Continental drift orogeny at the boundaries of convection cells. By 1967, barely two decades after discovery of the mid-oceanic rifts, and a decade after discovery of the striping, plate tectonics had become axiomatic to modern geophysics. In addition, Marie Tharp, in collaboration with Bruce Heezen, (who initially ridiculed Marie's observations that her maps confirmed continental drift theory), provided essential corroboration, using her skills in cartography and seismographic data, to confirm the theory. Evidence for the movement of continents on tectonic plates is now extensive. Similar plant and animal fossils are found around the shores of different continents, suggesting that they were once
The Association for the Study of Play the University of Illinois at Urbana–Champaign (then the University of Illinois) and an affiliate professor in the Department of Anthropology. The scholars who met there formed the "Cultural Anthropology of Play Reprint Society." The next year, Michael Salter organized the first formal meeting of the new organization at the University of Western Ontario during the North American Society for Sport History (NASSH) convention. Participants renamed the organization "The Association for the Anthropological Study of Play" and elected B. Allan Tindall as president. In 1987, the organization changed its name to "The Association for the Study of Play" (TASP). The proceedings
