There’s one kind of herpesvirus that’s specific to one species of primate, and each virus split off from the herpesvirus family tree when the primate split off from its own tree. But of course, humans are a special kind of primate.
Here are the two studies we discuss in this episode:

Hey Eons fam! We’ve seen your comments about how many herpesviruses humans can have and we wanted to clarify a few things. The two viruses we focused on for this episode are the herpes simplex viruses, HSV-1 and HSV-2. But they’re not the only herpesviruses that can infect humans, they’re just the ones we usually call “herpes.” There are actually eight herpesviruses that we’re the primary host of, including the familiar ones that cause chickenpox/shingles and mono. We can also be infected by herpesviruses from other species (like we talked about here), with herpes B from macaques being probably the most well-known (and VERY rare) example. Thanks for watching!
So help me understand this please? We inherited virus infectability when the virus left its mark in reproductive DNA?
Wait, I got an outbreak of a Herpes virus, and it's neither HSV-1 or 2. I got Chicken herpes, well technically SHingles, from Chicken pox.
Weird ,huh ? It's alive ,it's intragrated . It's staying .
Why is it that there was no mention about HS2 before the 1980s? Was it specific to isolated populations?
To the presenter,
First of all, I missed your name on the video & with the subscriptions I have, it's a pain in the behind remembering names of all.
To the point, you are in a very strange speaking speed for me. Too slow at 1X and too fast at 1.25X (my preferred play speed.
Not a complaint. Just an observation. I may just use Eons videos, with you as a presenter, at 1X to sleep once in a while.
"Nah babe, of course I didn't sleep with someone else. I got it from my hominid ancestors."
Dammit, Og! Quit eating spoiled meat!
Lol

🤣🤣🤣
Hell, it's likely you got infected at birth.
When it comes to chimp herpes documentaries, this is definitely in my Top 3
Wait: there are other chimp herpes documentaries?
I need links.
I'm half-hoping you actually have a 2 and 1 in mind because that would kinda be awesome, is there actually more chimp herpes videos out there?

If only Gordon Ramsay has a time machine, this all could've been prevented by him suddenly appearing and stopping said primate ancestor by loudly yelling, "It's raw!"
He then delivers the secret of the lamb sauce and creates a primate lamb sauce cult
Gordon Ramsay, " It's RAW!!, use protection!"
Then adding some famous man of words to explain what raw is lol

Thats, why im here and sub to the channel, always interesting content
I really appreciate this channel's efforts to provide a cohesive narrative while still clearly stating the inherent issues with incomplete theoretical models like this one. It's a fine line that no doubt causes endless frustrations to the channel's research team, and I, for one, would like to thank you.
He did a good job of explaining how science works.
And yet he doesn't mention why we can conclude so confidently that it wasn't sexually transmitted. I have 0 doubt in my mind that that is how we acquired this virus.

You are almost certainly correct. Ridiculous how this video completely glosses over what is BY FAR the most likely scenario, for over a dozen reasons.
Technically they were both chimps no?
@@CodeNameBoomy Neither of them were chimps; one was basically a chimp ancestor, the other basically a human ancestor
That's very interesting! When I studied nursing, there wasn't this information on the origins of HSV (graduated from nursing school in 1996). We knew it was a virus and that it became known as a virus in the 1940s but that was it. It's very interesting to learn origins of pathology to me because it gives more depth to what I already know. I imagine for some, this is less interesting because they may have already learned this in high school biology and consider it "common knowledge". Thankfully, amidst all the madness of our world, we can still manage to do meaningful research and exploration.
Etiology and Paleobiology is always interesting. And you're right. It is quite edifying.
EDIT: After watching the video and hearing that last line, I see why you've done this episode, and right now. Thank you for that.
Yeah damnit, now I’m curious lol. What was it before the edit?
Ps, leave the original so the edit makes sense : )
Its also a good video fot those who think the covid virus is manmade because it couldnt happen naturally. Meanwhile our entire history we have catched things from other species. Just because we might be able to do it since a few decades, doesnt mean we did.

