Scientists have discovered similarities between humans and ancient creatures that existed more than 500 million years ago. The corresponding article was published on the UCR News website.
We are talking about the Ediacaran biota – a complex of fossil organisms that inhabited the ocean floor about 550 million years ago.
Experts from the Smithsonian National Museum of Natural History studied the fossil traces left by these organisms.
“These animals are so strange and different that it is difficult to classify them as modern living organisms if you look at them,” said paleo biologist Mary Droser from the University of California, Riverside.
The researchers were able to find out that these organisms had rudimentary organs of the nervous system, regulated by the same types of genetic elements that are still used by animals, including humans.
“The analysis showed that the Ediacaran biota could have a genetic predisposition to the development of multicellularity, musculature, and nervous system,” the authors of the study said.
