Scientists have made a breakthrough in epigenetics.
Epigenetics is the term given to information that has been passed down to us from our ancestors, but not in our DNA, in something deeper than that.
The study of our DNA has revealed many secrets of the human race. We have identified genes which make our hair curly, decide if we like the taste of a certain food or not, and even if we can curl our tongues.
But DNA also holds the clue to more in-depth knowledge of our species. We all have inbuilt fears, things we are attracted to and ways of acting that have been left over from thousands of years ago.
Physical violence is one of the hang-overs from millenia ago that rationally we have evolved past, but sometimes our animalistic instincts rise to the surface again.
In trying to figure out why some of our characteristics are so ingrained, scientists had to look past the simple DNA codes that we all carry in our cells, and they made a remarkable discovery.
In studying epigenetics, they found that stored deep in our psyche, even past where DNA reaches, are characteristics that had managed to be passed down through no less than fourteen generations. This means you might like a certain type of music, or prefer a certain climate because of the way your relatives lived 1000 years ago.
Scientists tested their theory on glow-worms, which were tested because of their ability to store heat and light, and their preferences are easy to decipher.
After being given choices of different temperatures to live in, the choices that they made were remembered by their offspring and was replicated down through 14 generations.
We can often attribute our characteristics to our parents, but there may be a part of you that has been left over from you ancestors who were alive millenia ago.
