Keywords:

  • avian genome evolution - and major events;
  • birds, capturing the attention of naturalists - for their beauty, range of behaviors and their mastery of the air;
  • genomics, a larger role in population - organismal, ecological and evolutionary biology in birds and other animals;
  • demise of repetitive elements and shrinking genome size - largest amniote genome, the red viscacha rat (Tympanoctomys barrerae);
  • diagram of events in evolution of the avian genome - the tree based on a phylogenetic analysis of 19 nuclear genes;
  • structure and organization of organism's chromosomes (its karyotype);
  • genome size variation - within modern birds (Neornithes);
  • conspecific karyotype data - for Asian barbets, owls and cormorants;
  • reorganization of genome through microchromosomes - avian karyotype, role in life history of birds with rise of sex chromosomes;
  • short genes, multigene families and isochores - average avian gene, smaller than the average mammalian gene
