"The trick is to examine the gene sequences from different organisms to figure out who they [the sequences] identify as their <a href="http://www.livescience.com/47128-shrinking-dinosaurs-evolved-into-birds.html">closest relatives</a>. When you look at a particular gene in an organism "” let's call it A "” we ask if it is most closely related to its counterpart in organism B, or to its counterpart in organism C, and by how much."</p><div><figure><amp-img src="https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280.jpg" srcset="https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_550px.jpg 550w, https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_650px.jpg 650w, https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_750px.jpg 750w, https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_850px.jpg 850w, https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_950px.jpg 950w, https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_1050px.jpg 1050w, https://www.shared.com/content/images/2017/04/tumblr_ngn329J3kh1sq04bjo1_1280_GH_content_1150px.jpg 1150w" sizes="89vw" title="" alt="" height="9" width="16" layout="responsive"></amp-img><figcaption class="op-vertical-center"><cite>The Earth Story</cite></figcaption></figure></div><p><!-- [invalid-shortcode] --></p><p>Previously, the belief was that sea sponge was the oldest known organism, due mainly to its simplistic structure and genetic makeup. </p><div><figure><amp-img src="https://www.shared.com/content/images/2017/04/biologists-have-long-suspected-sea-sponges-were-one-of-the-first-multicellular-organisms-on-the-planet.jpg" srcset="https://www.shared.com/content/images/2017/04/biologists-have-long-suspected-sea-sponges-were-one-of-the-first-multicellular-organisms-on-the-planet_GH_content_550px.jpg 550w, https://www.shared.com/content/images/2017/04/biologists-have-long-suspected-sea-sponges-were-one-of-the-first-multicellular-organisms-on-the-planet_GH_content_650px.jpg 650w, https://www.shared.com/content/images/2017/04/biologists-have-long-suspected-sea-sponges-were-one-of-the-first-multicellular-organisms-on-the-planet_GH_content_750px.jpg 750w, https://www.shared.com/content/images/2017/04/biologists-have-long-suspected-sea-sponges-were-one-of-the-first-multicellular-organisms-on-the-planet_GH_content_850px.jpg 850w, https://www.shared.com/content/images/2017/04/biologists-have-long-suspected-sea-sponges-were-one-of-the-first-multicellular-organisms-on-the-planet_GH_content_950px.jpg 950w" sizes="89vw" title="" alt="" height="9" width="16" layout="responsive"></amp-img><figcaption class="op-vertical-center"><cite>Science Recorder</cite></figcaption></figure></div><p>But with the new research, scientists are hopeful they can use the information to resolve more long-standing controversies regarding the world and how it was formed. </p><p>Can you believe our world started with jellyfish??</p><p></p></div>
