The test database has about 1000 articles in it which are spread through several years.
The data has been normalised to acount for the number of articles in the databse per year.
There seems to be a downward trend in most of traditional methods of phylogenetic inference.
e.g. Neighbor-joining (neighbour-joining), maximum parsimony, maximum likelihood.
And yet a quite obvious upturn in the use of bayesian inference of phylogeny.
This would certainly fit with recent trends in phylogenetics.
