They forgot to explain the imperfections and/or limitations of nature (cancer, shortcomings of the body, etc).In short, this is a documentary film that promotes ID (Intelligent Design).The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon.At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds.In some classifications, extant mammals are divided into two subclasses: the Prototheria, that is, the order Monotremata; and the Theria, or the infraclasses Metatheria and Eutheria.The marsupials constitute the crown group of the Metatheria, and include all living metatherians as well as many extinct ones; the placentals are the crown group of the Eutheria.They explain their science from their point of view and do not share the arguments for evolution.They explain how perfect and wonderful life is and that it could not come by chance.

The largest orders are the rodents, bats and Soricomorpha (shrews and allies).
The next three biggest orders, depending on the biological classification scheme used, are the Primates (apes and monkeys), the Cetartiodactyla (whales and even-toed ungulates), and the Carnivora (cats, dogs, seals, and allies).
While mammal classification at the family level has been relatively stable, several contending classifications regarding the higher levels—subclass, infraclass and order, especially of the marsupials—appear in contemporaneous literature.
Much of the changes reflect the advances of cladistic analysis and molecular genetics.They did this by not letting the public know their true intention.
