Evidence for periodicities in the extinction record? Response to Melott
  & Bambach [arXiv:1307.1884]
  In a recent paper, we applied time series analysis methods to study the
possible influence of the solar motion through the Galaxy on terrestrial
extinction (Feng & Bailer-Jones 2013). We drew conclusions about the relative
probabilities of how well different models explain the geological extinction
record. We found no strong evidence for either a periodicity in the extinction
record or for a link between the solar orbit and this extinction record. In
response to this, Melott & Bambach (2013) dedicate the majority of their
article to criticizing our analysis. Their main objection is to evidence-based
model comparison. Here we deal with their criticisms one by one, and show that
they are largely misplaced, leaving our conclusions unaffected. The bottom line
is that although one can get a periodic model at some period to fit the
extinction data, there are other models which explain the data better.
