Endosymbiosis, Choanoflagellates, and the Origin of Animal Life

When we discuss zoology, we are always also talking about evolutionary biology. And with evolution, we are sometimes concerned with origins. What is the origin of animals? What is the origin of eukaryotes? What is the origin of life on earth in general? Let’s try our best to briefly answer these questions now!

  1. Hey Dave, I try not to bring the whole debunking part of your channel over to your informative videos, but I feel like this is the best way I can reach you. Do you plan on talking about the trend in conspiracies and vaccine misinformation in which people say that graphene is in the Covid-19 vaccine? I've seen a lot of people on bitchute and whatnot peddling that recently. Although I imagine there isn't much to disprove, it's just factually incorrect.

  2. Professor Dave , Could you please explain why, when I was a teen, I would cut the grass and it would lay on top of the lawn for several days even decomposing and becoming fowl smelling. But now PD I'm 60 and when I cut the grass, it becomes completely DRY within 3 HOURS! And turns completely BROWN by the next day! Thank You in advance.

  3. I had just finished watching your videos on James Tour Origins of Life (OoL) and thought, "I wonder if Prof. Dave has done videos on endosymbiosis. That would super cool", as it's one of my favourite aspects of OoL.

    Lo and behold, you had just uploaded this video! Thanks for the great work as always.

    If I wanted to learn further about this subject, or any subject you've presented, what would you say is a good approach?

    I find I often got sucked into particular part as there's so much to learn. While I do enjoy that, it feels it's an ever growing mountain of knowledge I need to learn – as one I'd like to eventually be able to contribute and do my own research.

    I've completed my undergrad, however I'm not in the position to be able to go complete a masters. Would it be better to pick a single subject, become well-versed in it and then start expanding; or to learn a bit of everything and build everything up slowly?

    There's so many directions to go, that it's difficult to know which way to go. I suppose an answer would be to just pick and direction and just go.

    Thanks for video, and for the read. Stay hydrated

  4. If a horizontal tube contains a flowing superfluid, and a small strip of free floating paper oriented perpendicular to the longitudinal axis of the tube, is exposed to a instantaneous change in direction of the fluid, does the paper strip change position?

  5. It is better to remain silent & thought a fool than to speak & prove it…Very interesting how all your videos contain cartoons & CGI…No real images Science indeed

  6. I just find it hilarious when people are like “the math makes evolution impossible” when, in reality, math is one of the best pieces of supporting evidence for evolution

  7. Super into everything you have ever said until I heard " spontaneously forming lipid membranes". Huge fan of your channel and your debunking mission. Can you please explain spontaneous forming lipid membranes? I am with you on the results, but spontaneous is not a science word. I would even say it's a word used by con men to try and pass thier hokem. Please elucidate my misunderstanding of this word and or hypothesis. That word so ugly. It's a human word… "spontaneous" not a science word. It describes human interactions not falsifiable empirical evidence. Much love to you prof Dave🤙
