Six Evidences Chickens are the Incarnations of Evolved Dinosaurs
Unfortunately, any DNA has long been degraded, but Doctor Schweitzer was able to run tests on proteins in soft tissues. Analysis showed that Tyrannosaurus Rex was more closely related to ostriches and chickens than to any living reptile.
As far as research goes, dinosaurs laid eggs like modern chickens. The fossil record is incomplete, but scientists are fairly certain that all dinosaurs laid eggs. Because if we use T. Rex as an example of the ancestor of the chicken.
Other theropod nests have been found. If T. Rex followed the same pattern. Most of the hatchlings will not reach their first birthday, but those that survive will gain about 771 kilograms. A newly hatched T. Rex would have been about the same size as a modern turkey or locally known as Kalkun.
