I gemelli identici non sono affatto identici e i nostri geni non determinano affatto il nostro destino. È il messaggio centrale di questo libro, frutto del più grande studio sui gemelli che sia mai stato fatto e che Tim Spector conduce in Gran Bretagna da oltre vent’anni e dal quale è nata un nuova disciplina, l’«epigenetica», che sta rivoluzionando quello che sappiamo sui geni e sull’eredità biologica, aprendo campi di ricerca che erano considerati tabù solo pochi anni fa. Lo studio dei gemelli ha infatti convinto Tim Spector che la cosa più interessante sono le differenze, non le somiglianze, e che queste differenze sono il risultato di un dialogo continuo tra ambiente e DNA, in parte ereditabile. Ciò che fino a poco tempo fa la biologia considerava anatema, oggi non lo è più: i nostri comportamenti e le nostre esperienze modificano il nostro patrimonio genetico e sono in parte ereditati dai nostri figli e dai nostri nipoti. Che si tratti di credenze religiose, di orientamento sessuale, di predisposizione al cancro o all’obesità, i racconti dei gemelli di Spector confermano che, accanto ai geni, un ruolo determinante ce l’hanno anche le nostre azioni.

I wasn't sure how this would turn out, since it mentions the widely ridiculed Lamarckian theory of inheritance, and the subtitle "Why You Can Change Your Genes" might sound a tad self-helpy. Luckily, it is actually a sound examination of current epigenetic theory, based on MZ and DZ twin studies loo Leggi tutto
Tim Spector is a UK scientist who studies twins, particularly to explore what traits are inherited and which are not. He uses this as an entree into the field of epigenetics, which looks at how environmental and other influences change the way a genome functions without actually changing or mutating Leggi tutto
I appreciated this book for the data, but found many of Tim Spector's social ideas to be outdated, and some of his medical knowledge to be off. For example, he wonders about the "G-spot" and if all women have it. The G-spot is a part of the clitoris so yes, all those who have a clitoris have it. He a Leggi tutto
Best pop-science book I've read in ages. Cutting edge research presented in a witty and accessible way. Has genuinely changed the way I think about life, inheritance and evolution. Can't recommend it enough.
An interesting book on how our genes aren't as fixed as scientists have long thought they were. Interesting, but not as much as his other book "The Diet Myth". Recommended for the scientifically minded.
"Essentially, epigenetics is the mechanism by which environmental changes alter the behaviour of our genes," he says. "This involves a process known as methylation, which occurs when a chemical known as methyl, which floats around the inside of our cells, attaches itself to our DNA. When it does so, Leggi tutto
This was an annoying book to read. The author has no talent for writing and constantly says silly or stupid things. It's like his brain doesn't have a filter on it, and he talks like a hyperactive 6 year old. On page 70 he says: "a wave of best selling books... have all provided the same clear message" Leggi tutto
I read this after quite a few other of the books that Tim Spector refers too and coincidentally while on holiday with friends who have non-identical twins. I learned a lot that was new to me namely epigenetics which helped me make more sense of what is apparent but anecdotal about my own life experi Leggi tutto
A gene for this, a gene for that, add in a whole stack of twins, with epigenetics playing peek-a-boo..... and you have a rather dull book. This book might be more interesting if you aren't familiar with genetics, but if you are, then there is nothing new here. If you are looking for a more detailed
The conclusion of every chapter (whether he was looking at sport or religion) is the same - your phenotype is influenced by both nature and nurture. Isn't that what we've always known? There were no revolutionary findings, and I got bored of this book towards the end and didn't finish it.
