Genes are not the only things that are passed on from generation to generation.
Although genes take much time and several generations to change, the epigenome can change throughout a person’s life, and the changes can be passed on from generation to generation.
It’s proven that the grandchildren of men who experienced a famine during late childhood live longer.
Identical twins with the exactly same genes can be very different.
Genes can be turned on and off. Epigenetic changes are tiny chemical tags that accumulate over time and can turn genes on or off.
We have different kinds of cells because different genes are turned on to make them different.
Identical twins with the exactly same genes can be very different.
Cancer and some other diseases were thought to be caused by changes in the genome, but they can be caused by changes of the epigenome and/or changes of the genome.
Cancer tends to appear in people that smoke, that have certain environmental exposures or that are exposed to radiation. These things can damage your epigenome and your genome.
Cancer is more abundant with older age groups because epigenetic changes accumulate with age.
