species: a breed or race of similar living things capable of having babies.“This changes our view of early human evolution, which is that it all happened in Africa,” Ms Boehme said. Previous fossil records of apes with an upright gait* - found in Crete and Kenya - dated only as far back as 6 million years ago. The question of when apes evolved to walk on two feet has fascinated scientists since Charles Darwin first argued his theory of evolution that they were the ancestors of humans. The findings “raise fundamental* questions about our previous understanding of the evolution of the great apes and humans,” Ms Boehme said.
Unlike humans, though, it had a powerful, opposable big toe that would have allowed it to grab branches with its foot and safely walk through the treetops. Like humans, Danuvius had an S-shaped spine to hold its body upright* while standing.

Brasier, David Wacey, Leslie Timpe, Martin Saunders and Charles H. Reference: “A possible billion-year-old holozoan with differentiated multicellularity” by Paul K. The team hope to now examine the Torridonian deposits for more interesting fossils which could provide more insight into the evolution of multicellular organisms. Scientists were able to study the fossil due to its exceptional preservation, allowing them to analyze it at a cellular and subcellular level. The fossil was found at Loch Torridon in the Northwest Scottish Highlands. “What we see in Bicellum is an example of such a genetic system, involving cell-cell adhesion and cell differentiation that may have been incorporated into the animal genome half a billion years later.” Professor Paul Strother, lead investigator of the research from Boston College, said: “Biologists have speculated that the origin of animals included the incorporation and repurposing of prior genes that had evolved earlier in unicellular organisms. “The discovery of this new fossil suggests to us that the evolution of multicellular animals had occurred at least one billion years ago and that early events prior to the evolution of animals may have occurred in freshwater like lakes rather than the ocean.” “We have found a primitive spherical organism made up of an arrangement of two distinct cell types, the first step towards a complex multicellular structure, something which has never been described before in the fossil record. Professor Charles Wellman, one of the lead investigators of the research, from the University of Sheffield’s Department of Animal and Plant Sciences, said: “The origins of complex multicellularity and the origin of animals are considered two of the most important events in the history of life on Earth, our discovery sheds new light on both of these. Modern single-celled holozoa include the most basal living animals, the fossil discovered shows an organism that lies somewhere between single-cell and multicellular animals. The fossil reveals new insight into the transition of single-celled organisms to complex multicellular animals. Found in the Scottish Highlands, the fossil suggests the evolution of animals occurred at least one billion years ago and may have occurred in freshwater lakes rather than the oceanĪ team of scientists, led by the University of Sheffield in the UK and Boston College in the USA, has found a microfossil that contains two distinct cell types and could be the earliest multicellular animal ever recorded.The fossil reveals a new insight into the transition of single-celled holozoa into more complex multicellular animals.Scientists have discovered the fossil of an organism with two distinct cell types, thought to be the oldest of its kind ever recorded.A billion year old fossil, which provides a new link in the evolution of animals, has been discovered in the Scottish Highlands.
