First off, what is a Mosaic? Is there really such a thing?

Certainly.

Mosaics have different cell lines within their bodies. But they’re born from the same egg.

Chimeras also have different cell lines. But they come from separate eggs.

Typically, when two eggs in the womb get fertilized by two different sperm cells, they create fraternal twins. But rarely, though it does happen, as the eggs begin their development, they fuse.

The title “Chimera” is mythical being composed of more than one animal. A human Chimera is someone with two sets of DNA. I find this fascinating because Mosaics and Chimeras live amongst us.

I read this interesting article about Mrs. “McK”. A woman in Northern England who donated blood in 1953 and it was discovered she two different types of blood. It was the first documented case of a human chimera.

Mosaics and Chimeras are all around. Sometimes they have two different color eyes. Sometimes they have different patches of skin. Mostly, the outward changes are subtle. They just have complicated DNA.

This kind of color in our own selves can be a great way to add depth to a character.

It can also make for good crime scene confusion. DNA analysis can distinguish a Mosaic’s sample from others. But a Chimera could be confused with another family member – unless the DNA is taken from the suspects blood.

But I really enjoy learning about what makes us ‘us’. Mosaicism and Chimerism are just another component of the most complicated animal on earth. The next time you need a good or bad character with two different color eyes, make them a Mosaic or Chimera. They might just get away with murder.

I just dig stories like this. For writers it can sound a little cliche. The northern ice melts, something scary is uncovered and suddenly there’s a problem.
But what I like about this story is that it’s real. Ancient infant remains found at a particularly well preserved burial site. Here’s where the writer in me comes out. What if the discovery also found an ancient relic or object that seems out of place or out of time? As if its symbol was tied to another culture on the other side of the planet and only showed up in history some several thousand years later?
What if we were able to extract DNA from this innocent child to find some new discovery in ourselves? What if it unleashed a terrible virus and no one in our time had immunity?
I know, this is not some super original idea. But I have this habit of having to tie everything back to something that actually could happen. I have always been a big fan of sci-fi and fantasy, but these days I need something a little more real. I need discoveries like this to keep it honest.
And who knows? Maybe the scientists did uncover something out of the ordinary and haven’t told us about it. Perhaps they’re already in the adventure of a lifetime. The Ancient Alaskan…
