@trenddvids: The chicken on your plate is one of the closest living relatives of Tyrannosaurus rex, but thousands of years of selective breeding have dramatically changed it. In 2008, scientists analyzing preserved proteins from T. rex fossils found similarities that reinforced the evolutionary relationship between dinosaurs and modern birds, with the domestic chicken among their closest living relatives. But the modern broiler chicken is very different from its ancestors. Over decades, selective breeding has produced birds that grow much faster and reach market weight in a fraction of the time required in the mid-20th century. This rapid growth has improved production efficiency but has also raised concerns about animal welfare. Research has shown that some fast-growing broiler chickens are more prone to skeletal disorders, leg problems, impaired mobility, and cardiovascular issues because their bodies grow so quickly. High stocking densities and litter conditions can also contribute to footpad dermatitis and other health challenges if not properly managed. Importantly, this transformation is the result of selective breeding, not genetic engineering in the conventional sense. Farmers and breeders have repeatedly selected birds with desirable traits over many generations, accelerating growth and feed efficiency without necessarily modifying genes in the laboratory. The discussion also highlights an interesting labeling point. #fyp
