Great video. One small suggestion: Include the names of the featured scientists (Rob Denton, Katie Greenwald) in the video description along with links to the institutions where they work. That way viewers can learn more about their interesting research. Thanks. Eric
ᎿᏂᏋ ᏊᎲᎿᏣᏂᏋᖇ Actually, the video goes with an interview piece in the Science Friday radio show and podcast. You watch the video, then listen to the interview. They’re companions to each other. The video is also intended to entice you into reading their journal paper.
Gynogenesis? Females that need sperm to reproduce but don’t really use it? It’s to trigger the eggs to fertilize? But possibly not because they do use genes from those species
O don't think so. The main objective of reproduction is to spread one's DNA. Even though the females won't use half of the genetic information like they would if they were of the same species the males will still be successful fathers. It would be a dangerous situation if sperm production wasn't relatively much less energy consuming than producing eggs. Not only one male can impregnate many females but the females gain sperm from many different species
@@angelikaskoroszyn8495 but that doesn't change the fact that this is a single species using the DNA from other species to create it's offspring. Plus it seems like the genes of the mother significantly override the genes of the father, as if the genes are bar bodied.
The video doesn't really explain how salamanders typically breed and how these ones differ. Theres a brief mention of "stealing" sperm but not the most detail. basically, salamanders will have some fun for anywhere from several hours to several days, but it's basically them just rubbing on each other. If the male enjoyed it he releases a "sparmatophore" that is a little bubble of encased sperm and if the female enjoyed it she'll pick it up. So the difference here is, the females who "clone" themselves will pick up these packets without doing the deed I assume. And from different species. So this is essentially asexual sexual reproduction.
They made a lot of interesting sounding statements but did not explain how this actually works and the impact that it has. How do they get the sperm? If they have a mix of genetics, will they have some traits of both species? What determines the number of DNA copies 2-5? When they clone, do they also clone the other species DNA they have? I was hoping to have the process explained to me instead of just" this is weird, we are cool because we are studying it"
Dear SciFri, we are not interested in just the Epidemiology of Salamanders in Minnesota... Your title is misleading. You should have elaborated more on the process instead of just throwing numbers at the audience. There are so Many interesting facts about clonal reproduction that’ll fascinate Science-seekers. But you people choose the shortcut of Clickbait instead. That’s Sad! Disliked!
You need to read about why editors write such terrible headlines. I hate them too. There is some discussions of the problem in these sets of videos: ua-cam.com/video/FY_NtO7SIrY/v-deo.html

as a sci fi writer, this is fascinating
Yeah, that’s sad coz this video is only fascinating and barely Informative about the actual process of reproduction in Salamanders.
@@thewitcher08111 google is your friend
Hisame Artwork, that’s the point mate, I’d rather search Google than wasting my 8 minutes with this Barely informative video.

Margot Robinson, Thanks for the info. But, still I’d rather directly read the paper instead of wasting time on their shows.
So how do they make sure, that their offspring always still keep a set of their own species DNA when they have so many DNA sets from other species?
I'd like to know more about exactly how they reproduce and live.
Exactly 👍!!

kleptogenesis :)
Shouldn't all these species be considered as one since they can reproduce fertile offspring "together" or is it more like genetic parasitism?
That's what I was thinking! It's like a genetic parasite. I'm telling you, sexual selection is like the quantum physics of biology
Species like this and the ocasional fertile hybrid are the living proof that that definition ain't well suited to describe what a species is
@@GandalfTheTsaagan agreed. Species are a weird concept, that needs some reworking. How we'd do that is unfortunately not very agreed upon

Salamanders said men ain't shit and started reproducing asexually 💀💀💀💀💀

Gotta love the edgelords with their sexist jokes in the comments 🙄
Oh look women can't evolve no wonder
no this is a special breed known as the incel... look there's one above me right now

Whoa!!! 5 sets of chromosomes???
watch at x1.25
this is how the end starts
Wrong theses asexuals never change so they don't evolve
@@bignoasted2701 Wrong they have five different dna set can even get dna from different species of salamander.
@@gunjchowwiwat8357 soooo we can agree that this is how the end of humanity starts ?
