Twins: An Investigation into the Strange Coincidences in the Lives of Separated Twins by Peter Watson

Stars: ****

This is one of the best books on Twins and the similarities and differences between them and whether they are from nature or nurture. The only reason I did not rate the book 5 stars is because a few chapters are long and monotonous and I lost interest in them and because is keeps switching between the terms identical and fraternal and MZ (monozygotic) and DZ (dizogotic). The book should use either the first two OR the second two, not keep switching. Also it doesn’t explain the heritability scores very well and I found them confusing. If you are not into the nature-nurture debate, you can just read the sections on the similarities between the separated at or near birth twins.
