- Life on Earth 005 - Archaea
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!
Excellent video, Paul. You make this content very "accessible" and "attainable."
si! gracias doctor anderson!
y millones de gracias al universo de las archaeas!
Whoever you are, you may just make it so I can survive biology. Thank you. Thank you so much.
YOU HAVE SAVED MY LIFE SO MANY TIMES
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!
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.
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
i hope you're getting payed for this!
Great vid, thanks! A paper that was published this year (1.19.17), basically says that eukaryotes possibly branched out of archaea. Any thoughts?
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.
Mr. Anderson is someone I emulate.
Great educational source, thank you!!!
Keep it up. Great job. Much clearer explanation.
Nice and simple,keep making such videos.Much Love from Pakistan
This video is informative and super helpful! Thank you.
Super helpful. Nice and logical way of explaining. Thank you :)
thanks for making biology more interesting.
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?
Why do branched hydrocarbons and monolayer in the membrane help them adapt better to pH fluctuations?
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 :)
Great description! Also, what program do you use for these Videos?
Thanks
-Andy
Screen flow for Mac I think
Excellent video! Please, someone, know the name of the software used to make color notations in PowerPoint?
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!
Thank you very much for your explanation.
What does Mr. Anderson mean when he says that the word "prokaryote" lost its meaning?
great video, your entire series is great!!!!!
Are all archaea lithotrophs and chemotrophs? Do any of them hunt or graze on other organisms?
Very nice video and a big help for biology class. Thanks
Thank You!!!
Archaeal do contain cell wall. the cell wall contain pseudomurein, complex carbohydrates, or protein-glycoproteins if im correct
Have you made a screen cast on the process of science? Experimental design and pure vs. Applied science. Great videos.
Can you please tell us the difference between archae and archaebacteria .
same, archaebacteria is older name
This is a great video!
He previously mentioned that he uses Screenflow for mac.
very clear explanation THANKS!!
Great professor
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
Wonderful. Thank you.
your explanation confused me when you equalled us and bactrria versus archea... aroun 3:15-4:15
thank you
Thanks for sharing sir
Helped a lot thanks
Maganda pero slow down a bit kasi masyado kang mabilis.
Pero salamat sa pagpapa explain nito ng mabuti.
Pwede siya ipanood sa mga school.
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.
also - only some Methanogens are lithotrophs. Many methanogens (e.g. Methanosarcina spp) use acetic acid or methanol as substrates for methanogenesis.
The gnome project?
Sir you are best 🤗😇
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.
thanks for make this -.-
How can I dowload your subtitle???
You can copy and paste it
Nice video
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
awesome
what is LUCA?
It's funny how incredulously fascinating this is while stoned off of your ass
Dr. Anderson needs to give us a little bit more information on the assertions he makes. His comments may be true or else may just be assumptions .
So how are you supposed to save the soggy jell like cute beings
'Eukaryote' or 'eukaryote'?
'Prokaryote' or 'procaryote'?
Both are correct, but they came from the Greek word "karuon", so using a k is more common.
Can we use electricity to kill archaeas?
Thanks alot :D
thnkuuuu........
MUITO BOM, BEM EXPLICADO. THANKS
اتمنى كتابة الترجمة لو سمحت
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.
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.
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.
My english teacher made me Watch this
final fantasy 15 brought me here
liquid cyberpunk dude how 😅
Metal gear solid 5 brought me here :p
There is no common ancestor
PERFECT! get a bottle of methanogens and pump in some co2 and use the methane as fuel
free fuel for marsian colonies
Mr Aaaanderson....
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
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.
@0 seconds in and WRONG, TWICE, about the most fundamental issue. They are NOT Archaea Bacteria, they are Archaea PERIOD FULLSTOP. Bacteria and Archaea are two distinct kingdoms, not forms of one another.
god I'm so confused
Makes*
Exactly what I think every time =p
Matrix!
Who cares about being condscending. He's just fucking wrong. It's sad when commenters try to confuse students on learning videos.
From these video am not going to these white teacher
Complete bullshit he's maked all things fully confused
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!
thank you
