Insights into our animal ancestry can be gleaned from the discovery of the “world’s oldest meal,” according to scientists.

According to the Australian National University, scientists have uncovered
remains of some of the earliest known animals that date back 575 million
years. This discovery provides insight into the biology of our prehistoric
animal ancestors (ANU). The ANU research team uncovered new
informatInformationhe the early animal ancestors’ physiology by analyzing
fossils from the Ediacaran period acquired from Russia.
The Ediacaran biota, 575 million years old, predates all other animal
groups on Earth. Animals fed on bacteria and algae collected from the ocean
floor, according to ANU researchers. According to ANI, the research
results, published in Current Biology, explain how these peculiar organisms
consumed and metabolized food.
