whatlani said: Hi! my name is Lani! I just read Survival of the Sickest by Sharon Moalem, and I saw from a long time ago that you read this book as well. For my AP biology class at school I have to now write a position paper about the biological issue presented in the book. I know the issue would be evolution but do you have any ideas as to the good and bad sides of that? or do you think would there be another biological issue in the book? thanks in advance -Lani
It has been quite some time since I read Survival of the Sickest, so I cannot remember it entirely in details. But one of the major biological issues I see, is that we humans are seeing all our evolutionary adaptions that made us who we are today as diseases. If you can remember the first chapter about hemachromatosis (“Ironing It Out”), it states that some bacteria feeds on iron and can have excessive growth, which is why Yersinia pestis would hit hardest on the healthy adult men, and less hard on the children and the elderly (who often were malnourished) as well as adult women (who were iron depleted after child birth etc.). The iron is distributed almost equally throughout the body’s cells in healthy adult men (and women), but with hemachromatosis it is different. Even though there is excess iron in most cells, macrophages have less iron than normal. This gave people with hemachromatosis an advantage against i.e. the bubonic plague. But today it is a huge disadvantage and seen as a disease.
Another approach could be how these adaptations still are common today and if they can be used as a treatment for people with other diseases. For example with stem cell therapy and genes from someone with an adaptation., if you follow my lead?
I hope this could be of use for you.

Sex should be fun, happy, and enjoyable AND HILARIOUS… I mean, that’s my personal opinion/philosophy, but it’s served me well through the years. :)
Truer words has never been spoken.
