The Origin of Life | Theory of Chemical Evolution | Part 2 | Bio 101 | STEMstream

The question of how life began on Earth is considered to be the "mother of all questions" amongst not only scientists, but anyone with a curious mind who loves to venture out into the unknown and ponder life's wildest puzzles and uncertainties.

This video goes in depth into the science behind the most widely recognized and accepted scientific theory for life's origin on Earth: Chemical Evolution. For introductory biology students and anyone who loves a good science review, this video series is a must.

Part 2 ends the discussion on the incredible properties of water with its ability to absorb large amounts of energy and its important function in acid-base reactions in our body to maintain homeostasis. We then transition into the most important chemical reactions of chemical evolution, and conclude with discussing carbon, the most versatile and abundant element in all living organisms on Earth. We hope you enjoy!

We want to hear from you!
🤔If you were designing a substance (like water), that could support life on a brand new planet, what critical properties would you want that substance to have?

But when the molecules were formed in water, were they not subjected to hydrolysis right away?

This is a very strange video, but it’s just what I thought I would find. Two parts to this, just to get to waste 20 mins of my life to hear you state that that simple carbon-containing molecules were the essential building blocks that eventually arose to what we know as our “DNA, to proteins, to sugars, and also to fats? Why did you just say that at the beginning if you didn’t have anything remotely close to a theory of chemical evolution. When someone usually speaks about chemical evolution they are usually talking about how life arose from inorganic matter. All you did was basically explain that water is important for life and chemicals bond, and then said life arose from this. Huh? Water and hidrógeno is important and that how life arose, huh, WTF? You should’ve at least explained how at least one of the parts of a living cell arose, such as DNA, proteins, sugars, or fats. The funny thing is, I’ve watched all of the pros and they all say that they are clueless to how life arose, and they’ve pretty much have gave up on all the past theories apart from the panspermia hypothesis. I new not to click but I did and waisted my time anyways. 🤨
