A recent study on algae supposedly sheds light on how aquatic life became terrestrial. So the story goes, "450 million years ago, alga from the earth's waters splashed up on to barren land. Somehow it survived and took root, a watershed moment that kick-started the evolution of life on earth," according to Dr. Delaux of University of Wisconsin, Madison, or, well, any evolutionary scientist. But Dr. Delaux thinks they know the "somehow" now. This is significant, they think, because plants use carbon dioxide and produce oxygen, without which further life could not have evolved. Today, however, photosynthetic marine life like algae and microscopic phytoplankton make up most of the oxygen production, so it is questionable that plant life would need to migrate landward for evolution to move forward for the sake of gas exchange. But one must explain the existence of terrestrial plant life, too! So, as with many evolutionary stories, the scientists and media brush off their hands and say "done" to another major evolutionary hurdle and sprint on toward the next one. But have any of the hurdles been truly cleared? The biggest hurdle that came before it would be abiogenesis. That should've stopped the notion of life without a designer cold (life needs heat ... and a whole lot more than even brilliant scientists and expensive equipment have provided thus far), but it hasn't.
