Someone help me out here but I suspect there are certain genetic characteristics that are common to all lifeforms.

Yes, there are genetic characteristics common to “most” lifeforms. Almost all air breathers have hemoglobin to bind oxygen in their blood. The difference or similarity of each species hemoglobin is thought to be a reflection of their common ancestry, with species closely related having identical or similar hemoglobin, and diverse species having differences at the DNA level that do not translate to any difference at all in protein structure (the DNA code being redundant) or the changes are in regions that are not highly conserved between species and are mostly conservative substitutions (a polar amino acid for a different polar amino acid for example).

There are, we share something like 97% dna to rats. The thing is the cro-magnoids are genetically the same as humans. Neanderthals are not the same species as humans. Much like the difference in chimpanzees and apes I guess.

Yes. There is a 95% similarity between human and chimpanzee DNA.
