How Do We Figure Out The Sex ... Of A Fossil?
Рет қаралды 84,149
Ай бұрынWe know a lot about fossils, but there's one thing about all those long-dead organisms that's hard to figure out -- their sex. So let's talk about the ways we can try to determine whether those T. rex bones came from a male or a female, and why figuring it out is so interesting!
Correction:
02:23 While female peafowl are more drab than males, the bird pictured here is an entirely different species: a helmeted guineafowl.

@LookatRealNumberesthe peacocks use their train feathers primarily to show off to the ladies. They will 'lek' or find a spot to display, then wait for the females to decide whether they like the show. Peacocks can fly, quite well, and when they have a full train, it doesn't slow them down much. They shed the train feathers each year after the breeding season and grow a new, often even more impressive, set of feathers for the next year. Source: I have owned peafowl for almost six years. I have three peacocks and two peahens. They are currently in full Disco Turkey mode and showing off constantly 😂🦚❤

Other reptiles exhibit a mix of the two traits. So how did it work in dinosaurs? We might not ever know for certain.

I like how the singular they/them has made a resurgence when referring to a singular, unknown person whose gender is also unknown - the he/she / him/her trend that started back in the mid-20th century was clunky - the (s)he experiment during the late '90s and early aughts more so - and the experiments with "it" during the '80s always sound(ed) awkward. I say "resurgence" because, according to the fine folks at Merriam-Webster, the singular, unknown person of unknown gender sense of they and them predates the yet more loudly defended he/she and him/her by multiple centuries in written English, likely longer in spoken.

Any species that have two or more sex can technically be hermaphroditic if a little genetic mishap happens. But on a species level, no, generally speaking vertebrates just don’t do that. It’s more likely that they would have asexual reproduction and just one sex rather than a species level hermaphroditism.
@aliengeo Ай бұрын
Simultaneous hermaphrodites are organisms that, as a species, possess both sperm organs and egg organs at the same time. This can happen in animals as well as other kinds of life, but the animals are mostly ones like snails and coral. No known simultaneous hermaphrodites exist in Tetrapoda, the superclass that birds/dinosaurs, reptiles, amphibians, and mammals like us all belong to. There are intersex variations, however, where an individual displays traits of both sexes (for example, an animal with both male and female coloration), found across Tetrapoda. Sometimes this includes traits of both reproductive organs, but it's not the same thing as a snail where they're both independent structures. Tetrapods have one set of reproductive organs, so the blueprint for "both at once" like a snail doesn't exist. Rather, an intersex tetrapod may have traits of both types in one set of reproductive organs. (Or not, intersex variation is complicated. Many intersex conditions in humans are completely invisible without lab equipment.) So the answer is that we believe dinosaurs were not hermaphrodites because they were tetrapods, and we don't know of any species of tetrapod that is hermaphroditic. But we have photographic and genetic evidence that modern dinosaurs, AKA birds, are sometimes intersex. So a fossil dinosaur could totally be intersex. Unfortunately this would be almost impossible to prove.

Since people in the comments have decided to be goobers, I might as well. Everyone here is just a random collection of atoms that happens to move on its own rather than via outside stimuli. It doesn’t matter how those atoms are arranged in what pattern, so long as you aren’t disrupting the cohesion and stability of another self propelling atom collection for a reason beyond atomic replacement.

You didn't mention it, but don't female humans have wider hips on average, compared to males, in order to give birth?
@bookworm3005 Ай бұрын
It's actually the pelvic outlet, but yes you can tell the difference! And you can tell if the female had given birth during her life, since that further changes the shape of the pelvis. It's really cool!

They didn't mention it in the video because this one is about dinosaurs, but the key here is really the "average" part of that sentence - we just don't have enough fossils to work out what the average is, so there's not a lot to base conclusions on.
@cherriberri8373 Ай бұрын
Keyword is heavily on average. All the bones can do is indicate likelihood as it's something that can be changed drastically based on the hormones or activity of the person. A weightlifter of either sex will literally have an altered bone structure. as said, averages is the keyword. Error rates can go as high as getting it wrong a third of the time.

While in Mammals males tend to be larger than females, in extant dinosaurs (ie birds) it’s often the reverse. And in many species of birds it’s the male that’s the care giver.
@AcidicGothess Ай бұрын
This only applies to some birds like raptors, in fowl it's often the opposite and a lot of others don't have much if any size difference.

Is it a waste of resources, or is it reusing the existing script to bring that information to this channel to both inform a difference audience than those who might have watched the Eons video and generate more funds via ad revenue? If anyone watches here who didn’t watch the Eons video, which based on the comments I believe happened a fair bit, then that information is spreading to a wider audience.

It matters because sexual dimorphism exists whether you like it or not. Females have a uterus, males have testes. Deal with it.

@@ferretyluv no of course, I was not saying that it didn’t exist. The question I’m asking is whether figuring it out for fossils is a useful pursuit. Where does it help us with medicine or archeology? Or is this just a fun little science vacation ‘because we can we will’? And I mean how many species have we found that done have a male/female split? But those species still exist and you have to deal with it. What if we keep trying to give something a sex, but its species didn’t even have one in the first place? Sounds like a waste of time to me. If you can give me evidence as to why needing to know the sex of a fossil is important, I’d be happy to listen. Otherwise I think this is a pretty useless pursuit.
