Reproduction usually takes two parents, at least in most sexually reproductive species. But there's a few different species that have decided to go solo, so to speak. From whiptail lizards to California condors, here are a few of the coolest single moms in the animal world!

So if parthenogenesis was possible in hominids, Jesus should have been a girl ?
It seems that the references are the same as the video about clocks th-cam.com/video/c2VlfnwitH4/w-d-xo.htmlsi=LDzF0cCCpu3Nnmt-
In the video, she said that there would probably never be a mammal discovered that can complete parthenogenesis, but then the explanation clearly stated that this was why placental mammals specifically couldn't do parthenogenesis. Does this mean that marsupials or monotremes could possibly complete parthenogenesis, or is there a different explanation for that being impossible?
@scishow Serious question: Can condors and vultures cross-breed? They look so similar and if Narwhals and Belugas can make a Narluga..... then maybe it's possible for a Conture or Vuldor bird to exist.

I live in the Chihuahuan desert in New Mexico where the New Mexico whiptail is. I see these girls constantly. They are also lovingly dubbed “lesbian lizards” because they sometimes get a little frisky with each other to promote ovulation.

Mourning geckos are really cool, they're essentially lesbian lizards. They can produce young by themselves, but the process needs another gecko to mount them to start the process. Also, it's a female only species

Are they the ones who occasionally have infertile males? Pretty wild
Wait... if female bees kill and eat diploid males, does that mean the bees can tell diploid males apart from haploid males?
If the DNA codes for a pheromone, it would probably change the form of the pheromones if there are extra copies. Nature is wild.
This likely evolved because a haploid male shares 100% of his dna with his queen, while his children would only share 50%, making them loyal to the hive over their own young. Diploid males share equal dna with their mother and their young, making them potential traitors if they left to breed with an outside female
Indeed, the astute worker bees possess a remarkable ability to discern between diploid and haploid males. Let’s explore this fascinating phenomenon:
Distinct Characteristics:
Diploid males exhibit certain distinctive features that set them apart from haploid males (drones):
Size: Diploid males are larger than haploid males.
Eye Color: Their eyes are darker due to the presence of additional genetic material.
Antennae: Diploid males have shorter antennae compared to drones.
Behavior: They often display abnormal behavior, such as being less active or less responsive.
Worker Bee Behavior:
When worker bees encounter a diploid male larva in the brood cell, they assess its characteristics.
If it exhibits the telltale signs of being diploid, they take decisive action.
Elimination Process:
Worker bees promptly remove the diploid male larva from the brood cell.
They may consume it or discard it outside the hive.
This process ensures that valuable resources are not wasted on non-functional males.
Colony Optimization:
Worker bees prioritize the overall health and efficiency of the colony.
By eliminating diploid males, they maintain a balanced sex ratio and conserve resources.
In summary, the worker bees’ ability to recognize and selectively eliminate diploid males demonstrates their adaptive intelligence and commitment to the colony’s well-being. 🐝🔍🚀

I just spent all morning researching the self-cloning (parthenogenesis) Marbled Crayfish to win an argument with my brother… then this pops up. The argument? That these were the crayfish we used to catch in West GA back in the ‘80s and early ‘90s. Had to show that they aren’t yet pervasive except in the streams they’ve been introduced to by humans since being discovered 1995. Obviously, they could exist naturally in one stream somewhere if their origin was not in captivity but it’s not likely to be that one.
Haven't done much research into it, but I have read some of the overviews written about it: correct me if I'm wrong, but wasn't it linked back to the German pet trade? If so, then they had to get the animals from somewhere, and I'd assume that they were just caught and imported from the US.
@@abtinbarzin8369 A German discovered them after buying “Texas Crayfish” from an American pet dealer and noticing the parthenogenesis in 1995. They weren’t even named until 2003. It very well may have come from a wild-caught population somewhere but they would have been isolated, not pervasive, and the distribution map does not even include West GA, meaning the odds that we had them as kids were very low. Because they can’t easily get from one waterway to another disconnected one, all known wild populations were introduced there by people.
That said, I recall a pet shop in town that had a pregnant crayfish (eggs/young under tail). My twin brother and I were literally saving money for it when we found out there were free crayfish in the woods right behind us. :) Most were small but a few were almost lobster-sized! Before you knew it, all of our aquariums had wild-caught crayfish of all sizes… and I never saw a single adult with young. We put that money toward our saving for some Red Eared Sliders (turtles) and by the time we had enough Georgia had made it illegal to sell them due to the possibility of carrying Salmonella.
I’ve noticed a lot of biology videos being uploaded lately! It’s such an intriguing topic!
Someone needs praise for bringing the condors from the brink of extinction.👏🏻👏🏻👏🏻👏🏻
I think we need to distinguish between clonal parthenogenesis and consanguinous parthenogenesis. In the case of cloning there isn't really genetic information lost at the individual level or multiplication of deleterious alleles within an individual.
In the case of consanguinity, then it is almost maximally bad from the standpoint of deleterious recessives.
I guess when the angry man told the animals to "f themselves", they took it to heart.
The word "Parthenon" originates from ancient Greek and is derived from the Greek word Parthenṓn, which means "virgin's apartment" or "maiden's quarters." The Parthenon is a famous ancient temple located on the Athenian Acropolis in Greece, dedicated to the goddess Athena, whom the Greeks often referred to as "Parthenos" (meaning "virgin" or "maiden").
The connection between the Parthenon and the concept of virginity stems from its association with the goddess Athena, who was regarded as a virgin deity. The temple served as a monumental shrine to Athena Parthenos, embodying her role as a maiden goddess and symbolizing her purity and wisdom.

