Using insights gleaned from archaeal genomes, Erives elaborated and described a stereochemical model of "proto-anti-codon RNAs" (pacRNAs) [REF].
Erives first presented the pacRNA model at NASAs 2012 Astrobiology Science Conference[REF] and most recently at the 2013 Iowa City Darwin Day festival,[REF] which focused on the origins of life on Earth.
