Part 6/9:
In groundbreaking experiments, scientists have manipulated facial development genes in chicken embryos to produce skeletal structures more characteristic of ancestral forms. This demonstrates that with enough understanding of developmental genetics, it’s theoretically possible to revert certain evolutionary changes, effectively recreating features of extinct species. While transforming a chicken into a dinosaur remains far beyond current capabilities, these studies illuminate how complex traits evolve and how much of that process hinges on gene regulation.
