Yes, you heard us right, a female crocodile had a virgin birth after being isolated for 16 years. Now, crocodiles sometimes lay eggs anyway, without any male input, but the amazing thing is that one of the eggs was fertilized somehow. This process is called "parthenogenesis" - in which a female fuses its eggs with polar bodies — small cells containing chromosomes, which can generate a viable embryo. However, the egg is a 99% match to the mother, which makes it an interesting evolutionary advantage.

Although the hatchling didn't survive for very long, it suggests interesting theories about dinosaurs. With this recorded event, scientists are speculating that dinosaurs could also self-reproduce, which is basically the whole plot of Jurassic Park.

    Dog - SCIENCE For The First Time In History, A Crocodile Gave 'Virgin Birth' By Laying Eggs Without A Mate

    Well, we can go home and say that we learned something new today. If you already knew what parthenogenesis was, hats off to you. That's probably the biggest word we've said in a long time!

    We're no expert on crocodiles (RIP Steve Irwin), but she just looks like a normal crocodile to us. It's crazy that she was able to make a 99% identical clone of herself…all by herself!

    Font - The crocodile had lived by herself for 16 years before laying 14 eggs in her enclosure. Zookeepers were shocked to find that some of them were viable.

    Font - And while female crocodiles can lay sterile eggs, the zookeepers were shocked to find that at least seven eggs were fertile, ABC News reports. When they put the viable eggs in an incubator, only one continued to develop but eventually stopped. The zookeepers later opened up the egg to find a well-formed, stillborn female crocodile. With news that a female crocodile laid a viable egg without a mate, researchers began investigating.

    Font - In a virgin birth, a female fuses its eggs with polar bodies - small cells containing chromosomes. Typically, polar bodies are byproducts of eggs dividing during reproduction and simply wither away. But in animals capable of parthenogenesis, the polar bodies fuse with the dividing eggs, making the foundation for a viable fetus. The research into parthenogenesis in crocodiles also revealed interesting hypotheses about the ability of other, long- extinct animals to asexually reproduce.

    Font - "This new evidence offers tantalizing insights into the possible reproductive capabilities of extinct archosaurian relatives of crocodilians, notably the Pterosauria and Dinosauria," the study detailed. Given the asexual reproduction ability of birds and crocodiles, it is likely that their common ancestors — dinosaurs and pterosaurs - possessed the ability to reproduce asexually as well.
