Evolutionary History of Terrestrial Pathogens and Endoparasites as Revealed in Fossils and Subfossils

Abstract EN

The present work uses fossils and subfossils to decipher the origin and evolution of terrestrial pathogens and endoparasites.

Fossils, as interpreted by morphology or specific features of their hosts, furnish minimum dates for the origin of infectious agents, coevolution with hosts, and geographical locations.

Subfossils, those that can be C14 dated (roughly under 50,000 years) and are identified by morphology as well as molecular and immunological techniques, provide time periods when humans became infected with various diseases.

The pathogen groups surveyed include viruses, bacteria, protozoa, fungi, and select multicellular endoparasites including nematodes, trematodes, cestodes, and insect parasitoids in the terrestrial environment.