Human Herpes Viruses include HSV1 and 2, as described. But also infectious mononucleosis, chickenpox/shingles, Burkitt's lymphoma, and cytomegalovirus. I'd like to know about those, as well.
Yes, ever since I learned that Chickenpox was a herpes virus I've been far more curious about it too! I'd love an episode on that one as well. (Not an episode OF that one ;-) ).
I really wish these videos were around when I was younger. This is definitely a field of science I'd want to follow! Thank you Eons

How did malaria come to be? It’s lifecycle is so bizarre!
its
Excellent question! That would be a good topic for a video. For those who are so curious that they can't wait to see whether or not it will be picked up, here's a brief summary from what seems like a legitimate website (first thing to pop up on google that wasn't behind a paywall).
www.malariasite.com/history-parasites/
Related to that, I'd like to see a video on the evolution of sickle cell disease (I wrote a paper on it in my undergrad years ago and still find the subject fascinating). Some interesting facts that I recall coming across:
- as a genetic condition, it evolved more than once in human populations (at least three times iirc). It's a case of convergent evolution and typically popped up in areas where malaria was common.
- it's very likely to be something that became widespread in humans only a few thousand years ago. Most likely explanation is that agriculture created mosquito breeding grounds, which made malaria much more common.
The more we learn about the natural world the more likely it is that such life could evolve elsewhere. We have animals and plants here that rival some of the best science fiction concepts tit for tat.
Listen to "This Podcast Will Kill You" it's fascinating.
This would be interesting the weirdest thing about malaria is probably that genetically the lineage malaria comes from the apicomplexa are very strange as they are close relatives of cilliates and dinoflagellate algae, but somewhere along the line they lost photosynthesis to become obligate parasites of animals (with apparently one known exception that shows evidence of evolving from parasitism to co dependence in some animal called a sea grape). Malaria even still maintains and depends on their chloroplasts for non-photosynthetic processes even though they are no longer able to photosynthesize which is why antimalarial drugs are designed to target their chloroplasts as that is one of the few targets they have that has no analog in animals.
What I am curious about is what could switch an algae to switch from producing its own food to parasitism I presume the nutrient desert of the open ocean might be one driver for such behavior since the reaction between iron and oxygen causes iron to precipitate out of the water and likewise Phosphorous is also scarce with the best source being other organisms. I have read some intriguing details about the evolutionary competition between algae for nutrients as algae kill and "eat" each other when nutrients begin to run out. It put a lot more prospective on to why red tides kill it is apparently largely where those massive blooms deplete nutrients and crash they don't do so lightly after all their are lots of phosphorous and iron inside other creatures so evolution favored mass scale poisoning. Malaria like red tide seems to offer a potent example that algae are not passive organisms.

