Our ovary blueprint is ancient, according to sea stars

At first glance, bat sea stars, the nubbly, orange, many-footed creatures often found on the seafloor, seem about as far from humans as one can get. Appearances can be deceiving, however. Scientists have found evidence showing human and sea star ovaries share similar genetics, cell types and signaling processes, despite their ancient evolutionary split. The research is published in the journal Nature Communications.
