Solving the 70 Million Year “Gap” in Flower Evolution

The video explores the origins of angiosperms, or flowering plants, which remain a scientific mystery. Fossil records suggest they appeared in the Early Cretaceous, around 130 million years ago, while DNA evidence points to a much earlier origin in the late Triassic, about 209 million years ago. This discrepancy, known as the Jurassic angiosperm gap, is debated among scientists. Some argue the fossil record is incomplete, while others question the accuracy of genetic models. The video discusses the need for more fossils and refined genetic data to resolve this puzzle, which is crucial for understanding plant evolution and its impact on the environment and other species.
