The Hoatzin have some primitive characters together with some
specializzation (I don't know this because the text do not cited) and it is
not a good flighting bird because it has a short sternal carina and have a
pectoral muscle not well developed. For me Hoatzin is the best example for
understanding the life style of Archaeopteryx.
