I had a friend in elementary school whose dad used to say "Your mother wasn't a glassmaker" when somebody stood between him and the television. In the case of diatoms, their mothers quite literally are glassmakers.

Rest in peace, Klaus Kemp. He made BEAUTIFUL artistic arrangements using diatoms and a photographic microscope.

The culture of pressuring ourselves into pretending we know everything about everything has to come to an end and I feel like your video does an amazing job at providing a platform for this. Being an educator never had to mean that you know everything about everything and can pronounce every word. We're all on a learning journey and that's just how it is. I appreciate your humor and your willingness to just be yourself.
@EchoByrnes
12:40 Thank you. You're legitimately the first actual real scientific educator thats told me this. I have awful generalized anxiety disorder, and all I ever hear talked about is how the planet is almost dead. It makes me really depressed and hopeless. I'd already sworn off having children because I didn't wanna bring them into a doomed world. Thank you for giving me hope

Okay I did a quick comment skim and now several months after the video was published I’ll try to explain a molecular clock. Basically some parts of an organism’s genome are going to be extremely important for the continued function of said organism - stuff that codes for functions relating to basic metabolism, for instance. Because these parts are so important, mutations that occur which change the output are unlikely to be passed on (because the organism won’t survive). Therefor all the changes that accumulate in these regions of the genome are going to be neutral mutations - mutations that don’t actually change the output of that region. Since those mutations are neutral, any one mutation is just as likely as any other to be passed down and become “fixed” in a population (as more individuals in a population branch off of that original mutant parent, and you have mixing with other parents, etc). This process of neutral mutations accumulates at a pretty constant rate which is calibrated against fossil and historical records. So you can compare, say, genes for hemoglobin between horses and humans and see the difference between the two of them and get an idea of how long ago the two species diverged just based on how different these regions of the DNA are.

As someone with thalassophobia, your videos content is terrifying, but your presentation is so fun I can't stop watching them. Thank you for making facing my fears more fun!
@AlexIsOffline
I'm so in love with your content. And while that's partly attributed to my complete love of the ocean, your way of delivery, editing, and tremendous care and effort really makes your videos resonate with me. Since I have ADHD, I so easily zone out even when watching things I'm interested in, but you always have my unyielding attention! Side note, I'm so happy to see the how much the channel has grown in the past month!! You deserve it so much :D
@kylesty6728
I feel like the bizarre nature of diatom reproduction is very little known. The progressively smaller shells until they “reboot” and all that. Might be worth a part 2 sometime.
@lughd5578
I think I'd want to have a frustle made of really soft fabric...No more dealing with sensory problems if I have a layer to protect me!!!

0:32 not the guilt tripping that is trademark of Cows :O your really cool!!!
@mistformsquirrel
Thank you so much for that little rant about how there is no singular "point of no return" - we can beat this. And that's true for literally every other problem on this planet too. Never give up. So long as people are alive and care, problems are solvable.
@perhapsitsfunpop1071
I think if I had to be encased in a frustule, I’d probably want it to be bouncy so i could just fall and bounce everywhere I wanted.
@jackdog06
As a computer science teacher, this was a bold choice for YouTube recommendations to throw at me, but I’ll be damned if this isn’t top tier marine microbiology content and I am HERE for it.
@vurtua7
Molecular clock is a figurative concept used to date things based on the rate at which they mutate, so basically checking their sequence to other lineages to find difference, then doing some math to figure out when those differences occurred to get an approximation of how old that particular mutation is, and therefore how old that lineage is.
@matthewpitre8159
I learned about diatoms from true crime of all things apparently they can figure out what body of water or even dirt you've been in by what diet tones are found on the body or around the crime scene kind of like using leaves to determine if you were in someone's backyard that has a certain type of tree. Because there are so many different diatoms and they live everywhere but there is usually specific ones found more often in certain places than others
@zehkiel8018
Gotta say, I respect the hell out of you admitting you didn't understand some of the papers.
@86davy
What video did I accidentally click on and how did I go from confused to absolutely captivated without noticing? I’m subbing
@sarahthesarah2850
As a moderately expressed introvert , I am already in a social frustule. Great episode. I am now an instant subscriber.
