Final answer:
Early trauma can cause long-term changes through epigenetics, altering gene expression without changing the DNA sequence itself, potentially affecting future generations.
Step-by-step explanation:
The statement is True: Early trauma and abuse can indeed have long-term consequences on an individual through the mechanism of epigenetics. Epigenetics refers to changes in gene expression that occur without altering the underlying DNA sequence. These modifications are influenced by environmental factors and can affect DNA organization. An example of this is observed in individuals who have experienced early trauma or smoking in childhood, which can result in various physical and psychological changes, such as stunted growth or increased susceptibility to certain disorders. Such epigenetic changes can be heritable and, therefore, affect not only the individuals directly exposed but also their offspring. The study of these changes is crucial as it offers insights into the potential long-term effects of our environment and behaviors on our health and that of future generations.
