Here's normal human DNA, and here's the DNA of the monsters we're fighting. My God! it's only [[You Fail Biology Forever|0.2% different!]] Despite the fact that the monsters have unexplainable powers, and look, act, and think almost nothing like us, there's no real difference between us and them! Really makes you think [[Humans Are
In [[Real Life]], it is true that we share some portion of our genome with many other species. Hell, humans have specific genes that are pretty much the exact same as ''plants''. According to most scientific theories, this is because all organisms are descended from the same progenitor organism species, which also used DNA, the universal genetic code. Some experts theorize that the first species may have used RNA, which was later used to code for DNA. The genes that were present in that original organism are still around, since they generally serve very important purposes in controlling different aspects of development, but those aspects that they control have been changed and co-opted into other pathways over time. So genes that function to pattern flower growth in some plants (determining which parts of a bud turn into petals, stamens, etc) are necessary for directing heart development in humans.
