Paleoparasitology and the antiquity of human host-parasite relationships

open access: yesMemorias do Instituto Oswaldo Cruz, 2000
Paleoparasitology may be developed as a new tool to parasite evolution studies. DNA sequences dated thousand years ago, recovered from archaeological material, means the possibility to study parasite-host relationship coevolution through time.
