DNA – highly functional or mostly junk? Part 1

---

Is the human genome highly functional or mostly junk? This is a question that is not only being asked in the creation-evolution debate; it is a question raging in the ivory tower as well. The ‘old guard’ is much more likely to resist any claim that large swaths of the genome are useful. The ‘young punks’ in science is more willing to accept the obvious fact that the genome is highly functional. Who is going to win? In this episode, Dr Carter highlights four new studies that ratchet the argument toward high function.
