2 Mysteries That May Have Been Solved

Which Came First, the Chicken or the Egg?

In 2010, British scientists concluded that, “a protein found only in a chicken’s ovaries is necessary for the formation of the egg, according to the paper Wednesday. The egg can therefore only exist if it has been created inside a chicken.” Celebrated physicist Stephen Hawking, however, isn’t so sure.

What happened to Amelia Earhart?

Researchers found bone fragments, a mirror from a woman’s compact and a zipper from a flight jacket on a deserted South Pacific island in 2007. All of these items were from the 1930s and made in the United States. They also found the remains of a campsite. These discoveries have led researchers to believe that Earhart and her flight partner lived as castaways before ultimately perishing. When the bone fragments were tested, however, the results were inconclusive.

# 6 states that "only humans and chimps are susceptible to contagious yawning" which is actually incorrect.

Dogs yawn in response to another dog, or a human, yawning. They have even been found to be more reliable in the response than humans are.

The chicken/egg question is easily solved if you believe in the bible. God created chickens, not eggs!

IMHO, the chicken/egg mystery will largely depend on whether you are thinking on a typical bird egg, or in any kind of egss. If one is not limitimg him/herself to your standard bird egg, then just by looking at the phylogenetics it is clear that the egg came first.

I haven't read the British scientist's conclusions, but it really seems a bit pointless if their result is not the aftermath of a deeper investigation focusing in something else. I spent 8 years working with eggs for my doctorate, and there are really issues more relevant and practical, both for humans and the species whose eggs you're studying, than this.

I still think the egg came first, otherwise where did the chicken come from?
