The avian embryo as a time-honoured animal model in developmental, biomedical and agricultural research.

Summary: Did you know the humble chicken egg is a superstar in science? For a long time, scientists have used bird embryos to understand how bodies grow. Because chicken eggs are big and easy to look inside, they help researchers study how hearts, lungs, and brains develop. Doctors even use the membrane inside the shell to test how blood vessels grow or how pollution might hurt a developing baby. Farmers also study them to learn how temperature and noise affect chicks before they hatch. From medical cures to feeding the world, the bird embryo is a tiny hero in a shell.
