Predator-Prey Relationships: Coevolution versus Escalation Species on Earth interact in many different ways (Abrams‚ 2000). These interactions have evolved over millions of years to become an incredibly complex web of inter-species relationships and understanding these relationships enables science to model future species interactions (Abrams‚ 2000). From symbiosis to parasitism‚ Earth seems to have every type of relationship imaginable (Dietl and Kelley‚ 2002). One of the most intriguing

of these worms is the periodic swarming of the microfilariae in the bloodstream. In most species swarming takes place at night. The embryos can be taken up by an insect only when they are in a human’s bloodstream. They develope into infective larvae in the insect‚ which is the intermediate host. These hosts are various genera of mosquitoes‚ notably A?des‚ Anopheles‚ and Culex. Within 10 to 11 days after ingestion by a human skin they migrate to the lymphayic vessels where they mature and
