| Résumé : | Life appeared on earth 3.5 milliards years ago. Primitive cells were formed by incorporating endosymbiotic forms of bacteria. Traces of parasitism were clearly identified at each step of the Evolution and in particular during the oldest antiquity. The host-parasite coexistence has induced the emergence of remarkable genetic and behavioural modifications of which we give some examples. ©1998, Elsevier, Paris. |
