epigenetics is the ability to make identical cells present distinct phenotipic states.
Why?
DNA is packaged by charged histone proteins, and they wrap around the nucleosome. Upon acute changes in the environment, cells can change their epigenic states.
whimsical adaptations
Epigenetic adaptive states in organisms with no clear path adaptation. For instance, a certain lung cancer cell has this ability. So, how do cells decide what genes they would activate?
Another example: treating fisheries in caffine
- Growing in caffine will trigger caffine resistance
- Remove the caffine would cause some of them to default back, some of them to stay the same way
