a A Neighbour-joining tree based on an alignment of annotated Laurasiatherian TAS2Rs (with orthologs representing all the 28 clades of Euarchontoglires TAS2Rs as outgroups) is shown. The clades not found (TAS2R6 and TAS2R13) and the pseudogenized clade TAS2R301 are underlined. The massive duplication events in different orders are marked by shadow blocks. b The dotplots showing that the duplication in the genomic region NW_004545902.1 of the common shrew resulted in increased gene copy numbers of clades TAS2R7 and TAS2R8
