How social experience physically rewires the expression of your DNA
In short: Gender is more complex than just a set of chromosomes. This talk explores how life experiences—from diet to trauma—can permanently alter gene activity through epigenetics.
Biologist Karissa Sanbonmatsu examines the intersection of genetics and environment, specifically focusing on epigenetics. This field studies how external social factors do not change the DNA sequence itself but instead dictate how those genes are expressed.
By understanding these permanent changes in gene activity, we gain a deeper perspective on how our biology is shaped by our lived experiences, fundamentally shifting our comprehension of gender.
