In this video Paul Andersen describes the defining characteristics of members in the domain archaebacteria. He starts with a brief description of the phylogeny of this group. He then describes the major characteristics on an archaea, such as differences in the phospholipids. He explains how they reproduce through binary fission and finishes with a discussion of archaebacteria diversity.

Nice. I learned something from this short presentation. Microbiology has advanced greatly since the 1960's. Archaea weren't even on the 'map' back then. Thank you Dr. Anderson!
ok man
Bozeman Science with Paul Andersen are definitely my number 1 for science & biology information videos. Awesome!
Whoever you are, you may just make it so I can survive biology. Thank you. Thank you so much.
Excellent video, Paul. You make this content very "accessible" and "attainable."
si! gracias doctor anderson!
y millones de gracias al universo de las archaeas!
YOU HAVE SAVED MY LIFE SO MANY TIMES
Keep it up. Great job. Much clearer explanation.
great video, your entire series is great!!!!!
Super helpful. Nice and logical way of explaining. Thank you :)
Great educational source, thank you!!!
This video is informative and super helpful! Thank you.
Thank you very much for your explanation.
Can we switch brains for a week or two? My brain can solve Rubik's cube in under 30 seconds if that make the bribe worthwhile...
Let's do this.
Man I am late but your videos are so well made! You speak so fluently that I could watch your vid without lyrics, you speak so profesionally and rich in content that I enjoy listening to you and enjoy biology more. Thank you, from the girl from the future!
I watched this video twice or more times. I would like to press the like button one more time because deserve more than just one like
Nice and simple,keep making such videos.Much Love from Pakistan
thanks for making biology more interesting.
Very nice video and a big help for biology class. Thanks
A weapon to surpass metal gear huh.
In all seriousness awesome video. I really need to look into these guys more. Although they don’t seem too complicated. Highly specialized for specific niches.
very clear explanation THANKS!!
Great vid, thanks! A paper that was published this year (1.19.17), basically says that eukaryotes possibly branched out of archaea. Any thoughts?
This is a great video!
Wonderful. Thank you.
Thank You!!!
Mr. Anderson is someone I emulate.
Helped a lot thanks
Hi Mr Anderson, can Archaea resist any microorganisms that causes disease eg virus? Their structures are so simple and hard to think a way to protect themselves.( extreme condition is a good protection anyway but some are not in extreme)Many thanks!
Excellent video! Please, someone, know the name of the software used to make color notations in PowerPoint?
Why do branched hydrocarbons and monolayer in the membrane help them adapt better to pH fluctuations?
Great professor
i hope you're getting payed for this!
Thanks for sharing sir
Here, have my upvote. Thanks for explaining, did not understand why their membrane is so different.
+yesthisiscat_ no one can answer why their membrane is different not even they. like, i cant say why i have two eyes. but we can only say what are the benefits they are getting. first, look carefully and you will see the fatty acids are ether likage, so its more inert than a ester bond. so the change very slowly if they do. secondly, they are so long that the can cover the whole periphery so give a better uniform structure. hope that helps :)
Very helpful, just like all of your videos. :)
I'm just wondering how it came to be that bacteria and eucaryots have the same kind of phospholipids whereas archaea have different ones. Does that mean that LUCA had the bacteria/ eucaryot phospholipids and the other kind is an invention of the archaea exclusively?
When you compare proteins found in the Eukaryotic nucleus, they are more similar to proteins that perform similar functions in Archaea (not Archaebacteria). Cytosolic proteins in Eukarya, however, are most similar to bacterial proteins. It's an open question, though, whether this is evidence of endosymbiosis or the way genes assorted as the LUCA diversified into the three Domains.
thanks for make this -.-
Great description! Also, what program do you use for these Videos?
Thanks
-Andy
Screen flow for Mac I think
thank you
awesome
Nice video
Thanks alot :D
Are all archaea lithotrophs and chemotrophs? Do any of them hunt or graze on other organisms?
Sir you are best 🤗😇
What does Mr. Anderson mean when he says that the word "prokaryote" lost its meaning?
Have you made a screen cast on the process of science? Experimental design and pure vs. Applied science. Great videos.
He previously mentioned that he uses Screenflow for mac.
MUITO BOM, BEM EXPLICADO. THANKS
thnkuuuu........
Can you please tell us the difference between archae and archaebacteria .
same, archaebacteria is older name
your explanation confused me when you equalled us and bactrria versus archea... aroun 3:15-4:15
The gnome project?