Sars-Cov19 watch this and take notes: successful viruses don’t kill their hosts. Be like HSV: find yourself a nice niche and stick with your species for the next 6 million years.
Honestly, that always left me a little dumbfounded. If a virus kills its host so quickly, it's destroyed its means of transfer and reproduction. So wouldn't it eventually go extinct?
@@WildFyreful viruses technically aren't alive. So there's no real "don't die out" gene. Just a spread. One fun thing we are now playing with are phages also not technically alive. They look like little robots. Deffinately worth a look ^_^
Have you heard of Herpes Encephalitis? Trust me, you DON’T want Sars-Cov 19 to be more like HSV. At least we have a chance at eradicating COVID 19.
@@WildFyreful Yes and they do go extinct. Whatever sweating sickness was it went extinct. Show symptoms and drop dead that day in 1500's and sweating sickness infected healthy young people. Seamed to flair and go away for many decades then stop occurring.
The 1918 Influenza that killed more than WWI of healthy young but not to young adults mainly just went away within two years. I think it more likely it shared DNA with a different strain of Influenza and mutated out of the quickly fatal form though considering how fast it went away. or in this case stoped killing so many. Killed healthy people and let sick and children live because it caused a immune system overload that could only happen to a healthy immune system.
When they kill too many of their hosts they go extinct, but if enough hosts survive or mutate more resistance, the virus might survive as well. Or the virus mutates into a less lethal, and thus more easily spreadable form.
I can’t say I ever wanted to know so much about herpes, but I just can’t stop myself from watching your videos
and this dude is absolutely SHREDDED and sexy af 😍
i had enough corona rn i need a new virus to think about.
I didn't know it was herpes
Lol
Enough Corona? Try switching to Modelo.
Seriously
Or a very old one.
Never in my long life have I seen an individual get as excited talking about herpes, as this guy .
The excitement comes from teaching, not herpes itself.
And herps isn't a shameful thing and it's not even as big a deal as people make it out to be. Half of the people infected only have one outbreak or are asymptomatic. It's also not even harmful or life-threatening for a grown person.
I guess you don't know many med students :)
Methinks he doth protest to much....
@@sammiegirl883 it is a big deal they can't be around kids anymore they can't be teachers and now they have to tell there parents/partner that they have herpes and have you seen the mama that kiss her baby not knowing that cold sores was herpes the virus killed her baby plus herpes LOOKS DISGUSTING 🤮 it's not cute
Humans: MEDICINE HAH!
Herpes: Do not speak that spell on me witch... I was there when it was written
this made me giggle 😂
It actually goes
Do not cite the dark magic to me, witch. For i was there when it was written
There is a medicine for herpes though. Valacyclovir is one. It suppresses the virus.
Never even crossed my mind to think how long the heroes virus has been around but that was so interesting! I’m sure tons of people don’t have a clue. I had no idea it went back so far.
It's a common misconception that HSV-1 only causes oral herpes and HSV-2 only causes genital herpes. Either one can affect either area. It is just more common to have one type over the other in each location.
Source: I have "HSV-2" from someone with HSV-1, my diagnosing doc said they are the exact same virus
LoveTrueMusic1 They are different strains of the same virus... Also, having it doesn’t mean you know anything about it, just saying.
The video does state that already.
Then what is the real distinction between the two, if that isn't it?

@@robertstuart480 not everybody has worked that out.
@@robertstuart480 Or lobsters. I mean there was a time when ppl didnt' know the only way to cook them is to boil them alive.
Isn't it the same with lice? Headlice are only distantly related to pubic lice which are closer related to Gorilla lice as far as I've heard.
This is exactly one of the reasons that it's way more likely herpes was sexually transmitted. There are even "scientists" who will deny that pubic lice was sexually transmitted from gorilla ancestors! How they can do that is beyond me.
I love PBS Eons, great hosts, straight to the point, super informative no BS. Like for instance in this video, right from the start it dived right in the topic. In 9:30 there are a tremendous amount of education & information there presented in a crystal clear way, thank you.
I am watching this while my herpes on my left lip are reoccurring. Thank you my ancestors for this gift.
You have culture in you,congratulations
I highly encourage you to look into the nutriceutical L-lysine. Making sure the lysine to arginine ratio in your tissues stays slanted in favor of lysine, you can make conditions ungood for replication of the virus, and thus keep it dormant and control outbreaks. If anyone has other illnesses or anything they should check with a physician before use of lysine, but it's generally safe and healthy for normative individuals since it's just an amino acid (another option is looking up and eating lysine-rich foods but I prefer to use supplements). I picked up oral herpes as a little kid and have used lysine to prevent outbreaks (with essentially perfect effectiveness; I only ever get outbreaks when I'm super stressed AND have been off my lysine for at least several weeks, so I go years at a time between breakouts) so it's been well over 20 years for me, and I can't recommend it highly enough. It's a cheap, generally safe, generally effective therapy for preventing replication in I believe the whole herpes virus family, and other viruses too. I hope more people look into the benefits of things like lysine and other legit evidence-supported nutriceuticals.
@@ItsAsparageese Triggers for me are chocolate, peas, beans and nuts - arginine rich foods. Remedy - Acyclovir cream.

HSV-2 doesn't work like that. This one involves "Lil' Willie" being poked around in places it shouldn't have been.

