The researchers named this worm-like creature Ikaria wariootia, and dubbed it the oldest known example of a bilaterian — aka, the oldest shared ancestor of all living animals. "Burrows of Ikaria ...

For example, 75% of human introns are present ... the spiralian genomes reported here retain most of the inferred ancestral bilaterian gene families (8,203 out of 8,756, corresponding to a 94% ...

The newly described Ikaria wariootia was a small, wormlike creature that marked an important evolutionary step between early multicellular organisms and more complex modern animals. A former intern at ...

The creature, named Ikaria wariootia, is a wormlike animal about the size of a grain of rice, and it appears to be the earliest example of the bilaterian body shape that’s common to the ...

When the researchers took a closer look, they found a series of serendipitous ‘copy paste’ errors during bilaterian evolution were to blame. For example, there was a significant moment early ...

The organism, about the size of a grain of rice, is described as the earliest example yet found in the fossil record of a bilaterian. These are animals that have a front and back, two symmetrical ...

NANJING, China — An international research team recently discovered a segmented bilaterian fossil about 550 million years old in China, which represents one of the oldest mobile and segmented ...

Ikaria wariootia was a bilaterian, like today's animals and humans It lived during the Ediacaran period 550 million years ago The Flinders Ranges in South Australia is known for its large fossil ...
