Its state is Animalia, Phylum: Chordata, class: mammalia, lay; Cetacea, Family; Balaenopteridae, Genus; Megapt era, Species; Novaeangliae. The evolution of the titans is polemical due to it universe hard to disclose a fossil. Scientist look at that the earliest forms of electric fan were originated in the Eocene era (about fifty one million million familys ago). The sub assemble archaeoceti could be institute in tropical plant support in and virtually swamp lands and forward seas (Evans 1987). According to Evans the archaeoceti were aquatic elongated species and cut hind limbs. They were intimately adapted to life along the edge and the open sea. As the Cetacean order moved into the ocean, they began to perplex certain traits to overhaul them to survive. The Balaenopteridae, which the crookback is a member of, crapper be found as earliest on as Micene (five to fifty- millions year ag o). There was an past rorqual from this metre period called genus Megaptera miocene, which is similar to todays kyphosis whales, showing that humpbacks probably evolved and appeargond around the new Miocene era early Pliocene, and have existed eer since. The humpback whale has been hunted since its cr eat upion, making it endangered. In the eighteen hundreds the value of those whales change magnitude making them a perfect rump for hunters. With advancing implements of war by the xix hundred the whale state see a extensive decline of whales, thusly in the ordinal century the population went as mild as seven-hundred in north the States by cardinal sixty-six ecumenical only near five-thousand whales, making them endangered.
