Your Inner Fish
Chapter 3 Summary
In a nutshell, the Chapter 3 of Your Inner Fish explored what aspects of DNA impact development of organisms. The "inner fish" referenced in the title that Tabin's research ended up finding was not what he had previously expected during his initial experiments. He instead found that the "inner fish" lies in the biological tools that are responsible for the construction of fins. All appendages, regardless of what they are related to, are built by very similar types of genes.
What does this mean...?
This discovery that Tabin's research group found proved that the transition from fish fins to limbs didn't evolve the origin of new DNA, rather it involved the usage of ancient DNA.
What else...?
Tabin's research on flies and chickens also helped the world to gain a better understanding of human birth defects.
Connection to what we are doing...
Similar to the experiments that Tabin's posse performed, we are also messing with the development of bacteria. We are attempting to make our pGlo glow in the dark. By changing certain parts of the bacteria as it develops, we are hoping that the pGlo will glow after the changes have been made to it.
The experiments that we are performing are on a much smaller scale; (we are not giving chickens deformed wings or building backwards flies) however, the experiments are the same basic concept that Tabin's posse explored.

just for kicks...
