Probably more recently than you realize!
Many of us have come to believe that our genes are an immutable endowment which underpins our health – for good or bad – but this may not be the case. Our genome may be only a starting point which environmental factors continually modify, with surprisingly rapid effect. And the role which these environmentally-induced changes play in disease may be as important as the genetic blueprint which they modify.
Not only might our genes change more often than we thought, but we may have far greater control over them than we imagined possible. And those of us who are hosting helminths may perhaps be having our genes changed for us – for the better – by our ‘old friends’.
