Epigenetic inheritance is not new.
It was well characterised when I was a student of biochemistry in the early 70s.
The modern evolutionary synthesis is not a simple thing.
Evolution is a recursive process.
Every new level of cooperation that evolves allows new levels of complexity to emerge.
At the base of all of these systems is genetic replication, variation, and differential survival in different contexts.
And modifiers can emerge.
At the molecular level there can emerge factors that chemically bind to the chromosomes and affect gene expression via circuitous pathways that include the replication of that blocking activity.
Similar things can happen at other levels of process, involving other sorts of chemical modulators of activity.
It gets really complex, really quickly.
Many orders of magnitude more complex than an operating system like Windows (and who knows how that works in detail).
Science is always complex.
People always have to have simple models of that complexity, because the reality is always more complex than any mind can hold.
The problem is, that most people don’t know that their experience and knowledge is necessarily a gross simplification of the reality present, they think their experiences are reality.
We are really complex.
Reality is many orders of magnitude more complex than we can possibly understand or model accurately.
We must simplify.
Sometimes those simplifications work to very high degrees of accuracy, and sometimes they fail in ways we are completely blind to.
That is what it is to be a human being!
