About 1.8â0.8 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 âthe dullest period in Earthâs historyâ; but if you look a little closer, thereâs a pretty interesting story to tell.

I miss the Dalek
đ Bravo on a perfectly written video, Lucas Kavanagh. 90% of what Hank said was understood by my terrifically tired brain. đ§
Sex was invented during "The Boring Billion". Video title checks out.
I feel like this is a good example of talking about non-change. Like we always want an explanation for change, but asking why something didn't change is also useful and insightful
PBS Eons watches with stolen thunder in the corner.
at what point in earths future will the sun win over the moon
Hank and the Sci Show gang, you are all heroes. In today's world ignorance is a choice. And, you guys are fighting ignorance on a global scale. Brilliant.
09:49 Some serious problems with the analysis here, at least how Hank is explaining it. The Earth slowing or speeding up its rotation doesn't effect the total energy the Earth is receiving, so the lengthening of the Earth's day doesn't increase the amount of energy any photosynthetic life receives over time.
The somewhat less complicated billion?
S c I e n c e đ€
Also, carbon taxes will fix all of this.
HANK HANK HANK
Let the Sunshine In…
My immature butt kept wanting to hear torque as twerk
The Billion Years Buffering
The moon keeps looking more and more important for life … can we give Mars a decent moon? Is Mercury doing anything really important?
A lot of the evoutionary changes that occurred over the "Boring Billion", did so at the scale of cellular chemistry, giving rise to much of the complex molecular "machinery" which allows modern eukaryotic cells to do much of the amazing stuff that they can today. Unfortunately, these microscopic structures aren't capable of fossilizing, tending to break down into their composite chemistry because of the heat due to the mineralization of the surrounding sediments. This means that the only way we could know anything is happening at all is by analysing the chemical changes in the layers of rocks over millennia – something virtually impossible to do given the lack of surviving sedimentary rock from this time (most of it having been subducted & converted into metamorphic minerals).
I love the graph at 8:54 , I was thinking that global ice sheets would reduce the moon's torque. That graph does show a large dip in the region labeled "Snowball Earths".
We need more co2 not less.
The Brewing Billion, or Brooding Billion.
Love this hypothesis, lovethis video
Really well done
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.

âIt is also when sexual reproduction startedâŠâ Hey! My favorite past time, so thank you Boring Billion!
Please explain something to me, if the length of the day is longer, how does that allow more photosynthesis? Isn't the amount of daylight and the amount of darkness still just 50% of the time averaged out over the course of a year whether the days are 19 hours or 24?
Maybe I'm not asking this correctly. But let's say we took a sample of 100 hours right? About half of that is going to be daylight and half of it is going to be night time, it doesn't matter if you break the chunks up in to 19 hour chunks or 24-hour chunks does it?
I teach life science to 6th grade, earth and space science to 7th, and physics to 8th. This video has everything! Thanks you guys. Please keep doing what you're doing.
multicellular organisms AND sex were just popping up and we call it the boring billion??? damn
Challenges promote cooperation, make sense.
so you're saying we survive by breathing bacterial farts?
Poor guy, doing mental gymnastics lol to explain the complexity of life. That's a lot of coincidences lol đ
Hell we shouldâve just called the void billion
This one really blew my mind
You are a incredible human being, thanks for the content <3 <3 <3
Hank has changed.
Episode idea , when you back is ichy and you get some one to scratch. It why does the itch travel to different spots
Completely fascinating.
'Billion years of childhood development for the plant' seems a little too long đ
I love these mind-bending, over-arching dives into meta-science! (I tried to come up with some more hyphenated words but decided this says enough; I wouldn't want to over-think it.)
2:48 Based on personal experience with driving, I have to point out that maybe…just MAYBE…the Indian plate had the right of way, and the Himalayas are the result of the Asian plate refusing to yield…
đ
What it we called it the Rotational Equilibrium Period?
Its either that, or aliens
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?
0:17: đ The 'boring billion' refers to a period in Earth's history where not much changed, but it still holds interesting stories.
2:32: đ 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: đ 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: đ 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: đ 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.
