The Fate of Genes Is Not Destiny

Sharon Moalem dismantles the myth of genetic determinism with a single, uncomfortable fact: identical twins sharing letter-for-letter DNA don't share identical fates. The twenty-year hunt for a "depression gene" ended empty-handed, its early headlines exposed as statistical noise from undersized samples. What replaced it was epigenetics: the mechanism that decides which genetic chapters stay open or closed, the same system that turns genetically identical bee larvae into either sterile workers or hive-founding queens.

You'll learn:

- Why heritability measures populations, not individual destiny

- How lived experience rewrites which genes get read

- What the hundred-point genome scan actually proved
