This time (2.1-2.2 billion years ago) was when the first traces of oxygen appeared in the atmosphere (and probably more of that in the shallow seas where cyanobacteria produced it). So it was the earliest time when multicellular life could appear (oxygen respiration provides more energy than other forms of metabolism). The only surprise here is how quickly evolution used this opportunity.

I love getting home from work every night and watching the new anton video with my dinner

[scottgardener]

Unless it did succeed, and lasted for several hundred million years during the “boring billion, ” but didn’t evolve hard shells or other fossil-forming remnants, before finally freezing to death or getting killed off by either too much or too little oxygen? I know, no evidence of it, but hypothetically possible?

This channel is so important to those wanting to stay informed about cutting edge science and discoveries. Thank you Anton xx

Anton - I Love your videos. And your dedication. And I love the fact that SOMETIMES, you sheepishly ask people to subscribe, because you intend to cover a topic when more info is available. But you attack the "SUBSCRIBE" topic so, so sheepishly. You're so, so humble. YOU'RE A WONDERFUL PERSON. And we, your subscribers and folk who watch your videos.... we appreciate you. And your dedication to bringing us science in "layman's" terms. Sent you a tip, in thanks from us all. Keep up the good work. You're appreciated!

Anton, I love your videos. I’m a geologist and an earth science teacher at a state university in California, and I still learn so many new things from you.

[TheDillyum]

I love you Anton you make each day a little bit easier and more fascinating! Thanks for all your hard work!!! <3

"to see how this comes out in the end" Glad to know you're planning to keep putting out videos right up to the heat death of the Universe. I'm all in for that!

This happens H. G. Wells' "The Time Machine" when he travels far into the future -- he witnesses humanity die, and then new signs of complex life appear but then die off before they gain momentum. I always thought that was such a nice touch.

[SiqueScarface]

I was at Vienna Museum of Natural History 10 years ago and saw the exhibition. And indeed, the presented pieces were looking surprisingly lifelike. And the museum was quite sheepishly admitting that they invented the word Gaboniota (Gabon-animals) to create debate.

I appreciate the implication this has for the "great barrier" solution to the fermi paradox. If true it could be strong evidence that the "great barrier" is the formation of multicellular eukaryotes.

When you consider the universe is around 14 billion years old its pretty amazing how "young" the universe is considering how long we know it'll persist. Further it's incredible how early in the universe's life Earth first developed (4.5 billion years ago) and if this is confirmed then it gives us new numbers to run and see a rough estimate of how many planets in our galaxy alone could harbour multicelled life

always around 15 mins of good info to know, thanks Anton. 👍

[ijarbis]

I can’t believe this content is free. I’ve been watching you everyday for over a year now and I hope you never stop making videos. Thank you Anton!

[willhandy]

Again, important stuff, really well presented. You make it clear how wildly exciting this would be if the discovery turns out to be complex life. (Those possible burrows are SO suggestive!) And you make it equally clear that it may have nothing to do with life. For me, this left a sense of excited anticipation with little commitment to one interpretation or the other. This is up to your usual high level.

[jimcurtis]

Wonderful as always Anton. Thank you. ✌️😉

[GeorgeNoX]

Considering how many cataclysmic events Earth has experienced in the past it is certainly possible that there was advanced life before but got wiped out. It probably happened multiple times in fact. Earth is 4.5 billion years old, there is no way there was no complex life before the oldest one recorded so far. We just can't find anything that far in the past, doesn't mean it wasn't there at some point

[tuffymartinez]

Thank You Anton...VERY, VERY, COOL nice to hear the latest. Much appreciated....TM

[nameless]

love the "subscribe and stuff" with the lil pointy fingers

[George-rkts]

Wonderful way to end the workweek.

Thank you, Anton
