Namibia Sponge Fossils Are World's First Animals: Study

Namibia Sponge Fossils Are World's First Animals: Study: Researchers delve into the Namibian National Park have discovered fossils of sponge said first animal, a discovery that may encourage the emergence of millions of animals in my life years ago.

Tiny fossil creatures vase forms were found in Etosha Park in Namibia, National and other sites across the country in the rocks between 760 and 550 million years, a group of 10 members of the international researchers said in an article published in the South African Journal of Science.

This means that animals that are believed to have originated from 600 to 650 million years, in fact, occurred from 100 to 150 million years ago, according to the authors.

It also means that small hollow balls, the size of a speck of dust covered the holes that allow fluid to pass into and out of their bodies, were our ancestors, says co-author Tony Prave, a geologist at the University of St. Andrews in Scotland.

"If you look at the tree and the projects in this place where you have what is called a group of the stem, the ancestor of all animals, then yes, it will be our great-great-great-great-grandmother," he told AFP.

Prave said evidence that the animals become fossils 760 million years fit into what genetics have suggested looking at the "molecular clock" to measure the average age of a particular kind of looking at the percentage difference between the DNA of another species.

"The aspect of this is quite satisfactory, at least intellectually, is that generally in line with what geneticists would say, based on a study of the molecular clock, when we should see the first appearance of a large multicellular forms of life,"
