#Scientists May Have Found the Blueprint of the Human Body at the Bottom of the Ocean
We know that some animals are #bilaterian—meaning they display #bilateralsymmetry—while others are not, but nature is rarely so black-and-white.
A study found that the sea anemone, a member of the #Cnidarian phylum, uses bilaterian-like techniques to form its body.

Scientists May Have Found the Blueprint of the Human Body at the Bottom of the Ocean

Scientists discovered that the brainless sea anemone build their bodies with a technique common in bilaterians... which is what humans are.

"Together, our findings suggest that the temporal decoupling of head and trunk formation, as maximally observed in head larvae, facilitated larval evolution in Bilateria. This diverges from prevailing scenarios that propose either co-option or innovation of gene regulatory programmes to explain larva and adult origins"

Annelid functional genomics reveal the origins of bilaterian life cycles - Nature

Comparative chromosome-scale genome sequencing and transcriptomic and epigenomic profiling of three different species of annelid provide insight into the evolutionary origin of larvae.
