The genetic evidence demonstrates that coiling direction in <jats:italic>N. pachyderma</jats:italic> is a genetic trait, heritable through time, and is not a morphological feature reflecting ecophenotypic variation. The two opposite coiling morphotypes appear to have diverged during the late Miocene, and they have distinctly different ecologies. In combination with fossil evidence, biogeography, and ecology the degree of genetic distinction between the two coiling types of <jats:italic>N. pachyderma</jats:italic> strongly implies that they should be considered different species. We propose the adoption of the widely recognized name <jats:italic>N. incompta</jats:italic> for the right coiling morphospecies. The genetic evidence also demonstrates a low level (<3%) of aberrant coiling associated with both morphotypes. The abundance of these aberrant specimens has no relationship with the environment. These findings have important consequences for the use of <jats:italic>N. pachyderma</jats:italic> and <jats:italic>N. incompta</jats:italic> as paleoceanographic signal carriers in polar and subpolar waters.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381137045290539267","@type":"Researcher","foaf:name":[{"@value":"Kate F.
