Within the face of analysis carried out by the English universities Sheffield and Warwick in 2010, it was found that the formation of the rooster egg shell relies on a protein discovered solely within the chook’s ovaries. That’s, given this info, the egg can solely come after the rooster.

Dinosaur descendants

Animals whose embryo develops inside an egg are known as eggs, in entrance of this group are fish, amphibians, reptiles, monotremes, bugs, molluscs, spiders and birds, reminiscent of chickens.

In line with Charles Darwin’s theories, a species all the time evolves from a extra primitive sort. Because of this birds, like chickens, descended from dinosaurs, which had already laid their eggs about tens of millions of years in the past. Over generations, one species finally ends up giving start to “youngsters” of one other, via mutation.

In line with research, probably the most historic chook is Aurornis Xui: fossils of this animal have been present in China and point out that it already had feathers roughly 160 million years in the past. Archeopteryx is named the “unique chook” within the evolutionary line of dinosaurs.

That’s, the “mother and father” of the hen laid an egg with a chick already in it, and inside it was the hen’s DNA. In line with this idea, the egg would have come first.

This query stays advanced and has no consensus, though probably the most broadly accepted idea is that the egg got here first.

In line with some scientists, the egg got here first and would have appeared about 340 million years in the past, whereas the rooster appeared 58 thousand years in the past.

Nonetheless, if you’re pondering of a rooster egg, the reply is totally different. Rooster (Gallus gallus dominus) has been round for 50 million years. Someday in the course of the domestication of the rooster, it’s believed to have occurred in Asia between 1250 and 1650 BC. The place one of many ancestors of the “domesticated” rooster laid an egg with genetic traits totally different from these of its family.

After puberty, this embryo laid an egg just like the one we’ve got right now. In line with this idea, the rooster got here first.
