Examines how epigenetic modifications (chemical tags affecting gene expression without changing DNA) can be inherited across generations. Shows how parental experiences can modify offspring development - a form of ecological inheritance where parents 'prepare' offspring for environments they experienced.
Key Findings from Jablonka & Lamb (2015)
- Epigenetic modifications can persist across multiple generations
- Parental stress can induce inheritable changes in offspring phenotypes
- Epigenetic inheritance represents a mechanism for transmitting environmental information
