Techniques used in forensic science help discover new molecular fossils
According to a system designed by microbiologist Carl Woese, there are three domains of life on Earth – Bacteria, Archaea and Eukaryota. To date, the distribution of archaea remains unclear especially for geologic periods dating back more than 2 million years. This is because except for halophilic, methanogenic and methanotrophic archaea＊, molecular fossils of archaea are rarely found, while those of bacteria and eukaryote are commonly found.
