This example demonstrates epigenesis, which refers to changes in gene expression that are caused by environmental factors such as stress. The stress experienced by the young rats altered the development of the hippocampus, which is a brain region involved in regulating stress responses. This alteration was likely caused by epigenetic changes to the genes involved in hippocampal development, rather than changes in the DNA sequence itself.
