Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.

Time flies when you're learning super cool stuff. I'm Nate.

And I'm Callie. If you're dropping

in for the first time welcome to curiosity where we aim to blow your mind by

helping you to grow your mind. If you're a loyal listener, welcome back. Today you'll learn about a compelling study on twins and the nature versus nurture debate,

how scientists solved a 60-year-old mystery about bees, and why you shouldn't go last.

Without further I do, let's satisfy some curiosity.

Twin brothers, Dennis, and Douglas were inseparable when they were young,

and they were so hard to tell a part that most people could only tell the difference between them because they drove different

cars. But something happened when they were in high school that would see their paths sort of diverge.

Dennis suffered a traumatic event when he was 13.

But Douglas didn't experience the trauma?

No.

Okay, so this has to be a nature versus nurture story, right?

Because if these siblings are genetically the same, then certain differences that come up in their lives could be the result of life events rather than biology or genetics.

That's exactly right. And while Douglas led a stable family oriented life Dennis faced a lot of

emotional struggles and turmoil throughout his adulthood and it's examples like

this one that have motivated lots of researchers to conduct studies on twins.

Sure, I mean it seems like every couple of years the attitude over nature versus

nurture go back and forth.

One study shows that our behavior is basically predetermined by our genes.

And then another comes along and says it's all about what happens to us that determines our lives.
