Earth wasn't always an oxygen-rich world. In fact, oxygen was once a deadly pollutant to much of the life that existed. Discover how tiny cyanobacteria transformed our planet through photosynthes...

An explosion appears to create chaos, but it doesn't. It follows the laws of physics and chemistry. Even in what looks like chaos, there is order. I don't understand how that could be. Makes...

DNA contains instructions for building proteins. Those instructions have a start signal and a stop signal. How can chemistry produce a code that knows exactly where to begin and where to end? I don&#0...

Romanesco broccoli grows in beautiful spirals. Those spirals follow a mathematical pattern. Why would a plant grow according to mathematical rules? I don't understand how that could be.<br /> #MakesYaT...

All life is made from atoms. Atoms that aren't alive. So how do billions of non-living atoms become alive? I don't understand how that could be. <br /> MakesYaThink.com<br /> MakesYaThink.com#MakesYaThi...

The universe may have begun with a giant expansion. It looks like chaos. Yet the laws of physics and chemistry were already at work. Where did those laws come from? MakesYaThink.com#MakesYaThink #Scie...

In Part 2, we explore Pelagibacter ubique, one of the simplest free-living organisms ever discovered, and examine Michael Behe's concept of irreducible complexity through the bacterial flagellum....

Scientists often describe microbes as "simple" life. But are they really?<br /> In this video, we explore the hidden microscopic world around us and ask a surprising question: How simple is simple...

How long is a billion years?<br /> Imagine Earth's 4.54-billion-year history compressed into a single day. Life appears around 4:00 a.m., dinosaurs around 11:00 p.m., and humans only in the final secon...

What is Life? (Part 2)<br /> If a machine could learn, repair itself, reproduce, evolve, and survive on its own... would it still be just a machine, or would it become a new form of life?<br /> This episode explo...

What is Life? (Part 1)<br /> What separates living things from nonliving matter? Scientists use eight key characteristics to define life—but some things, like viruses, don't fit neatly into either cate...

How did life actually begin?<br /> 4.5 billion years ago, Earth was a chemical soup. Gases and water reacted to form life's building blocks: amino acids, sugars, and lipids.<br /> But how did inanimate matte...

What was Earth like before life existed? Scientists believe it was a world of volcanoes, toxic gases, and violent storms—yet the same laws of chemistry and physics already governed everything. If thos...
