Great article at Abby's ERV.

In the second paper, researchers investigated why those other chickens laid blue eggs. Was it the same ERV at the same location leading to the same phenotype due to common descent? OR was it a different ERV at a similar location leading to the same phenotype? OR was it a totally different phenomenon?

The South American and European chickens have the same ERV insertion at the same site, which enhanced SLCO1B3 expression. The Chinese chickens had a different ERV inserted in a different site, but it lead to the exact same phenotype due to again, enhanced SLCO1B3 expression.

So which came first? The chicken or the blue egg?

The chicken.

Twice.

A retroviral infection of an egg or sperm lead to the formation of a chicken (white egg) with the appropriate ERV insertion. That chicken subsequently laid blue eggs. This happened once to give rise to the Chinese blue-egged chickens, and then again to give rise to the South American/European blue-egged chickens.

EVOLUTION!