@@LeatherNeck1833 Uh, did you watch the video? At all? It's the case today, but it wasn't back then...
@@KuK137 given the humans tendency to stick little willy anywhere it will fit (of both sexes), the genital herpes virus could just as easy the have followed this path...

"This has been happening to us and our ancestors for millions of years. And we are still here."
I’ve been with this channel since the beginning and I swear that every time Blake hosts he’s built like 20lbs of muscle more than last time.
Really interesting segment, thanks for the education.
I haven't seen an actual comment like this since 2013.
This is the best-structured one yet! I especially liked the discussion about hypotheses and how much of this information we can be confident in. It would be nice if each video ended with an overview of how these studies supplement each other, and why we can trust the science.
Too many of my friends will dismiss an entire topic because some of the downstream hypotheses are untested. It's important to teach people about how we know what we know and how much confidence we can have in this information.
For example, can we be sure that Paranthropus Boisei was the hominin that transmitted HSV-2 to our ancestor? No, but it's not unlikely and it's a hypothesis based on informed calculations.
Can we be sure that HSV-2 crossed species AFTER our last common ancestor with chimps? We can be fairly certain here since the science is robust, and the genetic data is clear.
Critical thinking can and must be versatile.
Great job once again!
Great Speech Training! Absolutely PERFECT speed, emphasis and pauses. All of EONS speakers, always hold my attention perfectly!! And Thank you also for such great educational content... So Right ON!!!
Your team pulled through with covering this topic and many people I know are so glad Eons shared this information with us! Thanks so much to your work and many efforts to putting this segment together for the general public! I shared this video everywhere I could. I have seen every video posted and must say I'm hooked on this channel!
Thank you for not just specifically talking about Covid 19! That’s all these educational channels are talking about and it’s getting annoying.
Thus the case is made to continue funding basic research science, upon which the medical knowledge that will defeat COVID-19 is based.
0.003% death rate in my province. Very scary #... haha. When you have a tightly packed population of unhealthy smoking alchoholics that dont care about hygiene you're gonna have a bad time. Especially if your nation is obese.
The harsh but truth is that we should not. Its in our best interest as a species to carry on without those weak to viruses.
I dont want it to be me or my kids that is sacrificed, but the logic is there.
We are about to find out with Sweden and a few other countries having very relaxed restrictions. They are getting hit now, but claim that the rest will be hit repeatedly and we are only drawing it out.
@@GDKLockout Of course we are, that's the point: not overloading the healthcare system, because:
1. It causes the virus to spread even farther, which can result in a mutation.
2. It makes other medical emergencies more deadly, because of the aformentioned overloading of the healthcare system.
The point is to prevent deaths, not to sacrifice as many people as possible.
If sacrificing the "weak" were a good thing, may as well dismantle every hospital and let natural selection do its thing.
@@joshmarden9933 Or if your nation has a lot of old people living close together, as is the case in Northern Italy.
This is honestly the best channel on TH-cam, I love all the presenters but Blake feels like the cool fun teacher from school I never had.
"The virus could have been transmitted by mating, which I'm sure has crossed your mind" Yeah, no, we haven't been giggling like 12 year olds for the past 7 minutes, nope XD
Very interesting! Thank you for this video! One thing I might recommend for a video topic would be the evolution of vertebrate eyes, especially colour reception! Humans are quite unusual in being a tricolour vision mammal, and birds have done their own thing for a long time.
And we are still here!
Thanks Eons.

Salmen then you just jump in with your mating display.. 💃
....yea. Same.
I've heard the the herpes virus resides in nervous tissue when its dormant so maybe the original infection may not have been merely from eating a proto-chimp but from specifically cracking a skull open and eating brain tissue? It's a bit of a stretch but it could increase the time of virulence of a carcass.
It doesnt reside in brain tissue tho but in sensory neurons in the spine
@@user-ow7fc4wi5k trigeminal nerve*
Since you need a high enough viral load to get infected with any virus, I'd say it's far more likely it came from an active infection rather than a dormant one. I'm not even sure dormant herpes spp. viruses are contagious, although assymptomatic shedding is a possibility.

