Seeds have helped plants evolve into a breathtaking variety of forms that fill our world with color and provide us with food and medicine. It's difficult to imagine where plants would be today without seeds. That raises a question: Where did the first seeds come from?
Plants started using seeds to reproduce toward the end of the Devonian period (419 million to 359 million years ago). Scientists are still studying the exact evolutionary origins of seeds, but the earliest confirmed seeding-plant fossils are from the Famennian age, which began around 372 million years ago.
