The strong influence of nature on human life during ancient times requires that people must have chosen their habitats based on the limits of their technology, especially of farming technology, and an understanding of natural conditions. To verify this assumption, the correlation between natural environment and habitat placement in the Daegu basin in Korea over the recent Holocene has been investigated. In this paper, we attempt to correlate various changes in the natural environment of the Daegu basin with the location of burial sites, cultivated fields, and residential areas during the Bronze Age, the Iron Age, and the proto-Three Kingdoms Age. We also compared the changes in location and extent of inhabited areas to the development of tools, soil characteristics, and to the climatic changes based on the sea level changes during the Holocene. We conclude that people probably did limit their habitats according to their understanding of their environment and their technology.

... The Sejukri site (35 27 0 57 00 N 129 21 0 11 00 E) represents Initial and Early Neolithic adaptation to a large lagoon environment, dating back to 7500 to 6000 cal BP. The site is currently located on the edge of an inner bay along the east coast, but a lagoon was formed in front of the site by a long stretch of sandbar throughout the Early and Middle Holocene (Hwang and Yoon 2002). Among the more than 10 taxa of shellfish and fish identified at Sejukri, species of shallow waters and lagoon were dominant (Dongguk University Museum 2008). ...

... This leads to the classification of these areas as pediments rather than traditional alluvial fans. The distinction between pediments and alluvial fans based on sediment thickness has been a topic of global discussion, and recent studies have undertaken comparisons between Korean alluvial fans and those in other countries (Bull 1977, Yoon et al. 2005, Yoon et al. 2010). ...

... Cyclobalanopsis, and an increase in the abundance of boreal conifer trees, may represent dry conditions. The dominance of conifer pollen in the pollen assemblage is somewhat contrary to previous studies on terrestrial sediments in the Korean Peninsula, which reported the predominance of herbs together with cold-temperate trees (Yoon and Jo, 1996;Yi and Kim, 2007). This difference can be explained by the terrestrial lands surrounding the East Sea having no lowland flats for grasses to grow. ...

... By using improved data, we have solved the compositional linkage between river sediments and their source rocks, which has been unclear in previous studies. (Nesbitt and Young, 1984) for the compositions of KR and CR river sediments (residual fraction), upper continental crust (UCC, McLennan, 2001), granite and granodioritic rocks (Nesbitt and Young, 1984;Bahlburg and Dobrzinski, 2009), Korean river fine bulk sediments (Li and Yang, 2010), paleosol (Yoon et al., 2007) and granites (Lee and Kim, 2012), and Chinese loess and paleosol (Jahn et al., 2001;Selvaraj and Chen, 2006) and rocks (Selvaraj and Chen, 2006). Solid arrows represent the weathering trends of Chinese (Arrow 1) and Korean river sediments (Arrow 2), with source materials, and dashed arrow indicates a predicted weathering trend of river sediments. ...

... To date, microfossil analyses of Holocene sea level changes have been conducted from sediments of estuarine or river mouths distributed along the west coast of South Korea (Jo, 1980;Jo et al., 1994;Hwang et al., 1997;Hwang, 1998;Ryu et al., 2005Ryu et al., , 2007Jun et al., 2010;Bak, in this volume). These include the diatom study carried out from the Ilsan alluvial plain (Hwang, 1998) and from the alluvial plain in the middle to lower reach of the Pyeongtaek Dodaecheon stream (Hwang et al., 1997). ...

... On the Peninsula, many upland landscapes and Late Pleistocene-Holocene flat-lying paleosol sequences have been exposed, including parent sediments of eolian, alluvial, fluvial, or mixed origins [49][50][51] . Bulk k data have often been reported for paleosol sequences [52][53][54] . Additionally, many paleosol sequences have archeological significance for understanding modern human evolution and settlement history. ...

... The mid-Holocene witnessed a rapid rise in sea levels between approximately 7 and 4 kyr BP, gradually reaching present levels ( Fig. 2a; Bloom and Park, 1985;Chough et al., 2004;Lee and Chang, 2015). Conversely, some authors claimed that mid-Holocene sea levels were 1-2 m higher than at present ( Fig. 2b; Hwang et al., 1997;Song et al., 2018a), prompting ongoing debate. The KP, situated in the far-field region, has diverse coastal environments. ...

... The nationwide distribution of Pinus, mainly diploxyon, might imply a continuation of a mild climate during the hypsi-thermal or climatic optimum periods in R.O.K. However, Chang and Kim (1982) and Yoon and Hwang (2001) suggested that the hypsi-thermal period of the Holocene in Korea existed between 7500e4000 BP and 8000e5000 BP, respectively. ...
