The History of Red Algae

Imagine that you aren’t watching the microcosmos right now. Instead you’re living in the world as it existed around one billion years ago, and you are the ancestor of this red algae.

It absolutely destroyed my brain when I learned that Kelps are not plants, animals, or fungi, but have convergent-ly evolved photosynthesis with plants and mostly just share an appearance. wtf

Yay Archaeplastida ('ancient' 'plastids') !!!
I actually helped to come up with that name. Nice to see it adopted in textbooks and by you.

One small comment, I now exclusively use the term cilium (pl. cilia) to refer to the eukarytotic organelle so that folks do not confuse this organelle with the 'flagella' of bacteria which are completely different.

Man, journey to the microcosmos is like one of the best things. Of all the things.

[Linus]

These are so soothing, i love these videos

[Autrone]

Please do more videos on protists! I love them! Maybe a specific video on dinoflagellates? The way they light up the seas is fascinating in its own right!

[udoberend]

What a quality video again! One of the best voices on the web today, keep creating Hank! ;-))

[Ahamkeira]

You're about to lose a quarter of your genes" *hard go to still image of red algae and logo* lmao why was that so funny

[asinglebraincell]

Red algae is so cool and fascinating. there are so many interesting types of life on this planet 😮

"Nature's boundaries are porous and, and its identities are multi-faceted."
The instant I get an opportunity to say this in a conversation I'm gonna say it.

Great video! I love how it presents in simple words some of the most amazing features of microcosmic life (horizontal gene transfer, endosymbiosis)!! Keep up the perfect work!!

[MicroSaner]

Great video as always! You inspired me to start on youtube! :D

[madamsloth]

Great video. I am surprised by how much we know and yet there is still more that is not understood. Wish i had paid more attention to how to become a scientist when i was younger, i want to be paid to learn new stuff 😅😂

Every time I've watched this channel, I've always told myself, "The narrator sounds EXACTLY like one of the Green Brothers' " --- and I've been watching this channel for a good while now, yet today -- just now -- was the first time I actually took the time to look (it's right in the description, DUH!"...! Yup... It's Hank Green... No idea why I never checked before -- guess it wasn't really that important to me (or perhaps I didn't want to ruin the mystery if it was NOT him), but I just enjoyed the videos, so that is what was really the important thing... 😁

i can't wait until horizontal gene sharing is used to explain a chimerical shapeshifting monster like John Carpenter's The Thing.

[Hydrosized]

I can’t imagine when you are talking Hank!

[ajchapeliere]

It's wild that complex life basically arose from the cellular "get in, loser. We're going on a trip through deep time"
The world is friggin amazing

[MsAwesomeify]

it's crazy how good these videos are to sleep to

[tiffanymarie]

If there's a niche that can be filled, life will eventually uh find a way.

[GeoffryGifari]

Hmmm... do we know the mechanism by which organisms can lose genes over time?
Is there something like a metabolic cost of maintaining a long genome?

I miss your guys' original intro beat. I think it would have been perfect with the intro on this video where you cut straight to the music after your climactic and intrigue inciting whip-snap of an end note to your intro. That's probably a weird description but I haven't figured out what writers and speakers call that type of speech structure.
