Twins [PDF]

by Lawrence Wright
The big take away from this book is that there have been many studies and mounds of data but not much has been resolved on the mysteries of twins. What correlates winds up challenged by the next study and politics hangs over this particular nature vs. nurture debate.

Wright presents many anecdotes (alludes to data that is not shown) of the twins raised apart. These point to genes as a determining factor in many things about their lives. Does this mean that all the efforts of parents, teachers and communities mean nothing? Is a life determined by genes?

Since this book is from 1998, I read it along with a well linked Wikipedia article. While there are now more tools for twin researchers, it's hard for the layman to spot what progress has been made. For instance, Wright states that it was not known when twinning actually occurs; the Wikipedia article, to a lay person, seems to give the how and when.

The most interesting part was the new to me concept of the vanishing twin. In 1998, the estimate was that 1 in 13 single births began as twins. The remains of the second embryo might be found in the placenta or as an implant in the surviving embryo or just disappear. According to Wikipedia, the number is now estimated as 1 in 8.

I would like to see an up to date edition of this book, with the actual data of the most significant studies.
