<prompt> Hlalosa hore na ke hobaneng ha maruarua le li-dolphin e le tsa odara ea Cetartiodactylanan  <response>: Instruction in English: Explain why whales and dolphins belong to the order Cetartiodactyla . Response in English: Whales and dolphins belong to the order Cetartiodactyla because this order includes two groups: the cetaceans, which consists of whales, dolphins, and porpoises; and the artiodactyls, which contains even-toed ungulates such as cows, pigs, and sheep. Cetartiodactyla is an order in the class Mammalia, and is commonly known as the even-toed ungulates.The grouping of cetaceans and artiodactyls in the same order is supported by molecular evidence, which has shown that whales and dolphins are more closely related to even-toed ungulates than they are to other marine mammals such as seals or sea lions. This evidence has also shown that the common ancestor of whales and even-toed ungulates lived about 50 million years ago, and that whales evolved from land-living mammals that gradually adapted to life in the water.So, whales and dolphins belong to the order Cetartiodactyla because that order combines the cetaceans and the artiodactyls, and molecular evidence has shown that whales and dolphins are closely related to even-toed ungulates. . Response in Sesotho: Li-whale le li-dolphin ke tsa taelo ea Cetartiodactyla hobane taelo ena e kenyelletsa lihlopha tse peli: li-cetaceans, tse nang le maruarua, li-dolphin le li-porpoise; le li-artiodactyls, tse nang le likokoana-hloko tse sa tšoaneng tse kang likhomo, likolobe le linku. Cetartiodactyla ke taelo ea sehlopha sa Mammalia, me hangata e tsejoa e le li-ungulates tse lekanang le menoana. Ho hlophisoa ha li-cetaceans le li-artiodactyls ka tatellano e tšoanang ho tšehetsoa ke bopaki ba limolekhule, bo bontšitseng hore maruarua le li-dolphin li amana haufi-ufi le li-ungulate tse nang le menoana ho feta ho liphoofolo tse ling tse anyesang tse kang liqibi kapa litau tsa leoatle. Bopaki bona bo boetse bo bontšitse hore moholo-holo ea tloaelehileng oa maruarua le li-ungulates tse nang le menoana e lekanang li phetse lilemong tse ka bang limilione tse 50 tse fetileng, le hore maruarua a bile teng ho tsoa ho liphoofolo tse phelang fatše tse ileng tsa ikamahanya le bophelo ka metsing. Kahoo, maruarua le li-dolphin ke tsa taelo ea Cetartiodactyla hobane taelo eo e kopanya cetaceans le artiodactyls, me bopaki ba limolekhule bo bontšitse hore maruarua le li-dolphin li amana haufi-ufi le li-ungulate tse nang le menoana ea maoto.
