DNA Art, from Farscape to Reality

A way back, in 1999, the SyFy channel (then called SciFi) show Farscape featured an episode in which the mad genius Nam Tar offered to take DNA samples form our fugitive crew and use it to provide a roadmap back to each of their home planets.  Ostensibly, NamTar could trace the mutations in their DNA back to their planetary origins, and, using that data, provide a road map back to their home planets.

This was one of those times when a science fiction show’s writers had less imagination than reality: Not only can we use DNA to trace back to our origins (though only locally, on this planet); we make art out of it.

I heard about artist Lynn Fellman at a talk by Ira Flatow, of Science Friday fame: Working with the University of Minnesota’s Urban Outreach/Engagement Center, Fellman sent DNA samples from seven north Minneapolis residents to The Genographic Project, which specializes in population genetics. The lab analyzed mutations in the DNA to provide an ancestral path for each resident from present day Minneapolis down through pre-history to humanity’s origins in Africa. Fellman turned these maps into art for UROC’s Deep Ancestry exhibit.

The science is fairly straightforward. Neither the Y-chromosome nor mitochondrial DNA recombine during reproduction, meaning DNA from either forms a long unbroken link back to our most distant ancestors. Since fathers pass the Y-chromosome to sons, we can use it to trace our patrilineal heritage. Mothers pass down our mitochondrial DNA (as everyone who hung on for the finale ofknows) so it can be used to follow our matrilineal ancestry.

Though these molecules don’t recombine, they do change, over the millennia by random mutations. A single mutation will eventually spread through a population living in a particular geographic area, forming a haplogroup. Each mutation-defined group can be pinned to a specific time and place. By following the mutations, geneticists can trace our ancestry through space and time.

NamTar, in the show, used that information to draw a map through the galaxy. Fellman uses it for mapping as well: Her art begins with a portrait of the person, and then traces their ancestry along their haplogroups back to our origins. Art imitating life that imitated art.

  1. Hi Eric, you should check out DNA 11’s new DNA Ancestry Portraits.

    DNA 11 is the original DNA art company and the DNA Ancestry Portrait is the next step in our product line that encodes your personal mtDNA ancestry into a 2d barcode that when scanned with a smartphone brings you to a personal ancestry page.

    Contact me if you’d like some more details.

    how would you be able to use DNA to trace a path back to somebody’s home planet? That seems to rely more on the audience’s misunderstanding of how DNA works than any real science.
