Its demesne is Animalia, Phylum: Chordata, class: mammalia, fix up; Cetacea, Family; Balaenopteridae, Genus; Megapt date of reference, Species; Novaeangliae. The evolution of the hunt downs is controversial due to it macrocosm hard to stick a fossil. Scientist debate that the earliest forms of cetaceous were originated in the Eocene era (about fifty one million million classs ago). The sub give archaeoceti could be instal in tropical botany in and close to swamp lands and move on seas (Evans 1987). According to Evans the archaeoceti were aquatic elongated species and trim down hind limbs. They were n previous(predicate) adapted to biography along the soaring and the open sea. As the Cetacean order moved into the ocean, they began to fail certain traits to help oneself them to survive.
