Examples
Pinpointing the exact timing of the rejuvenation event involved using so-called “epigenetic clocks.”
The clocks measure epigenetic changes, chemical tags on DNA that can accrue as cells age or are exposed to things like pollution.
For another, recent upgrades to CRISPR have made it possible to also turn genes on or off—without cutting them—through epigenetics.
It’s enormously powerful—because one single epigenetic machine can control hundreds or thousands of genes.
Prunicki’s group found epigenetic changes in four genes that regulate immunity.
Whereas some epigenetic changes are temporary, others can be permanent, and even passed on to the next generation.
Now he explains candidly that he has been driven to the view that epigenetic development does not exist.
I take up a more epigenetic position, and years ago I attacked evolutionary doctrines in many of their modifications.
Epigenetic: the period after the union of the male and female elements, during which organs are forming.
Digby thus makes a good statement of epigenetic development.
