Crocodile self reproduces, scientists in awe

Crocodile self reproduces, scientists in awe

Sounds like a science experiment, but it's actually a trait called, 'self reproduction'.

We've heard of plants and certain species being able to reproduce without a partner. 

But the concept still seems quite contrary to what we are taught about reproduction. Nevertheless, asexual reproduction is said to be common amongst plants, insects, birds, fish and other reptiles, but never crocodiles. 

After a crocodile from a Costa Rican zoo laid eggs in 2018, without being in contact with a male, it peaked interest amongst scientists and researchers. 

"She produced a foetus that was 99.9% genetically identical to herself. The phenomenon of so-called "virgin birth" has been found in species of birds, fish and other reptiles, but never before in crocodiles." (BBC)

This is a huge discovery as scientists are saying it could give a peek into the crocodile's ancestors, dinosaurs. They believe that the 'self-reproduction' trait could be an inherited trait from the extinct dinosaur.

The research surrounding the American crocodile's egg from 2018 was recently published in the Royal Society journal, Biology Letters. 

Out of the several fertilised eggs that were laid, one had a fully formed stillborn. It was this foetus that was poked and prodded on and revealed a 99.9% genetic match to its mother. 

All this after the crocodile was not in contact with a male crocodile for 16 years.
