If speciation is true, for instance, then common ancestry must also be true.
What? Did he just say that if speciation is true then common ancestry is true? Seriously? If what we observe in nature (speciation) is true, then this far-fetched story that all organisms evolved magically from one organism billions of years ago must be true? Why? How have we come to that conclusion. Sorry, I must not have gotten as confused with all of the switch-a-roos as you meant for me to. And this guy is a science teacher?
