Modern bird eggs have the color

Although the period of the giant dinosaurs has retreated far away, however, their genetic traces are still preserved today.

Most recently, Dr. Jasmina Wiemann from Yale University (USA) discovered the color of modern bird eggs are inherited mainly from Eumaniraptora species and even Velociraptor .

The color of modern bird eggs is inherited from the eggs of some dinosaurs.

In his study, Dr. Jasmina Wiemann pointed out that, normally, the color of bird eggs is formed by the characteristics of the environment they nest and although there are only two main pigments, red and blue, but these pigments proved to be quite effective in disguising birds to avoid the enemy from robbing eggs.

However, the more special problem is in the origin of why the color of modern bird eggs is mainly in red and blue colors. To find the answer, Dr. Jasmina Wiemann studied 18 dinosaur eggshell fossils, searching for the two most important pigments used by modern birds to create a variety of colors.

In Nature, Dr. Jasmina Wiemann said, she studied on many species on two continents. After the research period, it was discovered that Eumaniraptoran's eggs were speckled in a manner similar to modern bird eggs.

"This completely changed our understanding of how the color of modern bird eggs. Previously, for two centuries, bird researchers claimed that egg colors appeared in modern, evolving modern bird eggs. up, ' said Dr. Jasmina Wiemann.

In addition, scientists studying in the same group with Dr. Jasmina Wiemann also said that the color of eggs appears at the same time that some dinosaurs start using open-cast nest , instead of hiding their eggs in the sand. like modern reptiles. This makes the egg vulnerable to attack by the enemy. Therefore, camouflage is essential.
