This paper concludes that the perceived acceleration in the rate of 
evolution in relatively recent timescales or for short intensively 
studied periods of time are due to "noise" in the data.  The noise seems 
to be the normal distribution of variation within any existing 
population and what was found as fossils of past species, and even 
errors of base calling for sequencing.  I guess when you sample multiple 
individuals that died within a relatively short period of time that the 
then existing range of variation in the population gets haphazardly 
sampled in some temporal order and even randomizing the samples relative 
to time results in the same acceleration rate.

For DNA sequence you would be dealing with standing genetic variation 
within a population and the fact that the shorter the time period under 
study the fewer differences that you would observe between individuals, 
so sequencing errors might inflate differences for short periods of time 
more than for much longer periods of time, and the standing genetic 
variation found within the population might not be sampled enough to 
know where an individual fell in the distribution of variation that existed.

Probably not unexpected, but something that seems to have been missed.
