Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate ...

Genetic information is stored in DNA as a sequence of specific base pairings. This is passed on largely unchanged from one generation to the next. But how is it possible that cells differ so massively in form and function, ...

Fathers are able to adjust to increasing temperatures within their own lifetime and do transmit this information to their offspring. This has now been shown for the first time in a wild animal. The findings were the result ...

In the version of evolutionary theory most of us are familiar with, randomly occurring variation in traits, caused by mutations in our DNA, can be fixed in a population through natural selection. However, writing in Epigenetics ...
