Embryology shows that bird embryos start out looking very dinosaur-like. They have long tails, hands instead of wings, and distinct snouts. As they develop, genes suppress these traits to form the modern bird body plan. By using CRISPR-Cas9 gene-editing technology, scientists believe they can inhibit the genes that tell the embryo to stop growing a tail, or to turn the snout into a beak.
Not as they once did. But we may see dinosaur-like traits engineered into living birds, and thanks to paleontological advances, our understanding of how dinosaurs looked, moved, and behaved will be more vivid than ever. For a true, non-avian dinosaur to return, we would need a time machine — not a laboratory. will dinosaurs come back in 2050
Scientists estimate that DNA becomes completely unreadable after roughly 6.8 million years. Embryology shows that bird embryos start out looking
: Even if we somehow found intact DNA, there are no living animals with a compatible enough biology to serve as an egg donor or a surrogate mother to gestate a dinosaur. 🦅 The "Chickenosaurus" Project For a true, non-avian dinosaur to return, we
Scientists have already successfully experimented with bird embryos to produce dinosaur-like snouts instead of beaks, and they are working on growing long tails and teeth.
