Survival of the Sickest – Sharon Moalem

A fascinating book with an underlying theme of how evolution drives certain patterns that appear counter-intuitive at first glance; this book will make you rethink things you always knew to be true, and some you wished you had known before.


Each chapter can be read independently. Here is a sampler:

Bloodletting may be a cure: germs thrive on iron, and decreasing iron in the body helps fight the infection.

Fava beans damage red blood cells in people with a specific gene variant. This gene variant is common in several populations, but these same people cultivate Fava beans in the first place. The link? protection against malaria.

Epigenetics: It’s Nature and Nurture, apparently. to the extent that a pregnant woman on junk food can cause her grand-daughter to have higher risk of obesity and diabetes! Nutrition levels in the mother even at time of conception have a marked effect on the development of the baby.

A lot of our DNA actually comes from ancient (and recent) viruses. The good news is, at least some of this DNA is useful to humans.
