assemblages of incredibly well-preserved, complex, eukaryotic microfossils in the Greyson Formation of the Belt Supergroup, providing new evidence that links these fossils with existing eukaryote lineages (published in Geology)
  • New sources of well-preserved fossils in the Chamberlain Formation of the Belt Supergroup, supporting indications that even the earliest eukaryotes were partitioned into distinct groupings in different environments (published in GSA v.522)

I’m currently an Associate Staff Scientist in the Department of Planetary Sciences at the University of Arizona. My work has been funded by the Simons Collaboration on the Origins of Life, the Agouron Institute, NASA and the National Science Foundation, with future work to be funded by the John Templeton Foundation.

Within this site, you’ll find information about some really cool fossil discoveries and prebiotic chemistry experiments, enjoy!
