Listen to this TED talk. He is describing our bodies molecular functions in a way that shows how truly amazing toe bioengineering is:-https://youtu.be/EKopW86CCJo-At 4.5 minutes:-"Now what's most unsettling to me about this is that we didn't build these machines. As someone originally trained as an engineer, I've got to be honest with you, I kind of hate this. As the most clever species on the planet, we kind of like to think of ourselves as the builders of the most sophisticated technology in the entire universe. We invented written language and the printing press. We cured polio and sent a man to the moon. Heck, we even took savage beasts and turned them into kittens, and then built a global communications network to share pictures of them. That's pretty impressive.-"And yet when I look through a microscope at a humble bacterium -- by the way its ancestors were on the planet a billion years ago, billions of years ago -- I still wonder how it really works. Because the mechanical watch that is life is not like any watch we've ever built. It is biological gears and springs, but they fill rooms and buildings and cities of a vast microscope landscape that's bustling with activity.-"On the one hand it's extremely well organized, but on the other hand the sheer scale of all of this unfamiliar well-organized stuff that happens in there makes me feel that I've stumbled onto an alternate landscape of technology that's built by an engineer a million times smarter than me."
