As a result, it might have added new structures at the end of its fins. So once I got my hands on my genome I went to a number of scientists and asked them if they could help me make sense of it.

One of the main ways our picture has changed in recent years is the concept of epigenetics: What did you find out.

But when you intervene in a tiny clump of embryonic cells in a way that will pass down altered DNA to future generations, you need to think about what could be the broader effects. Consequently, Americans still debate what place human evolution has in the classroom.

The proteins made from the gene then grab other genes and switch them on. If you want to really see all your DNA down to the very last letter, you need to go to whole genome sequencing.

In fact, this is already happening. In the short term, that had a terrible social impact, because several scientists and politicians felt we knew enough to control heredity for the betterment of society: Imagine one man takes a cheek scraping, turns them into stem cells, turns some of those cells into sperm and eggs, fertilizes the eggs with the sperm, and that turns into an embryo.

As a fish embryo grows, it develops bumps on its sides. The endochondral bone expanded, and the fin rays shrank back, creating a new structure known as a lobe fin. So when I think about that possibility it just seems like we could really be going into a science fiction future.

The fins of bony fishes alive today—like salmon or goldfish—are still built according to the same basic recipe. As a fish embryo grows, it develops bumps on its sides.

The top figure here looks down at the back of the fish. Recently Renata Freitas of Universidad Pablo de Olavide in Spain and her colleagues set out to try to unlock that potential.

It could be dangerous though, because those genes might spread to a closely related species that you actually want to save, and nobody knows how easy it could be to pull back CRISPR once you release it into the wild like that.

But it still had fin rays forming fringe at the edges of its lobe fin. Scientists have found that many of the same genes switch on in the limb buds of tetrapod embryos.

The bottom figure provides a close-up view of a fin. Suddenly, we are on the precipice of a Brave New World. Instead, this experiment provides a clue and a surprise. In the developing fish fin, it produces proteins along the outer crest early on in its development.

The public policy that will determine what we teach our kids and how we deal with climate change will hinge on whether or not voters understand the scientific method, or at least value scientific evidence.

Carl Zimmer’s advice for aspiring science writers

This was the first time heredity went from being something I learned about in class to one of the most important things in my existence. It provides some strong evidence for one of the mutations that turned fins into tetrapod limbs.

What is your take on those connections. How close are we to that happening. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. It then shut off, as it does in fish.

However, when passive voice creeps into non-academic writing, it can leave the reader with the impression that phenomena unfolded without any apparent cause. Did you find anything in your genome that scared you.

Here, some scientists proposed, might be an important clue to how the hand evolved.

The risk could come when people read about the genetics of intelligence and say: After our ancestors split off from theirs, our fins became even more limb like.
