Wissenschaftler sagen, sie hätten endlich herausgefunden, was zuerst da war: das Huhn oder das Ei

> Some argue the eggs came first – laid by dinosaur ancestors of the fluffy, squawky bird that funds establishments such as KFC. Others have argued a chicken popped out of nowhere and then proceeded to lay an egg.

> And in a study, published in *Nature Ecology & Evolution,* a team of scientists decided to take 51 fossil species and 29 living species and split them into two categories for examination: oviparous (laying hard or soft shelled eggs) and viviparous (giving birth to live young – like us humans do).

> The study found the early reptilian ancestors of chickens were viviparous – they gave birth to live animals and didn’t lay eggs.

> And while both the teams at Bristol and Nanjing University in China noted that animals laying hard-shelled eggs have been one of the greatest innovations, this research is particularly noteworthy. The team explained the research implies extended embryo retention (when the mother retains their young before birthing) was the ultimate protection for this group of animals in particular – so basically, **way back then, birthing a live chicken was safer than laying an egg.**

> Professor Michael Benton, from the University of Bristol, said: “Before the amniotes, the first tetrapods to evolve limbs from fishy fins were broadly amphibious in habits.

> “They had to live in or near water to feed and breed, as in modern amphibians such as frogs and salamanders. He added: “Our work, and that of many others in recent years, has consigned the classic ‘reptile egg’ model of the textbooks to the wastebasket.”

something housed the “chicken,” im with the eggsperts if they say egg, im egg too.
