This film dealt with similarities between manatees (a species of plant-eating aquatic mammal found in tropical Atlantic coastal waters) and elephants, and suggested these had evolved from a common ancestor.
However, this claim has no scientific basis to it, and consists of speculation based on evolutionist preconceptions.
Both creatures are placed by evolutionists within the super order Afrotheria. This super order was established as genetic analyses have gained pace in recent years. In other words, the idea of an evolutionary relationship portrayed on the National Geographic TV screen consists of an interpretation of the DNA data of these two creatures from an evolutionist perspective.
Afrotheria is rather peculiar in terms of the alleged evolutionary relatives it harbours. Elephants and manatees are regarded as relatives within this super order, although the habitat and lifestyle of the manatee is totally different to those of the elephant. Elephants live on land, and manatees in the sea. There is also no similarity, beyond the basic mammalian design, between their anatomies. Another animal in this super order portrayed as a relative of both species is the pygmy shrew, which plays a role that further increases the odd nature of the super order Afrotheria. The forced nature of these claims can be clearly seen from the debates taking place among evolutionist circles.
Anatomist evolutionists have not remained silent in the face of such anatomically different animals being classified in the same superorder, and there have been frequent strong debates between evolutionists who rely on DNA and molecular similarities and those relying on anatomical ones. Each group of evolutionist researchers holds views that are the exact opposite of those of the other.

The claim that the elephant and manatee are related, which is being rocked between evolutionists’ conflicting theories, vanishes entirely when one looks at the fossil record. That is because in the fossil strata all mammalian groups emerge suddenly, and with perfect physical structures. This is a sign that there is not a trace of the many intermediate forms one would expect to find in the light of the blood links alleged by evolutionists to exist between animals living in such different habitats as the elephant and the manatee, in other words, evidence that the story of an evolutionary link between the two is totally unrealistic.
