The study showed that 550-million-year-old dormant living organisms knew how to choose their habitats. This was reported by the University of California at Riverside.
550 million years ago, during the Ediacaran period, multicellular organisms lived on Earth. obamus coronatusIt is named after US President Barack Obama. They lived on the seabed and had a strange shape – their soft bodies reached a diameter of about one centimeter and were shaped like a bagel or a donut. They have no living descendants, and so it is still unclear to scientists how they reproduce or feed. Also, the seabed of that period was not like the modern one – it was covered with bacterial blankets.
Philippe Bohan and colleagues decided research spatial distribution of these ancient organisms and two other dormant species: tribrachidium And Rugoconites. These two species are often found singly or in small clusters – apparently their distribution is related only to their reproductive traits. Unlike them, obama was more selective: they are mainly found near relatives, as well as in subregions with old and mature bacterial covers.
“This is indeed the first example of an Ediacaran creature choosing a habitat, the first of a macroscopic animal that can do so. We also don’t know exactly how they did it,” the scientists say.
obamaprobably by a selective larva that prefers places with a thick microbial cover and the close proximity of others. obama. In the future, the authors plan to find out exactly how ancient creatures developed such behavior.
