By DNA code, you may mean the genetic code - the translation of nucleotide triplet codons to amino acids. Or you may mean the DNA sequence in general.

Squids very clearly evolved within the cephalopods, and there is strong molecular and anatomical support for this. Squids did not evolve separately early on in the history of life.
