Parasite - an organism that benefits by living in/on a host organism and deriving nutrients at the host's expense. Host - an organism in/on which another organism lives. Protozoa - a group of single-celled microscopic animals (not bacteria or viruses) that includes the Plasmodium species. Plasmodium - a genus of parasitic protozoa, many of which cause malaria in their hosts. Four species regularly infect humans: P. falciparum, P. vivax, P. malariae, & P. ovale. P. falciparum - the Plasmodium species that kills the most people, by causing malignant malaria, the most dangerous form of malaria. Anopheles gambiae - a ‘complex' of at least seven species of mosquitoes that are the main vectors of P. falciparum in sub-Saharan Africa. Species complex - a group of closely related species that look so similar that the boundaries between them are often unclear. Hunting and gathering - depending primarily on wild foods for subsistence Paleontology - the study of fossils and what fossils tell us about the past, about evolution, and about how humans fit into the world. ___________________________________________ Credits (and Twitter handles): Script Writer: Alex Reich (@alexhreich) Script Editor: Emily Elert (@eelert) Video Illustrator: Qingyang Chen Video Director: Emily Elert (@eelert) Video Narrator: Kate Yoshida (@KateYoshida) With Contributions From: Henry Reich, Ever Salazar, Peter Reich, David Goldenberg Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder _________________________________________ Like our videos?
