While we’re at home, trying to fight the coronavirus pandemic and keep the novel virus from spreading, we can learn a bit more about our ancestors.
Experts have just discovered a creature that seems to be our earliest ancestor and also the earliest one of all the animal life out there.
A 555 million-year-old creature is our ancestor
This story is about a tiny worm-like creature that used to live on the seafloor about 555 million years ago.
Experts who are led by geologists at the University of California (UC) Riverside have identified this as the very first known bilaterian – this is an organism with a front and a back as well, symmetrical sides and also front and back openings with a gut in between them.
“It’s the oldest fossil we get with this type of complexity,” UC Riverside geology professor Mary Droser said in a press release.
EcoWatch online publication writes that bilaterians are an important piece of the evolutionary tree that branches out to include the full diversity of animal life.
“This new body structure allowed creatures to move forward purposefully. The fossil was dated to the Ediacaran Period 555 million years ago, when multi-celled, complex lifeforms began to emerge, BBC News explained,” according to the online publication.
It’s been also revealed that other fossils found in the “Ediacaran Biota” are not directly related to the animals that are roaming the Earth today.
Bileterians were reportedly alive dung Ediacaran Biota
Experts believe that bilaterians were definitely alive during the period, but it’s been also revealed that direct fossil evidence was really hard to find.
Experts believed for 15 years that the creatures are the explanation for fossilized burrows found in Ediacaran deposits in Nilpena, South Australia, but it seems that there’s no proof about this.
