We report ages for nine sites from varied climatic and ecological zones across\r\nsouthern Africa that show that both industries were short-lived (5000 years or less), separated by\r\nabout 7000 years, and coeval with genetic estimates of population expansion and exit times.\r\nComparison with climatic records shows that these bursts of innovative behavior cannot be\r\nexplained by environmental factors alone.","type":"researchdata","resources":[{"description":"","format":"PDF","url":"http://crc806db.uni-koeln.de/data/Phase_1/A/A1/data/000/Jacobs_etal_2008_Ages_MSA_Southern_Africa_Human_Behavior_Dispersal.pdf","created":"2014-08-19T14:57:30.701849","state":"active","package_id":"b429f7a6-5195-4737-b93e-58a538642b15","last_modified":"2021-10-23T07:10:14","id":"ce48a9aa-1bd7-495e-8adb-64e3bdfddeaa","name":"Jacobs_etal_2008_Ages_MSA_Southern_Africa_Human_Behavior_Dispersal.pdf"}],"tags":[{"name":"chronology"},{"name":"dispersal"},{"name":"howiesons poort"},{"name":"human behavior"},{"name":"msa"},{"name":"southern africa"},{"name":"still bay"}],"extras":[{"key":"bibtex:address","value":""},{"key":"bibtex:author","value":"Zenobia Jacobs and Richard G.
