Suppose I take a group of alligators select the ones that emit the highest frequency of radiation (since all living creatures emit thermal radiation), and I breed those, and get rid of the rest and continue this for thousands of generations. Is it possible, that at one point the frequency of that radiation becomes high enough to enter the visible light spectrum?
My theory is that, since the criteria we have selected for the selective breeding is high frequency radiation, a point should come where the radiation becomes high enough for us to see, because after all, it is the body that is creating the energy, which depends on the genes of the alligators.
And if it is possible, could we exceed the visible light spectrum? Maybe reach a point where the alligators start emitting X-Rays or Gamma Rays? And do you think the alligators, as creatures, would completely change in order to keep up with the selective breeding system?
After seeing the answer's I've got, I remembered that alligators are cold-blooded, so would this work for warm blooded animals like monkeys, or any animal if possible?
