baby komodo dragons

It’s Zoo Lovers Day!

My family had a membership to the local zoo (and aquarium) growing up, and it played a huge role in my love for animals and eventually a career in caring for them. Zoos play a huge and incredibly important role in species conservation and protecting the planet as a whole. From education, species survival plans, research, and the like, zoos are making a different in the world and I am so grateful for them. Want to know more? Just ask!

it would be worth having a baby komodo dragon just so you could let them bask atop your screen and then casually introduce them as your monitor lizard

...wait, I'm sorry, mammals are capable of parthenogenesis? As far as I was aware the only animals capable of pulling that off were that one species of lizards and some species of amphibians.

No. At least not in the way that leads to viable offspring. 

While parthenogenesis is actually a lot more common than people think: A whole bunch of insects. Like a fuckton of them, I can’t even name them all, but popular examples are aphids, worker bees (as in, unfertilized females bees), as well as several ant species and that’s just the start of it. Insects are *really good at this*

Aside from that, we got parthenogenesis in crustacean (here, here, here) at least one species of velvet worm (here), two species of flatworms (here) and a whole goddamn bunch of reptiles. Like so many reptiles. I’m just going to leave a bunch of links for several different snake species (x, x, x, x, x,) komodo dragons (x please ignore the absolutely horrendous headline it’s just about the fact that this is a nonsexually produced viable komodo dragon baby), a whole lot of lizards (x, x,) a whole damn lot of amphibeans the point where they got their own wikipedia subpage, at least 3 species of sharks (here, here, here) and at least some birds. We have proof of parthenogenic reproduction in turkeys (here) and chickens (here, takes some scrolling also has numbers on the turkeys)

It should be noted that in birds, parthenogenesis occurs in so far as that ‘eggs starts to develop embryo’ but the vast majority of those embryos never hatch. It’s not so much a method of reproduction for them as much as a accident of reproduction.

Now, mammals… mammals in the wild do not exhibit parthenogenesis. At least we’ve never found one. In lab conditions, people have managed to induce it, but the absolute vast majority of these embryos never go anywhere. They die because the genetic imprinting seems to be fairly important to the proper development of the fetus and it’s not particularly well understood yet (go here

In humans, as far as I’m aware, we’re currently only looking at parthenogenic stem cell lines (again, produced in lab conditions because humans are mammals).

So tl;dr: parthenogenesis is a lot more common than usually thought of, but in mammals we’ve never encountered it outside of very carefully kept lab conditions.
