    About 1.8-0.8 billion ago, the Earth went through a period known as the Boring Billion, where not a lot changed in terms of geology, evolution, or even the number of hours in a day. Some scientists call it “the dullest period in Earth’s history”; but if you look a little closer, there's a pretty interesting story to tell.

    Some really impressive stuff had to have been happening in the Boring Billion. After all, before it, all we had was Archea, and after, we had Ediacaran life. It's really the fuzziest part of evolution to me- animal evolution makes sense, and abiogenesis makes sense. Even the evolution from archea to basic eukaryotes makes sense. But what about the part between basic eukaryotes and the very first animals? I feel like nobody talks about that

      Oh, they are. The first animals and fungi probably date to the end of the biting billion, a billion years ago. They also turn out to be each others closest relative, and share more characteristics they one would think (external digestion, for example, and having a single posterior flagellum). The fungi, along with green algae, may have colonized land that early as well. (Land plants and animals would take another 500 million years).

    0:17: 🌍 The 'boring billion' refers to a period in Earth's history where not much changed, but it still holds interesting stories.
    2:32: 🌍 The Earth's continents merged into a supercontinent called Nuna, which later broke up and reformed into a new supercontinent called Rodinia, with implications for the development of complex life.
    4:45: 🌍 The Earth's rotation and the moon's orbit affect each other, causing changes in tides and lengthening of days and lunar months.
    7:10: 🌊 The study uses cyclostratigraphy to determine the number of daily tides in each lunar month and the length of each day in the past.
    9:33: 🌍 The video discusses the theory that a steady spin rate of the Earth during the 'boring billion' period may have affected the evolution of life and the increase in oxygen levels.

    Huh. I've always thought of the Proterozoic as the "Age of Basins" rather than the "Boring Billion", despite it not being an era of deep interest to me (I was fascinated by Archean geology). A lot of important basins formed at craton/continent margins during that time, which have stuck around to this day. It may have been a fairly stable time in geological terms (though events such as the Keweenaw rift/Grenville Orogenic event would show that geological activity was certainly not absent), which was likely important for life to stabilize and develop; too much excitement (geologically speaking) tends not to be very good for living things.

    The Boring Billion wasn't completely boring with regards to geology - there were some orogenies (mountain building events) during the Boring Billion - the Penokean, and Grenville Orogenies for example. Also, don't forget that the Mid-Continent Rift that almost split North America in half, occurred 1.1 billion years ago, which was during the Boring Billion.

    always amazes me how life survived while it accomplished first essentially bleaching itself, then freezing itself, and then being suffocated over and over again. It makes one wonder if life isn't way more common in our galactic neighborhood than you might suppose.

    I thought I had already heard a lot about the boring billion, but a lot of this was new! Also, I grew up in Sudbury, site of a gigantic asteroid strike 1.8 billion years ago - always wondered if this was also figured into the equation?

    * Photosynthesis had been going on for much longer, but it didn't produce oxygen.
    * Longer days don't make for more daylight in the course of a year or longer, but it would make for more daylight at a time, and that might make photosynthesis more efficient.

    I think they are underestimating the effect of the distribution of continental land masses. This can drastically change the resistance to the tidal flow.

    I think the UV shield animation at 2:13 is of something else, maybe IR. Most of the sun's UV is _absorbed_ by the Ozone layer (which is concentrated in the stratosphere), and turned into heat.

    How is it that the suns affect on the atmosphere to make torque would equal that from the moon since the water would have so much more mass?

  • @rayneweber5904

    @Scishow 9:23 you say the "sun's torque" when I'm pretty sure you mean "Earth's torque".

  • @Dogtroll
    @Dogtroll 9 місяців тому

    The problem with the hypothesis that life caused an increase in the torque of the sun versus the moons torque causing a pause in the increase in the length of days on earth is that life still exists on earth, so why hasn't the earth's days continued to decrease once that process crossed over a threshold?