That stock photo of a person with a cold sore is a pipe dream. If you don't catch them before they erupt and begin treatment immediately (like, hours, not days) then they may only look like that. If not, you're in for a miserable week to week-and-a-half. I've had an outbreak that covered almost a third of my mouth had blisters. It was so painful that I could barely eat or drink because I could barely open my mouth. These viruses really, REALLY suck.
what I do when I get the blisters is I pop them with a sterile needle and rub it with a cotton pad with salicylic alcohol. It disinfects the wound and dries it up nicely and it's gone the next day.

So how old is Malaria? It would be fascinating/terrifying to learn about mankind's worst enemy, unless there's already an episode about it that I forgot about
"This podcast will kill you" has a very good episode about malaria. They trace its history but don't talk much about our ancestors
The first evidence of malaria parasites was found in mosquitoes preserved in amber from the Palaeogene period that are approximately 30 million years old. Human malaria likely originated in Africa and coevolved with its hosts, mosquitoes and non-human primates.
You mean Pangaea
@@SusanKay- I had malaria or as we call it "paludismo", it ain't pretty. Don't have any sequels so I'm lucky
Thank you for explaining the difference between HSV-1 and HSV-2!!!!! People confuse cold-sores with genital herpes all the time.
Knowledge is power!
but both can also cause the other kind of sores
You folks @EONS are seriously intelligent. Thank you so much for all your videos. And you make it user friendly for mediocre IQ like mine .
Excellent presentation of a complex subject. Thank you.
More virus histories please! ❤️
This is a very interesting representation of the viral history. Thank you for this video!
I am really amazed how well made this video was. Sincere thanks and appreciation from your biggest fan in Syria❤️
And there's HCMV, which I learned about last February. "Human cytomegalovirus (HCMV) is a beta-herpesvirus that causes lifelong infection in humans. HCMV has a prevalence of 55-100% within the human population, depending on different socioeconomic and geographical factors."
My partner already had it and it flared up on him in late January 2020 and nearly killed him. He ended up spending almost all of February in the hospital as a result (which also meant that we were already quarantining in March to give his immune system time to recover - lucky for us). Normally, it's a harmless virus that most ppl will never even know they have. But for immune-compromised ppl like my partner (kidney disease), it can be deadly.
Really cool watching this again after doing my hominid evolution lab in university a couple weeks ago... I worked with replicas of the exact skulls that you used to represent each species!
The strain doesn't dictate whether you get oral or genital sores. You get sores in the location where the infection takes up residence, which will be in proximity to where the virus first makes its way into the body. This is usually an oral or genital mucus membrane, but it can also be another membrane or a laceration or other wound.
Most infections are caused by either oral-oral or genital-genital contact, so there is a very strong correlation between strain and location. This is not a *causative* relationship, though; it is merely circumstantial to the means of transmission.
my cousin used to get herpes on his cheeks and ears
Me trying to escape the burn and pain of a bad cold sore I currently have via mind-numbing youtube videos and I click on this one. I now know who to blame for this awful discomfort other than the person I shared lip gloss with in high school.
This video sent me back to looking as all the other videos you did on human history and hominids. You should make a poster of the different early human species that led up to us! I’d buy that
Ok, but the ending to their videos always gives me chills.
"A hominid handling the butchered remains of a primate."
Hmmmmmm. Or interspecies loving..
It could have been both 🤢
It is far, far, far, far, FAAAAAR more likely to have been our ancestors getting freaky with proto-chimps. Not even close. You're more correct than most of those "scientists" cited in the video were.
Thankyou sci show! I find this vid very comforting! It encourages me that one day we will get back to our humans lives when we finally get this virus under some sort of control.
Always informative, thank you.
Rewatched this because I have been dealing with a cold sore for the past few days. Luckily it's getting much better. Can't remember the last time I had one, but know it's been years.