Ok so 7 is mammals but you only covered placental mammals. What about monotremes, where no placenta is formed?
I bet the cell tagging is still a thing.
they probably would've given them an honorable mention if there had been any documented cases
There is only the two monotremes, the echidna and the platypus, and they get their freak on in the standard manner. Well kind of, the male echidna has a 4 headed penis and the male platypus has a 2 headed penis and barbs along the penis so he can stay inside the female whilst mating in the water.
The platypus courtship is amazing to see, they play in the water in sync with each other, yet not touching until the female is ready. Then it's 10 minutes of nooky time and afterwards she ignores him and heads off to her burrow in the bank, whilst he has a rest before heading off to start courting another female for a couple of weeks before he gets another 10 minutes of happy time.
Both are amazing, and beautiful. I'm fortunate to live close to a creek that is home to a few platypus and water rats and other native wildlife.
I'm not so happy about the abundance of nope ropes (snakes) in the area, but they aren't bad eating if cooked properly.

On mammal parthenogenesis: Ovine parthenogenesis has been triggered in a laboratory setting, but this is far from natural mammal parthenogenesis. Great video folks! I would love to see you delve into uniparental disomy next.
Okay, the topic is an awesome choice and the information is presented fluidly and easy to engage with.
I feel the need to comment, however, on how much life that sweater gives me
They are my fav presenter so far!
I was wondering why there weren't mammilian pathenotes.
Also, that's fascinating about the bees. I wonder what would happen if the diploid male managed to mate?
Male bees do not use meiosis to make sperm because they are normally haploid, so they just give their entire chromosomes instead. So if a diploid male mated with a queen it would result in triploid females. Being triploid doesn't work for meiosis and would result in sterile queens. I think it also makes the effects of inbreeding worse, and diploid males are already a symptom of inbreeding, more inbreeding = higher chance of diploid males since it's likelier you get two copies of the same single allele out of the ~15 sex-determining gene alleles, which is what results in a diploid male.
@@DJFracus Interesting; thank you.

Most species of ants are similar to bees, with diploid females, haploid males--but there are SOME species that have thelytoky as well.
I got into a lot of trouble when I mentioned parthenogenesis during a junior high science class and again during a high school biology class. In both cases, the teachers said there was no such thing.

