Estimated dates of divergence for ticks, Anaplasma, Ehrlichia and birds. The maximum likelihood tree of the genera Anaplasma and Ehrlichia was constructed using 16S rRNA nucleotide sequences (see Additional file 1). Molecular clock analyses were performed for major tick lineages using CYTB amino acid sequences and for Anaplasma and Ehrlichia using 16S rRNA nucleotide sequences (see Additional file 1). Divergence times of Sauropsida [44], Dinosaurs [21] and birds [24, 25], including Passeriformes birds [25], are shown. *Diversification of Ixodes, excluding Australian Ixodes. In geological ages line “N” is Neogene
