Welcome to the Eric Metaxis show with your host, Eric Mettaxas.

Hey there, folks. Some of you saw me recently talking about my book, Is Atheism Dead? I was on Tucker

Carlson's program. And on the program, I said that I had just been reading a book. I couldn't

remember the title. The title is Animal Algorithms. The subtitle is Evolution and the Mysterious Origin of

Ingenious Instincts. What I said on Tucker's program, which I'll repeat now, was that it's one of the

most amazing books I've ever read. And if you ever needed proof that there isn't the ghost of a chance

that all animal life evolved through random

mutations. This is, you know, front and center. It is truly one of the most amazing things I have

read. I said, wouldn't it be great to get the author on the program? And, you know,

whenever you want to get the author on the program, you're afraid somebody's going to say,

oh, I'm sorry, he passed away in 1946. That's not going to be possible. Well, in this case,

it's very possible. He's very much alive and well, and he is the author of Animal Algorithms and my guest today.

Eric, Castle, or is it Cassell? Welcome to the program.

Thanks, Eric. Yeah, it is Castle.

Castle. That's great to be with me.

Your book is a big deal, and anything published by Discovery I'm already excited about.

But what you talk about in this book, it's a little difficult for me to describe, so I'll let you take a crack at it first.

But before we get into what the book is about, what is your background?

If somebody says to you, other than writing this book,

what do you do? Because you have a kind of a complex history. Sure. I'm primarily an engineer.

That's my profession. But I have some other background that, at least I think in many ways, makes me qualified to write the book.

I also have a degree in biology, and I also have a master's degree in science and religion from Biola University, which was very instrumental in helping me to have the proper background to write this book.
