This small, dark rock is a stromatolite, a sedimentary rock consisting of layer upon layer of oxygen-producing microorganisms. These single-celled microbes were so simple they lacked a DNA packaging nucleus, but were responsible for possibly the most drastic changes the earth has undergone. By producing oxygen as a waste product, they were the only major source of atmospheric oxygen at the time, and therefore critical for the development of more complex life.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSome stromatolites date back an astounding 3.4 billion years, making them the oldest record of life on planet Earth.\u003cbr\u003e\u003cbr\u003eWhen these microbes lived, Earth’s atmosphere had no oxygen, the oceans were euxinic—void of oxygen and rich in hydrogen \u003c\/span\u003e\u003cspan\u003esulfide (H\u003c\/span\u003e\u003cspan\u003e2\u003c\/span\u003e\u003cspan\u003eS).\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Stemcell Science Shop","offers":[{"title":"Default Title","offer_id":31840998948977,"sku":"ST-2220","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0059\/0158\/2449\/products\/Untitled-3_4f9823b6-d94c-4951-8fd3-e4277d21f0d2.jpg?v=1622759018","url":"https:\/\/stemcell.eco\/products\/stromatolite","provider":"Stemcell Science Shop","version":"1.0","type":"link"}
