To elaborate: The reason that understanding of evolution is indispensable to modern medical research. Introduction: Real advancements in the medical field were visible after the discovery of the causative agents of plague and malaria. Malaria is the most widespread disease which is still affecting the millions of people every year. Medical research emphasizes about the clarity of life cycle of the parasite. Since parasites often evolve with their host, evolution of parasite, and vectors. Hence, mutations in parasite can be deciphered only after evolutionary information about host and parasite.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Use examples associated with the malaria parasite, Plasmodium, to illustrate why an understanding of evolution is indispensable to modern medical research. (Hint: Be sure to include serial endosymbiosis and drug resistance in your answer.)

Wolbachia is a genus of bacteria that infect cells of invertebrates. Surveys have found that up to a fifth of insect species have at least some individuals infected with Wolbachia. Pathogen or parasite? This endosymbiont (a symbiont that lives inside its host) bacteria can have many effects on its host, including killing offspring and changing the sex of offspring. Ary Hoffmann from the University of Melbourne in Australia, Michael Turelli from the University of California at Davis, and their associates have been studying Wolbachia infections in populations of Drosophila simulans from California. From the initial infection around 1980, Wolbachia infection spread northward across the state during the 1980s and 1990s. The most striking manifestation of infection in this fly species is cytoplasmic incompatibility: offspring produced in crosses where males are infected and the females are uninfected tend to die early in development. In crosses between infected males and infected females,…

The theory of the endosymbiotic origin of mitochondria and chloroplasts was first proposed by the biologist Lynn Which of the following statements provides support for the theory of endosymbiosis? 1. All the genes found in chloroplasts are homologous to genes found in the nucleus of eukaryotic cell. 2. Mitochondria contain their own ribosomes. 3. Proteins need a targeting sequence to be imported into a chloroplast. 4. Mitochondria can generate a proton gradient and harness it to synthesize ATP. O A. 1, 2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct.
