Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The average rate at which a species' genome accumulates mutations, used to measure their evolutionary divergence and in other calculations.
- ‘We introduce a parametric model that relaxes the molecular clock by allowing rates to vary across lineages according to a compound Poisson process.’
- ‘Here, we discuss the usefulness and limitations of molecular clocks in studying avian evolution, with emphasis on the use of an accurate calibration point.’
- ‘The majority of the fossils used for calibration of avian molecular clocks have uncertain phylogenetic relationships.’
- ‘Before we can draw inferences from a molecular clock, we must calibrate its ‘ticking rate.’’
- ‘Divergence times of living species, estimated from molecular clocks, have the potential to constrain hypotheses of the relationships of fossil species.’
We take a look at several popular, though confusing, punctuation marks.
