This is called parthenogenesis and is a known phenomenon, albeit rare in vertebrates. Some species, like the New Mexico whiptail, rely on it (all New Mexico whiptails are female).

Here is a paper from 2007 that talks about parthenogenesis in hammerhead sharks..

[–] VindictiveJudge@lemmy.world 49 points 2 years ago (3 children)

The New Mexico whiptail is also an F1 hybrid. If they go extinct, you can make more by hybridizing a little striped whiptail and a western whiptail. In case anyone thought that 'species' was a solidly defined word.

Ee ah ah ah

Wasn't this also like the inciting incident for the original jurassic park movie?

[–] Khanzarate@lemmy.world 18 points 2 years ago (1 children)

Nah.

That one was dinosaurs changed gender to male, citing the frog DNA they completed the chain with as having that potential.

So what was supposed to be an all-female park to prevent reproduction became co-ed and then nature happened.

[–] Caboose12000@lemmy.world 7 points 2 years ago* (last edited 2 years ago) (3 children)

I'm still confused on the difference

Edit: thank you to everyone who replied, I understand the difference now

[–] Telodzrum@lemmy.world 23 points 2 years ago

Jurassic Park’s version is still sexual reproduction. Parthenogenesis is a form of asexual reproduction.

[–] lakemalcom10@lemm.ee 21 points 2 years ago

Parthenogenesis - egg just becomes embryo, no male required

Jurassic Park - one individual turned from female to male and started making babies

[–] homesnatch@lemm.ee 3 points 2 years ago

One was direct development of an egg into an embryo, the other was conversion of an animal from one sex to another to facilitate mating.

[–] StalinIsMaiWaifu@lemmygrad.ml 8 points 2 years ago

No, in Jurassic Park African frogs are used as the genetic gap filler, these frogs (and therefore the dinosaurs) are able to change sex in same sex environents

Genomic imprinting says no. It wouldn't produce a fetus that is in congruence with the possibility of life. It could at most start growing and developing, but it would die in the womb. More akin to a tumor than to a baby.

How comes it's possible for a bird or a fish, but not a human? If this article explains why, it is a bit obscure for non specialists.

[–] Gormadt@lemmy.blahaj.zone 12 points 2 years ago

No worries the whole concept of parthenogenesis is a really obscure and obtuse one.

Here's a SciShow link that does a really good job of describing it in a less obtuse and confusing way.

[–] mexicancartel@lemmy.dbzer0.com 4 points 2 years ago

Good to know. Didn't expect a serious reply

[–] DaMonsterKnees@lemmy.world 3 points 2 years ago

And with our votes combined, we will push this good scoop to the top! Thanks, friend!

[–] Xavienth@lemmygrad.ml 3 points 2 years ago

Interesting fact about the NM whiptail, they still need to have sex to reproduce for some reason, despite no gene swap occurring.

One of the three wise men is among us! He's seen the signs. Now he must go bearing cans of tuna and gold doubloons.

[–] Revan343@lemmy.ca 37 points 2 years ago (1 children)

It's only shark Jesus if the baby is male, because that would be a miracle. If the baby is female, it's just parthenogenesis

[–] AngryCommieKender@lemmy.world 8 points 2 years ago

So we need to rebuild the Parthenon?

“All female shark tank” is my new band name.

Owner has some explanations to do.

What? I have already told you that I love sharks from the beginning!

[–] Toes@ani.social 13 points 2 years ago

I'd like a DNA test to confirm they aren't half human.
