antibiotico Francalacci and Bustamante
used a relatively new way of calculating
the rate of DNA change. They used dates
determined by archaeology as mile
markers. Francalacci and his lab, for
example, used the spread of people over
the Italian island of Sardinia 7,700
years ago as their mile marker. They
sampled DNA from 1,204 Sardinian men,
calculated how different those men's Y
chromosomes were from each other, and
then calculated the mutation rate
required for Sardinian diversity to have
arisen over 7,700 years. Bustamante and
his colleagues did something similar
with the peopling of the Americas 15,000
years ago.
