How Evolution works

Kurzgesagt – In a Nutshell | December 14, 2025



The mechanisms of evolution explained in one video.

The theory of evolution explains how the enormous variety of life could come into existence. How it is possible for primitive life forms to spawn the millions of different creatures, that exist today. Unfortunately, evolution is often misunderstood, because it’s mechanisms seem counter intuitive. By using visualizations, infographics and appealing characters, the viewer is more likely to understand it the complex information. More than that, by presenting the information in an entertaining way, the information is more likely to sink in.

Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking. Because we love science.

We would love to interact more with you, our viewers to figure out what topics you want to see. If you have a suggestion for future videos or feedback, drop us a line! 🙂

    I just got your art book and 12026 calendar.
    But really I just need a digital bookmark
    Bracause I don't use twitter anymore.
    So my tweet would be
    "I'm calling it now, the "Sean Payton sandbag theory". Sean Payton is callin bad plays to underrate the broncos. We're gonna destroy playoff competition. Bo nix is locked in. We're going to the Super Bowl. He knows what it takes. We're going all the way"

    7:50 Oh really? I don't see humans making any effort in this regard. Trust me… animals don't give a rats butt about this. They see a female and think "I'm horny, I need to have sex… NOW!"

    9D 2025: “The video was a whole vibe—some students thought it was lowkey beautiful and had that rizz, while others felt major skibbidi brain rot and got uncomfortable. It definitely cooked up big thoughts, had people questioning stuff, and even left a few saying they need therapy to process. Overall, it was wild, thought-provoking, and not mid at all.” – AI Helped them to write this comment.

    24th of November 1859

    The 166th anniversary of that great day is fast approaching.

    On that day, the entire edifice of organised religion, and every creation MYTH, collapsed like a house of cards. 🥳

    Make a note in your diary. 😉👍

    Most mammals do not see in 3 colors. The gene that allows humans to see yellows, blues and reds is only found in one group of animals, primates of which we are a member species. Some 40 million years ago a gene duplication mutation occurred doubling the OPN1MW gene sensitive to the yellow/green section of the light spectrum and a later mutation of this resulted in the OPN1LW gene that enables primates having this to see the color red. This mutation is unique to primates and as a primate, we too have this form of color vision.

    All things bright and beautiful, all creatures great and small – All things bright and beautiful were made by super-fecund imperfect replicators under selective pressure.

    So… In order for a data to be exist there must be an intelligence!

    And intelligence without power cannot create!

    So…. There should be Power too!

    Power and Intelligence worth less without Will!

    So…..at the end, there must be a an Powerful intelligence that have will.
