I don't understand why this series has less views than your "regular" work, but please don't give up. It's quality is phenomenal.

[marinaaaa]

You have no idea how much ive been looking forward to this. This series will truly show how versatile this channel's concept is

[Mersault]

Years ago, back in 2021/2022, I worked for Matt and did the research for the update of this chart. I am very happy to finally get to see the end result. He even added a picture of my pet rabbit for the rabbit on the chart. I t was a great job working for Matt, and I absolutely love getting to see this chart finally.

How do people NOT love learning about this??? It's our history from the beginning. Gives us an idea of how life/the earth was millions of years ago. AMAZING!

[WolfhoundK]

Honestly if you just used this video to replace the second half of the first lecture in 95 percent of level 1 undergraduate biology classes in the English speaking world it would be a net positive. Thanks for everything you do with this channel.

17:21 That's not why starfish (and all other echinoderms) are bilaterally symmetrical. They're bilateral in the larval stage of their life cycle, but when they settle down on the seafloor, they develop their adult bodies; the larval left side becomes the adult underside, where the mouth is (except in crinoids) and the larval right side becomes the adult overside, where the anus is (except in brittle stars). Adult echinoderms usually have 5-segmented radial symmetry, where their body parts repeat every 72 degrees you travel around the centre of the organism.

Your ability to arrange so much complex information is a beautiful thing, plus walking us through the chart is so engaging, I'm very excited for the rest of this series!

[GiatrasKon]

A small correction/clarification about starfish: they are considered members of Bilateria because of their evolutionary ancestry, not because of their adult body symmetry.

Starfish belong to the phylum Echinodermata (also includes sea urchins and sea cucumbers), and during their larval stage, they exhibit this bilateral symmetry. Later in development, they undergo metamorphosis into their adult form, which is radially symmetrical.

Despite this change, their classification in Bilateria reflects their evolutionary history and developmental patterns, rather than their adult morphology.

I'm so excited about this video series! Your original evolution chart video is why I started watching this channel in the first place, years ago~

This is the most thorough discussion of the Tree of Life I have ever stumbled upon outside the Biologi classroom. Amazing job making this available for free on youtube, I will be buying some of each chart to hang in the classrooms at my college :) Minor nidpick: Adult starfish does not have bilatteral symmetry, but radial symmetry. They have the mouth on the bottom and the pooper on top, and for the starfish in the picture is therefore pentaradial. They are clearly bilatterally symmetrical in the larval stages and their close Echinodermata relatives Sea Urchins and Sea Cucumbers are also closer to bilateral symmetri so they clearly belong in this group but is a good example of how we humans want nature to fit in nice little boxes and nature just shitting on our need for order :D

[EricMagazu]

Professor Baker, you are obviously the preeminent polymath of our age. Thank you for your wisdom and systemization!

Just as the video was saying, "the tree that connects every loving thing, " I turned to my dog and said, "it's your family tree, too. And mine." He looked at me like, "weirdo." Too bad for him, I get to pick what YouTube plays.

[GoNoctis]

I love all your hard work. You help lift me out of my chronic pain.

[WaluigiPlushBros]

Let’s GOOO, been looking forward to this chart. This took a lot of hard work, Great Job!

[MB]

Babe, wake up, a new Usefulcharts into just dropped

[cpegalaxy]

Love how simply you explain vital concepts in evolutionary history!

[ssteeeeeve]

The evolutionary life tree itself evolves

I keep clicking the like button because I keep hearing major agreeing moments. What a well-researched, well-translated science. Thank you!!!

[Logan_Bishop_YT]

I want to tell you all something. One year ago, if you asked me if I would ever accept evolution as a coherent scientific theory, I'd call you insane. But back in November 2023, something happened that made me want to debunk evolution once and for all. And since I thought I had a pretty good grip on science at the time, I thought I could do it. But I failed in about a month. But I learned to reconcile my faith with evolution, and I am still very much a Christian. If you are a creationist and watching this video, just know that you can be a Christian and accept basic scientific principles like evolution, since Evolution does not contradict the Gospel.

I had a sibling growing up that had a lot of aquariums with different types of fishes or reptiles. Two aquariums had lungfish in them. It was pretty cool.
