EPIGENETICS: How Environment Affects Your Genes

Have you ever wondered why twins, even though they have EXACTLY the same DNA, end up being so different? Not only personality-wise, they can also end up having completely different health conditions. Genes define us. They do, but to a certain extent. Behavior and environment also play a role in our development. And they can do so by causing genetic changes. But here's the thing: this does not necessarily involve any change in the DNA, but rather the way our body reads it. The study of these reversible changes is what we call epigenetics. Our lifestyle can trigger certain epigenetic changes. Some lifestyle factors linked to epigenetics include diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts. So, if a person's experiences can have an impact on their genome through epigenetics, does this mean it can all, somehow, be passed down to the offspring? Well, not really. Although epigenetic changes can indeed be inherited. But it's not that simple. 00:00 Genes vs. environment 00:55 Twins.
