Marco Rubio, the U.S. Senator from Florida, who is such a success story, (his father having immigrated from Cuba. I can still remember Rubio speaking at the Republican Convention saying "these United States" OK I didn't think he was talking about any other United States, but go on.) Anyway Rubio was recently asked "How old is the earth?" And because he did not immediately say 4 billion years the combined weight of 25 years of television science journalism immediately came down upon him and he was flattened like a pancake. And I am sure the interviewer smiled in his heart of hearts and said "Gotcha".
The design view predicts that there will be great similarity of genetic code between species just like there is great similarity of code between any two iPhone apps because the apps all contain many of the same code objects to handle the routine tasks of any program. Therefore, the similarity of the genome between species is probably not evidence for evolution or common descent, but rather it is probably evidence of a style of programming we use ourselves; object oriented programming, and that's evidence for intelligent design.
