WHY WE EAT CORN TODAY
Many grocery items contain corn, which provides 20% of a person's daily nutrition. Corn has come a long way in order to be accepted as a legitimate food, and there are many reasons why it never should have been one of the plants we domesticated for consumption.

THE ROCKET OF THE FIRST ORDER
While different rockets look alike, all have a cone-shaped nose at the top and a big tube holding fuel and the rest of the propulsion system underneath. However, you don't need to set your rocket up that way to fly. We know this because the first modern one looked very different. %in 1926, a rocket called Nell blasted off from a Massachusetts farm%. While it wasn't bound for space, it introduced many of the fundamentals of rocket science that would ultimately get us into orbit and beyond. Nell was by no means the first rocket to ever launch.

THINGS TO KNOW ABOUT THE GIANT CREATURES THAT EXISTED
I'm going to share with you some of the largest and most impressive animals that have ever lived on Earth. The Argentinosaurus was one of these creatures, and scientists believe it was one of the largest land animals in existence. It had a length of up to 100 feet and a weight of up to 100 tons. This giant leg bone was found by a farmer while tending his cattle, and this is how the first fossils of the Argentinosaurus were discovered.

ROOTS: THE AGENT OF CHANGE IN GLOBAL WARMING
Planet Earth is losing its roots. Plant ecosystems are so large and complex that their roots are effectively global. They shape the planet and hold it in place against change. And when we grow plants for agriculture, we change root systems which means that in the unavoidable act of growing food, we’re losing a tool that helps us resist the effects of the climate crisis.

THE TEETH: NOT AS WE KNOW THEM
The teeth we have today weren't always like this. In the fossil record, ancient humans usually had straight teeth complete with third molars or wisdom teeth. And, according to recent research, dental dilemmas that fuel the demand for braces and wisdom teeth extractions today appeared to be recent developments. So what happened? While it's nearly impossible to know for sure, scientists have a hypothesis. A couple million years ago, the ancestors of modern humans lived a subsistence lifestyle. Their teeth and jaws had to work hard to make the food they ate digestible. Indeed, many of their teeth showed extensive wear and flattening. They also had larger jaws and teeth overall.
