I'm usually fine with Destin even though I know he's a very religious Christian, usually he can somehow separate the facts from his beliefs. If being a Christian is the best thing for him, more power to him. But he needs to keep it out of his science videos, as he has done a good job of in the past.
In this video he stepped over the line for me. This whole intelligent design thing has been a goal post moving operation for decades now. Every time scientists show how a complex thing evolved from an earlier thing, they move the goal posts and claim that previous thing is actually the thing their deity designed.
The records from millions of years ago may be incomplete, especially when it comes to things as small as this. So it could very well be the previous thing this evolved from isn't there to be found. That will open the door for Christians to say: "See! It hasn't evolved, it got put on the Earth by our God!".
I think I'm just disappointed in Destin I guess. He knew he was walking the line, which is why he added the part in the end. For me this was over the line, but that may just be my issue.
