The Transformers SCORE, not soundtrack...

... is excellent. I couldn't give a rat's ass about all the different music by whoever artists, but Steve Jablonsky's score is most excellent.

Hypotheses Biological

I hypothesize that a certain degree of development is random. Penetrance accounts for the fact that identical genetic information between a plural will often result in different phenotypes. If this is so, then the only way to get 'desired' characteristics is to repeatedly express the same template in multiple subjects, separating those that are desired.

I also hypothesize that the cure to cancer is within the body itself. I take for example, the repair of thymine dimer mutations within DNA.
From Wikipedia: " Excision repair enzymes and the DNA repair system can often recognize and repair this type of damage by the large kink in the DNA that it causes. In many organisms (excluding placental mammals such as humans), DNA photolyases can repair the damage directly by cleaving the dimer.
Unrepaired or mis-repaired thymine dimers and the resultant mutations can contribute to the development of skin cancers."

The body does it itself. As such mutations can cause cancer, then hypothetically, the cure for cancer can be found within the body itself. If something is not right, the body's own machinery must be able to fix it. If not, I am 100% positive that enzymes can be engineered to hunt down specific mutations to correct. However, as there are many types of mutations, it will conceivably take a while to find ways, enzymatic or otherwise, to fix the different mutations in DNA. However, as oncogenes are often, if not always, the epicenter from which cancer begins, those are the points where we need to be looking.
