Scientists may have solved one of life's greatest mysteries - the age-old question of whether the chicken or the egg came first. This has baffled us for centuries. However, researchers in Switzerland believe the egg came first. The scientists studied a tiny marine organism that dates back a billion years. They found it can form cellular structures that are similar to animal embryos. Thus, a prehistoric chicken did not need to lay an egg.

The organism was first discovered in 2017. It has offered many insights into ancient life. A researcher said it "allows us to go back in time a billion years". The genetics behind egg fertilization and embryo development were present before animal life existed. This means nature made eggs before chickens arrived. A simpler answer to the chicken and egg problem is that chickens appeared 10,000 years ago, whereas eggs arrived millions of years ago.

Back to the the chicken or the egg lesson.