Its crazy that even with the amount of knowledge we have acquired. We still have much more to learn.
A brilliant educative explaination. Thank you
This is one of the best channels on TH-cam:).
Hey Eons, you guys should do a video on strange prehistoric animals like hyenadon or enteldtont and how convergent evolution played a role in their strangeness.
Mating transmission never crossed my mind...
Even though the virus is known to cause venereal disease now?
Me neither lol
It's not surprising when you consider that humans' recipe for survival is "if you cant beat them, join (mate with) them"
Awesome video! Thank you, for sharing. 🙏🏻😃
Great video as you have us accostumed to. I'd like to add, that maybe herpes wasn't so mild at the beginning. Many infections when they're starting to get from one species to the other (stages 2 and 3), many times are lethal or very morbid. Then, if they pass on to other stages of transmission till the moment we have full horizontal transmission, they tend to coevolve and become less virulent, who knows if even beneficial. Congratulations and thanks for all your efforts!
From my study, I know there are 6 or 7 herpes viruses that can infect humans like chicken pox, CMV, HSV1 and 2.
What is the full story I would like to know.
And thanks for this video, It keeps me interested.
Wikipedia says there are nine herpesviruses that infect humans. The most famous is _Varicella zoster_ , which causes chickenpox and shingles. This video seems to not actually be about the whole family of herpesviruses (called _Herpesviridae_ ), but specifically about the _Simplexvirus_ genus. There are only two of those viruses that infect humans, called _Human alphaherpesvirus 1_ and _2_ , though usually they are called "herpes simplex virus 1" (HSV1) and 2 (HSV2). I wish they had made that a little clearer.
This is so interesting. I know its a hypothesis, but I've always been curious how diseases "started"
Its weirdly comforting to know that this virus is so old and not some "new" thing. Honestly, it made me cry.
You are lovable!
Wow, this presenter is by *far* the most interesting one I've seen on PBS. Thanks to him a million-fold! Further, his hundreds of hours at the weight machines make him look so healthy and fit. I love the effect and am jealous. Girls probably go ga-ga over it. Altogether, this was a good video, wonderfully presented by a world-class speaker. Thanks so much.
Me watching this rn with a cold sore 👁👄🔴👁
@@morphe42 😂
Payton Richardson yup... upper lip annoying...
Lmaoooo I hate cold sores. When I was younger I used to get the biggest ones on my upper lip and it hurt so bad that I couldn’t even go to school or eat.
cold sores or canker sores?
Great video guys as always!!! Keep up the good work!!! Love paleontology. Dont forgot the 2 evolutionary history epsiodes: the pinnipeds and tyrannosaurids
Great Video! thank you very much!
This was amazing!
I thought that was gonna be about Virus DNA in ours, but this is much more interesting.
Me too! I heard that we have 2 complete copies but they have yet to manifest.
Can you guys cover the mosasaurs? Cus they are one the only prehistoric animals that has lived all over the world from 95 to 65 million years
Just the thought that STIs exist makes me so stressed😖
Mmmm 😢this is why 😢you don't want to married jbotbergnatorv me you have herpes 😢 I don't care i
it does make you wonder. You guys are great. patrick, jake, jon, sean, steve. you guys rock! love this channel. oh, and the host.... can't remember your name, btw martial arts come in handy too.
Watching this with my mum, she sees the graphic of zoonotic diseases, and goes "aww look at Ebola, it's different"
Impossible. I couldn't have had them for millions of years, I'm barely five centuries old.
ya don't look a day over 3!
4 centuries here.
Lestat, it’s rude to lie about your age. You’re barely over 250.
Hope my comment made you smile.
STEVE YOU ROCK!
I like how the bodymap showed the two visuses were basically just claiming real estate.
Actually, I remember watching something from Sci-Show about curing the common cold through genetic engineering. However, the lab animals that were immune to the common cold had reproductive problems. Hence, the Herpes Virus needs a number of specifically specialized cells that can be found in our respiratory tract & our reproductive organs.
-N’k V’nsable of Princeton, Minnesota…
"Proto-Chimp" seems like a great band name
Your workout is really impressive...
Nice work reminding viewers of science's self updating methods!!!
