First of all, I wouldn't believe ANYTHING Fox News says. They're the "News" of that Religious, "Creationist" sect of Politics. They tend to twist the truth pretty frequently.
Second of all, That depends on what reptile their referring to and the condition, it's in. (I didn't see it on the page. I'm guessing it's either not working or they're making it up.)
As for the possibility of any two headed animal, yes, that is possible. Ever heard of conjoined twins? I assume that the zygote didn't completely separate and only the head became two on one body.
Hope this helps!
