What gets really interesting is if a whole new alphabet and a whole new language suddenly appears. That would be the equivalent of speciation.

Sorry, I don't see what you're getting at. In genetics there are only four "letters" in the alphabet and the alphabet never changes. Both variation within a species and variation between species are nothing more than variations in the pattern of those four letters.

Unfortunately, so far, we have not yet identified a single gene that causes/results in speciation.

Just looking at some stuff the other day on insertion of mammalian nucliae into other mammalian eggs, depending on the species of the egg (e.g. from a mouse, from a human, from a cow) different genes are turned on at different stages in the nucleus, and that can make all the difference in development past a certain number of cells.

The researchers found you can't just take a human nucleus and stick it in a mouse egg. Doesn't work.

They reported that thousands of other things don't work either.

I suspect they are on the track of where the information rests that differentiates species, and that it's not in the nucleus, or in the various vacuoles and inclusions inside the cell membrane, but in the centriole which connects the nucleus to the cell membrane, or maybe even in the cell membrane.

That's probably where some pretty powerful biological data processors are maintained as well.
