From Walter Myers III at ENST:
While much of the DNA code may be the same, the parts that are not the same have significant differences. The programs I described above, such as Facebook, Instagram, or Snapchat, have different purposes, yet they all depend on the same OS that consists of tens of millions of lines of code. To be specific, let’s say you are using an iPhone with iOS 11 (the Apple mobile OS) installed. iOS is estimated to take up about 4 GB of space on your iPhone. Facebook takes up about 297 MB. Snapchat is about 137 MB. Instagram is about 85 MB. Respectively, that’s 7.4 percent, 3.4 percent, and 2.1 percent of the size of iOS. Now would anyone say that Facebook, Instagram, and Snapchat are pretty much the same thing since they are each well over 90 percent the same? Of course not. It’s not so different with humans and chimps. In the case of these programs, the vast majority of their total code base is shared, yet each is a distinct creative expression that leverages a shared base of code. In the case of humans and chimps, one would expect a designer to use shared code where functions are the same, and different (new) code where functions are different. When we examine computer programs, which are the inventions of human minds, why would they not reflect the mind of the designer that wrote the code to produce humans, chimps, and every other biological organism? More.
How many people would accept the current, crazy human-chimp similarity claims if anything important to them were at stake? How about this: You are counseling a difficult, disturbed teen and she thinks she can advance an animal rights cause by getting pregnant by a chimpanzee? Of course, her actions would never result in a live birth but what would you say to her?
