Ancient superfood: form of red algae discovered as oldest plant on Earth

Newly found fossils suggest some plants may be hundreds of millions of years older than was previously estimated, including ancient superfoods like seaweed. Doctor Seaweed® investigates! Ancient superfood: what was discovered? What the scientists discovered were thread-like fossils within fleshy, more complex colonies in sedimentary rock in central India. The fossils suggest that plants which resemble red algae were present 1.6 billion years ago, in areas which were shallow sea back then. Swedish scientists say that this discovery could change our timeline of advanced life forming, and make us judge again how long well known ancient superfoods and plants have been around. The earliest displays of life on Earth are over 3.5 billion years old. These life forms were simply single-celled microscopic structures which evolved into bigger, multi-cellular eukaryotic organisms, containing a nucleus and certain other structures within a membrane. But these new fossils could potentially alter our perspective of when we think different cells evolved, especially for ancient superfoods and plants. They were identified as containing parts of chloroplasts, i.e. structures within plant cells involved in photosynthesis. Therese Sallstedt of the Swedish Museum of Natural History discovered some of the fossils herself, and speaking to BBC News, she said they were “the oldest fossil plants that we know of in Earth, in the form of 1.6 billion year old red algae.” Red algae is a form of seaweed: an ancient superfood that’s been getting even more popular in recent months. Sallstedt described the findings as showing us that “advanced life in the form of eukaryotes (like plants, fungi and us humans/animals) have a much deeper history on Earth...