Archaeal do contain cell wall. the cell wall contain pseudomurein, complex carbohydrates, or protein-glycoproteins if im correct
I love your videos, except I can never understand why you face is on the screen, taking away from the space for the information... :(
It's for the clout.
@@malachikeasler3824 facts
lol im doing this shitin class right now lmao. you are good at explaining this bro
How can I dowload your subtitle???
You can copy and paste it
Maganda pero slow down a bit kasi masyado kang mabilis.
Pero salamat sa pagpapa explain nito ng mabuti.
Pwede siya ipanood sa mga school.
the A.T.P (energy) that the archaea produces must be a very inefficient process as the cell uses it's cytoplasm (jelly) t make it due to the lack of organelle called the mitochondria which results in a slower reproduction rate meaning that they might die out
jakub rembacz you mean like every single procariot out there? Yeah sure they will die out soon
اتمنى كتابة الترجمة لو سمحت
also - only some Methanogens are lithotrophs. Many methanogens (e.g. Methanosarcina spp) use acetic acid or methanol as substrates for methanogenesis.
what is LUCA?
So how are you supposed to save the soggy jell like cute beings
Can we use electricity to kill archaeas?
The gnome project? Is this a project run by gnomes or is it a project which has gnomes as its subject? I'm hoping it's the former, I'd like to think that, by night, my little gnome goes AWOL from his pond surveillance duties and hits the hot springs to study archaea in a pair of red speedos.
'Eukaryote' or 'eukaryote'?
'Prokaryote' or 'procaryote'?
Both are correct, but they came from the Greek word "karuon", so using a k is more common.
looked over and saw a minecraft thing how is that related to this???
Some things on the side are based on recommendations, not this video.
It's funny how incredulously fascinating this is while stoned off of your ass
I am pretty sure no one says "Archaebacteria" anymore...
+Katie Beseler In my class we say it all the time lol But Im not taking AP Biology though, Im taking Organismal Bio in college with an updated textbook (:
It is outdated, yes, because now they mean the same as simply archaea.
Makes*
Exactly what I think every time =p
Matrix!
Nice attempt at describing a few characteristics of the archaea. A few corrections are in order. Archaea is a completely seperate branch from all other life forms. Archaea has no DNA. Strickly RNA. This is why they make exact copies of themselves. The term archaeobacteria was used from the 1950,s to the eary 1990,s. The gnome project confirmed the archaea have no DNA, no recognizable cell walls. Current list is 411 species. Dr Oppenheimer had discovered 24,000 species. and propagates them.
Mr Aaaanderson....
PERFECT! get a bottle of methanogens and pump in some co2 and use the methane as fuel
free fuel for marsian colonies
final fantasy 15 brought me here
liquid cyberpunk dude how 😅
Metal gear solid 5 brought me here :p
My english teacher made me Watch this
Let me teach you about Archaea Ottoia too! At 4,000 feet, the Ottoia are about as long as a pencil, with bodies about the size of a golf ball. But those at 20,000 feet have been found to eat full-grown sharks! At 30 or 40,000 feet... Well, you do the math.
"Ottoia is a stem-group archaeopriapulid worm "
Different thing entirely.
archea is a microbe and so the bacteria is
but archea isn't a bacteria right ?!
+Yosra Shedid Right xD
Yosra Shedid Yes they are. They're prokaryotic bacteria that are closely related to us.
Bacteria are a type of microbe. Archeaa are a type of microbe. That doesn't mean that bacteria are archeaa, or archeaa are bacteria.
god I'm so confused
Archaea can still have peptidoglycan
+nicofire0987 I've never heard this before, what is your source of information?
+nicofire0987 how?
They can have a peptidoglycan-like substance, cant think of the specifics right now though. Source 3rd year biochem major (lehinger textbook)
+nicofire0987 I thought the whole reason for the classification of archaea, is that they're prokaryotes that do not have peptidoglycan cells, any other bacteria that does would be in the domain eubacteria
Blessing youre correct
There is no common ancestor
An archaea is not a bacteria!!!
+Adriel Castillo
He didn't say they were bacteria. He said "archaebacteria"...
Archaebacteria is what they used to be called.
From these video am not going to these white teacher
Who cares about being condscending. He's just fucking wrong. It's sad when commenters try to confuse students on learning videos.
Archaebacteria is an outdated term. I am infuriated and disgusted! I am received at this outrage. I'm gonna have a BF and write a letter!
Complete bullshit he's maked all things fully confused
thank you
