Saved by the last 4 females from "the Apocalypse of this species": The Norfolk Parakeet (Cyanoramphus cookii), also called Tasman Parakeet, Norfolk Island Green Parrot or Norfolk Island Red-crowned Parakeet. WWF maximum cards about Norfolk Island.


C is for...cookii.
"The Norfolk Parakeet (Cyanoramphus cookii), also called Tasman Parakeet,[1] Norfolk Island Green Parrot or Norfolk Island Red-crowned Parakeet, is a species of parrot in the Psittacidae family. It is endemic to Norfolk Island (located between AustraliaNew Zealand and New Caledonia in the Tasman Sea)."


Breed, baby, breed!

"This species of parakeet was down to only 4 breeding females and 28-33 males in 1994, but its population has since rebounded to 200-300 birds. It is only found in Norfolk Island National Park and the surrounding area."

Wrap your brain around this:


"Genetic reconstruction

Two pieces of the human genome are quite useful in deciphering human history: 
These are the only two parts of the genome that are not shuffled about by the evolutionary mechanisms that generate diversity with each generation: 
instead, these elements are passed down intact. 
According to the hypothesis, all people alive today have inherited the same Mitochondria[26]from one woman who lived in Africa about 160,000 years ago.[27][28]
She has been named Mitochondrial Eve. 
All men today have inherited their Y chromosomes from a man who lived 60,000 years ago, probably in Africa. 
He has been named Y-chromosomal Adam."
