    And although horseshoe crabs made it to modern times and trilobites didn’t, they both have ancient beginnings. The oldest known trilobite is ~540 million years old, but the horseshoe crabs weren’t far behind with the earliest example showing up ~445 million years ago. So technically just looking at a horseshoe crab you’re looking back millions of years into the past.

    I love the blatent respect these three have for each other. These kinds of channels can sometimes devolve into a set of people that have no interest in each other outside of work, but these three are clearly intelligent in different subjects and totally respectful of each other's strong and weak points. It's a brilliant thing to see and gives me yet another reason to love this channel

    Hank is amazing, a great communicator. Thanks for this live stream, it made me realise how amazing the whole team is, keep it up.
    I’m working through the playlist, so I’m a lucky person who has some more joy to come.
    Thanks guys.

    Horseshoe crabs do their thing in Southern New Jersey as well. I lived in Cape May and I used to hate the early summer because they would die by the hundreds right across the street from my home in a bay no less. The birds certainly eat the remains and a loss of that food source would be dramatic. Also the smell of rotting crabs was one the reasons I can't eat sea food.

    First Thing. PBS Eons is my new favourite youtube show. It majorly presses all my buttons.
    I love the content (focus & timescales) and format (under 10min, simple studio based, clearly illustrated) and the presenters are perfect for it. Neither over-boffiny or cheesy-cheesy, just perfect.
    So thank you presenters and Eons for everything. I actually look forward to your new videos a lot. Eagerly and in rapt anticipation!

    Second Thing. re suggested topics for future issues, can I propose ‘Gender’. It sort of naturally follows on from your ‘How Sex Became A Thing’, but that was more focused at a cellular level.
    I am not sure how best that 'Sex' starting point might be expanded upon as a concept using ‘Gender’ as a catalyst or key, but I feel there is a bit more to it worth exploring with regard to the development of life on earth.
    For example how reptile eggs (reptiles are dinosaur-y) can develop as male or female depending on the temperature they are incubated at.
    And recently there has been the story of the Crayfish that has mutated to be able to self-replicate (step-back or forward re evolution of 'Sex' as a thing?).
    Anyway Gender seems far less clear cut and far more contingent on external conditions than we may initially think. And that cross-crossing between geology, biology, climate, to give an interconnected overview of development of life (rather a view polarised perspective according to specialist lens; biology, chemistry, physics, etc) feels to me to be at the core of the Eons mission.

    Resources. Kallie suggested ‘The Story of Earth’ (Hazen) in this livestream as recommended reading. I will definitely get that. In a future livestream could ‘recommendations and further reading/viewing’ be extended upon? Maybe each team member suggesting a favourite book, documentary, resource etc, that they think would advance & enrich Eons fans ‘home study’.

    Last thing. After all my positive feedback I thought I would mention the only thing I have found a negative during my viewing (I have watched all the Eons episodes and will continue to do so). And it was the loud & intrusive ‘background music’ in the ‘How Sex Became A Thing’ episode. This may be an autistic thing (I’m autistic) but it’s hard for me to tune out 'not important noise' (muzak) from 'important noise' (presenter), so I struggled a bit with that episode.
    One big thing I love about Eons format is that you keep it simple but not boring; no loud background music, chaotic OTT graphics, or ‘wacky’ (aka annoying) humour that gets in the way of you communicating your wisdom. I know the pressure to go the populist ‘infotainment’ route might be huge, but I think there is too much of that and not enough of what you do, which is clear, sincere, direct… perfect.

    Anyway, that’s my essay. I’ve meant to comment lots of times as I watched the series but didn’t, so have got it all into this mega comment.

    Keep up the stupendous work. It’s already ‘must see’ essential viewing for anyone into this scene, and can’t help feeling there is still greater to come. It’s pretty damn exciting.

    i've long wondered what to donate my body to (including that museum in Denver), but i would totally go for your fossilization idea. i have a spinal cord injury and several metal parts, might be interesting.. is there a way to find out where dead me would be most useful?

    25:00 Ampoules like that are pretty common in chemistry, when you have chemicals that are extremely air sensitive. Once they're broken open the shelf life can be minutes or less, and of course some things have to be handled under inert atmospheres.

    As far as body preservation, wouldn't the best be an artificial amber? Suspend in resin, then bury that in the most stable formation you can find or make?
