Thanks for the news friends!

Main discoveries:
 * Species C probably had 40 chromosome pairs (~30 microchromosomes)
 * The structure of chromosomes 5 and 11 are identical in species C and chicken.
 * Chicken has fewer chromosome inversions compared to species C than Ostrich.
 * Ostrich is the only ratite they used. A previous paper (user only chromosome paint, though) showed that in ratites emu and rhea chromos 1-5 were identical in structure with species C; while ostrich had much inversions in chromo 1.
 * chicken has no fusions between microchromosomes and chromosomes.
 * Microchromosomes are probably very conserved in birds.

This study has also shown that we need the genome of a non-avian archosaur. They used Anolis as an outgroup in this study. However, Anolis is too distantly related to birds. It has no chromosomes that resemble bird chromosomes 6-28 or Z. I would recomment a turtle, since (contrary to crocodilians) has microchromosomes and a Z chromosome.
