There is no support for their distinct species status from molecular data however.
It did not gain strong support, however, until the emergence of molecular data in the late 1990s.
Whether the three species are truly closely related needs to be determined using molecular data.
Other phyla are included on the basis of molecular data.
In 2006, the family's classification was redefined using molecular data.
Morphological or molecular data so far do not support this division however.
However, molecular data suggest that neither are related to Retiniphyllum.
"Many people would like to ignore this kind of molecular data, and so they criticize it on various grounds," he said.
Molecular data, instead, indicate a closer relationship to family Lemuridae.
Consequently, two new suborders based on molecular data have been proposed.
