Epigenetics (by SciShow)
Hank & his clone Circus Hank explain the power of epigenetics, which studies the factors that determine how much or whether some genes are expressed in your body.
This is fascinating stuff - your behaviour, including what you eat, what you drink, how you exercise (or don't), your lifestyle, can change how your genes are expressed. And guess what? Your kids will have some of that passed on to them as well. Addicted to coffee? Your kids might end up the same way. Grandparents went from famine to feast? Guess what - it might explain why your kids are so fat on a regular diet. Epigenetics is rapidly changing the way scientists think about evolution even between just two to three generations.