Awww is that Jarvis Johnson merch?
Wooo, it is! 🎉
I have found that black mollies will change from female to male if there a no males in the tank. This takes about a month and the female will have live young.
That's interesting, on the rare occasions we have a smoke I've found that a bit of molly makes my 45 year old wife change into a giggling teenager with the munchies who goes to sleep after about 15 minutes of telling me that we should go out dancing.
Fortunately she doesn't change into a bloke.
The fact that the parthenotes seem to be consistently sickly (in non-obligately parthenogenic) vertebrates is really interesting. Why would reshuffling the mom's genes result in that high of a chance of sickness? And that many KINDS of sickness? If the young aren't viable long-term, why would these animals waste so much energy making parthenotes?
In addition, this issue strikes me as somewhat similar to the issues seen with clones. In short, is there something that parthenogenesis and cloning lack that sex has? (Edit: I mean, does sex do something on the cell/gene level that cloning and parthenogenesis don't have? More than just having additional gene-options)
I mean it's the same problem as inbreeding, except one million times worse
Sex evolutionary is a way to shuffle up genes, and reduce the chances of bad, hopefully recessive genes from expressing. More shuffling increases the chance of something different to activate compared to the parent. Most of the time, a different gene does nothing. Sometimes, its worse and the offspring dies. But sometimes the offspring unlocks something more beneficial, and this increased survival rate spreads out through the population.
Low genetic diversity is a problem because the chances of genetic shuffling is lower, risks of negative genes expressing is higher. If some disease hits a low diversity population, it is less likely any members of the species has happened upon a genetic quirk that increases their resistance, which is why cloned species are especially vulnerable to infection.
On a side note, there's a portion of the European population that is more resistant to the bacteria that cause the Black Death. You can imagine why.
I'm sure there are exceptions where something positive comes out of it and that might be it. Like laying thousands of eggs and hope that a couple survive.
@Appletank8 I get that part, but this video is making it seem like parthenotes are almost guaranteed to have issues, while inbreeding doesn't cause issues as quickly. I mean, just look at the parthenote condors; there's tons of inbreeding going on and yet the parthenotes were particularly weak. (Maybe that's because they were inbred AND parthenotes?)
@@Infernoraptor I guess that if the gene pool is healthy, a few clones won't be much of a big deal, and can add a few more bodies into the population. Like, many monarchs of Europe were inbred but it didn't immediately cause problems until later successive loops. Those female only lizards are healthy now, so a clone wouldn't necessarily come out with issues. But they would be way more vulnerable to environmental shocks.
Is there any evidence that healthier individuals would be more likely to reproduce this way rather than less healthy individuals? It seems like a good way to keep a strong genetic formula passed on
I mean, all sorts of animals regulate reproduction based on availability of resources.

About Mollies, there's a few species you find in pet stores that can change into a male if you don't have any in your tank. Eventually you will have a few.
I've been following Charlotte the ray's story. As of 4/27 still no pup(s). She is huge! They have said that since this is the first known case of parthenogenesis in rays they don't know how long the pregnancy will be. The average gestation period for stingrays is three to four months, so Charlotte is well over the due date for a typical mother stingray.

Exactly, that's how he was born😄
I was really hoping the marbled crayfish would get mentioned. They are a newer species that only evolved in 1988. They are triploid, and their offspring are actually clones of the mother. The entire species exclusively reproduces by parthenogenesis.
They were first discovered in the pet trade in 1995, but we haven't really been able to track down where the first one came from. The species has escaped into the wild in some areas and may become an invasive species. The is especially likely because every individual can reproduce on their own.
RE the tagging thing: methyl groups can be THAT crucial?!? That's epigenetics stuff, right?Isn't that really vulnerable to environmental stuff? That seems really weird for evolution to make the placenta THAT vulnerable to being broken.
I suppose the markers only have to stay intact for a limited amount of time (if they're only necessary for the placenta to develop), and within a controlled environment, so I guess it hasn't been problematic enough to incentivize a more robust solution?
“There’s never been any observed cases of parthenogenesis in any mammal species.”

I feel like the way you said male drone bees mate with "the" queen, it may be mistaken for them mating with their mother. They don't do that. They fly away from their home hive to find queens of other hives to mate with. And because they are far away, they may go to a foreign hive when they get thirsty or hungry, and the host hive workers welcome the guest drone and let them in and feed them ❤🐝🐝

ZZ Offspring sounds like the best goddamned crossover band ever.
SciShow: There will probably never be parthenogenesis in mammals.

There was sperms donated and an angel brought it with a turkey baster (actually a small eye dropper but Big guy was sensitive about that)
what's funny is that if mammals could do parthenogenesis, all the resulting babies would be female - no Y chromosomes available
There are lots of myths in which parthenogenesis happens. To name a couple….
The Egyptian Sun god Ra created Shu and Tefnut from his spit
The Norse Giant Ymir created several gods from his sweat
The Greek Goddess Hera created Hephaistos by eating a flower and Hebe by eating lettuce.

So much new info!
I love the shout out to Madona. Anyone else catch it?

While parthenogenesis is impossible in placental mammals, could it happen in egg-laying mammals? Or do they have the same or a similar form of genetic tagging? And what about marsupials?
so can they actually choose to do that (like any time or place) or not? or is it more like an automatic thing that happens when a male is not present for long enough?
It’s amazing that this form of reproduction wouldn’t be eliminated over time without any genetic variation. And yet inbreeding with any other species can lead to serious deformities or even death.
In species that can do both, it's generally a trade-off. So snails will opt more for asexual reproduction in an environment with few parasites, because the decreased genetic diversity doesn't hurt their survival, but more parasites will cause them to switch to sexual reproduction. And IIRC there's a lizard that's able to colonize new island habitats more readily because all it takes is a single female turning on the parthenogenesis switch.
