In the final part of the documentary, it is claimed that the sponge is the ancestor of all animals. This claim rests on a comparison of certain fundamental areas in the DNA sequences in living species with the same areas in the sponge DNA chain. In this way, the finding of similar DNA sequences is regarded as evidence of ancestral relationship by evolutionists.
The fact is, however, that this logic is invalid. DNA is a common language by which life is described. If we think of DNA as sentences which describe how a cell works, DNA consists of different sentences in which different words are used. The fact that the same words are encountered is the inevitable result of the fact that this coded language employs only four letters. To put it another way, the finding of similarities in DNA does not in any way show that living things had a common ancestor. This similarity is proof not of a "common ancestor," but of "common design." Every similarity we encounter proves the common aspect of the design in living things.
On the other hand, just the length of the DNA in the sponge is sufficient to invalidate the evolutionists' expectations. The DNA of the sponge, put forward as the "primal animal ancestor," consists of 1.8 billion base pairs (1.80pg.) According to the evolutionary family tree, the DNA of the tench (species Tinca tinca) should be a great deal longer than this, whereas in fact it is only half the length of sponge DNA, consisting of a mere 810 million base pairs (0.81pg.) The chicken, described as a much more advanced species than the sponge in the evolutionary family tree, also has DNA that is shorter, at 1.25 billion base pairs (1.25pg.)
As we have seen, the genetic facts are at total variance with the assumptions of the theory of evolution. As the scientific findings have shown, living species did not evolve from one another, but were created separately.
