Timeline of the development of tectonophysics (before 1954) scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. Mainly Charles Lyell, Harold Jeffreys, James D. Dana, Charles Schuchert, Chester Longwell, and the conflict with the Axis powers slowed down the acceptance of continental drifting . Timeline of the development of tectonophysics (before 1954) The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data. The fixist/ Pratt-Hayford isostasy, the contracting Earth and the expanding Earth concepts had many flaws as well. The idea of continents
One-name study and group it geographically, approximately representing the different family groups. Others attempt to reconstruct lineages. In most one-name studies, a united lineage will not be discovered, but broad perspectives can be achieved, giving clues to name origins and migrations. Many researchers are motivated to go beyond the one-name-study stage and to compile fully researched, single-family histories of some of the families they discover. Accessibility of the data required for a one-name study varies from country to country. Where civil registration indexes are open to public search, they may not be online or gathered in the national capital, but are scattered
