1. What does Haile et al in Ancient DNA reveals late survival of mammoth and horse in interior Alaska, reveal?

  • That the use of sedimentary DNA shows that these megafauna persisted in Alaska until 10,500 yr BP, as opposed to 13,000-15,000 yr BP which was shown by LADS
  • SedaDNA showed that megafauna we extinct long before the onset of the Holocene and that they never overlapped with humans for several millenia
  • Claims that the main cause of megafauna extinction was solely down to overkill and other factors such as climate, vegetation, hyper diseases and terrestrial impact did not contribute at all

3. Which is not a key feature of Foote and Raup, Fossil preservation and the stratigraphic ranges of taxa?

  • Reasonable approximations are possible given non exponential duration distributions and temporal and taxonomic variations in preservability
  • The completeness of the fossil record hinders the inference of the evolutionary rates and patterns
  • You can use these relationship to estimate original distributions of taxonomic duration, preservation probable and completeness given the observed range. No data on the occurences is required
  • When preservation is random and the original distribution of durations is exponential, the inference of durations, preservability and completeness is exact.
  • There is a relationship bteween the true taxonomic durations, preservation probability and observed taxonomic durations
