If you’re struggling, consider therapy with BetterHelp

@SoraHjort

Gez, betterhelp is really trying to do a redemption tour/history sweeping with all these sponsorships on various channels after the stuff that went down a couple years back when they got caught mishandling patient info and unqualified professionals they hired. Selling patient info to various people should have destroyed the company... I mean when you get the FTC going after over it, you know you've screwed up.

@jasperdragon00

glad your channel is getting sponsored, but i must remind people that betterhelp does not have the best practices and they have mishandled medical data as well as hired therapists without qualifications that have severely mistreated patients. just want people to stay safe </3

@kylezo

This is sooooo weird if you actually pay attention to it. the sudden music shifts, unrelated footage, the way he repeats himself and continually changes the way he pronounces things, lol. it's really actually even more hypnotic in that way. it keeps you kinda dizzy lol

@Oberon4278

My favorite part of KZbin is how they time ads perfectly for when I'm almost but not quite asleep.

@SenorTucano

A change in ocean chemistry may have played a significant role in the Cambrian explosion. A gradual change from acid to alkaline would have permitted calcareous exoskeletons to evolve.

@gabbyn978

I once read a biography about Wallace. In that book, it was said that Wallace (who gave the Wallace Line its name) contacted Charles Darwin, in order to discuss his own findings. Whithin the correspondence, he asked Darwin to publish their common idea in his book, as Wallace had the feeling he was not confident enough and would not be able to deal with the backlash that such a thesis would cause. So there was no competition at all, Wallace simply left this task to Darwin.

@PaleoEdits

Finally! My favourite earth-history channel returns!

@HGGundamPlays

One of the theories I've heard that I like to explain the Cambrian Explosion is the ending of one of the many Snowball Earth era's, all the extra mineral material being washed into the oceans gave life a much more diverse chemical and mineral soup to evolve from.

@AldrinAlbano

This episode was a 'Tour de Force" to explain our current understanding of the Cambrian Explosion [of life] on Earth. Worth every minute of my Christmas Holiday vacation. Thank you so much!!

One thing to keep in mind, a "moment" in the geologic timescale could be 10's of millions of years.

@Wandering_Chemist

I was the one who kept bothering yall for a new episode of History of the Earth for what 6 months now? And gentlemen, you made the wait worth it more than you could ever know! I fucking love this series. Thank you 🙏 and hope you enjoy your holidays cheers 🍻

@j.campbell4497

Just amazing how you consistently turn out the highest quality content on KZbin. Thank You!

@eokic

I love these videos but can you please reduce the music volume throughout? And the jumps in volume when the narration stops are quite annoying

@oobrocks

Incredible doc, including “we don’t know and maybe we never will “.

@neongreenon

I love your channel, but I wish the sound was more smooth~ like the music in between thoughts/sentences is always so much louder than the narration.

@solitudessilentgroove

Constructive criticism on audio edits - I often fall asleep listening to KZbin. When the narrator has a nice voice it helps me sleep. This narrator is perfect, but the music edits that go up in volume in-between his words is very distracting and even wakes me from sleep. I suggest just leaving the music volume steady and not making it go up and down with the talking. Thanks for awesome content.

@popman48

Leila, Pete, and David, this series is, in my opinion, the best series on KZbin. From research/writing, to editing, to presentation, it is absolutely top notch. I watch a lot of content on KZbin and some of it is well done, but none as good, in total, as what you do. Just Wow! Thank you for the hours and hours of work that go into each episode. I learn so much from each one. I wish everyone had the luxury of time to experience these gems.
