Sponges are animals that eat tiny food particles as they pump water through their bodies. Sea sponge helps scientists unravel 700-million-year-old mystery of evolution by University of New South Wales Dr Emily Wong and Associate Professor Mathias Francois.

Although sea sponges are classified as animals, they do not have nervous, digestive, or circulatory systems. Commercial Value of Real Sea Sponges . So, that is over 700 million years of evolution. These genes are switched on and off and further fine-tuned by important but hard-to-find regions in the genome. The sponges are living animals that live in the water. Living with complexity: evolution, ecology, viruses and climate change. The first animal to appear on Earth was very likely the simple sea sponge. In a new study published in Science, we found that humans, mice, zebrafish â and most likely the entire animal kingdom â share enhancer regions with a sea sponge that comes from the Great Barrier Reef. What we did Coming in many sizes and shapes, sponge bodies are a loose assemblage of cells held together by a special protein called collagen which is present in all animals. Our study involved a team of researchers from the Victor Chang Cardiac Research Institute, The University of Queensland, The Centenary Institute, and Monash University. Our findings represent a fundamental discovery in understanding the connection between our genomes and our physical traits. Simple multicellular organisms that have successfully evolved to colonise all the seas and oceans of the world, including the deep-sea. O… “We found that similar sequences are deeply conserved all the way from humans to sea sponges. Trying to find enhancers based on the genome sequence alone is incredibly difficult, like finding a light switch in a dark room. UNSW provides funding as a member of The Conversation AU. For instance, if the first animals had guts and nerves, it would mean that for more simple creatures like sponges to … By Frankie Schembri Oct. 17, 2018, 11:30 AM Sea sponges were among the first animal groups to evolve on Earth, but the discovery of new chemical evidence now pegs the advent of … By Frankie SchembriOct. An improved understanding of the genome will also help us understand how animals evolve. Some real sea sponges are still sold today, used for everything from cleaning car and boat exteriors to removing make-up and exfoliating the skin. We started by collecting sea sponge samples from the Great Barrier Reef, near Heron Island. New genetic analyses led by MIT researchers confirm that sea sponges are the source of a curious molecule found in rocks that are 640 million years old. Even though they make up a significant part of the human genome, researchers are only beginning to understand this genetic âdark matterâ. Head of Regulatory Systems, Victor Chang Cardiac Research Institute and Senior research fellow, UNSW. The product of at least 700 million years of evolution, sea sponges are among the world’s simplest living organisms. But other scientists have contended in heated debates that sponges are the great-grand-daddy of humans. So, they went hunting for “chemical fossils,” traces of sterols—steroids with antibacterial properties—to determine when the first sponges started to appear. Researchers have been torn for years over whether sponges or marine invertebrates known as comb jellies were the first type of creature to branch off … Almost all sponges are found in marine environments.
