Fig. 1From: Reconstruction of avian ancestral karyotypes reveals differences in the evolutionary history of macro- and microchromosomesPhylogenetic tree of descendant species and reconstructed ancestors [13]. Branch colour represents rearrangement rates in RACFs (EBRs/MY). Acronyms on nodes represent ancestor names as shown in Table 1. AVI: Avian; NEO: Neognathae; NEA: Neoavian; PAS: Passerea; TAG: Telluraves & Aequornithia & Gruae; TAE: Telluraves & Aequornithia; TEL: Telluraves; EUF: Eufalconimorphae; PSI: Psittacopasserae; PAE: Passeriformes; PAR: Passeri; PPA: Passeroidea & Paroidea; PAO: Passeroidea; ETF: Estrildidae & Thraupidae & Fringillidae. Numbers next to species names indicate diploid number of chromosomes in karyotypes (if known)Back to article page
