We specifically explored evolutionary outcomes – i.e. through detailed differences in dental (molar) morphology within and between populations with distinct evolutionary histories – but obviously did not directly study the actual process of selection itself.
This idea was initially based on similarities in behavior and molar morphology, although it gained support with the 2001 discovery of 30 million-year-old Bugtilemur in Pakistan and the 2003 discovery of 40 million-year-old Karanisia in Egypt.
However, we cannot exclude the possibility that molar morphology is associated or covaries with other traits that influenced the sigmodontine radiation.
These and other morphological features are suggestive of an arboreal habitus and, at least with respect to its molar morphology, a rather insectivorous diet.
Likewise, a relationship between family Archaeolemuridae and family Lemuridae has been suggested, based on morphological and developmental traits, yet molar morphology, the number of teeth in the specialized toothcomb, and molecular analysis support a closer relationship with the indriid sloth lemur clade.
First described in 2010, it is placed in the genus Nesomys together with three smaller living species, which may differ in some details of molar morphology.
First described in 2010, it is placed in the genus Brachytarsomys together with two larger living species, which may differ in some details of molar morphology.
Mary Silcox and colleagues reaffirmed the colugo affinities of Dermotherium in 2005 on the basis of detailed similarities in molar morphology.
Molar morphology is illustrated by colored bars on the tips of the branches.
The resulting NPs are uniform in shape and have a spherical morphology with an average diameter of ∼180 nm, in which the molar ratio of Au/Pd is near 75:25 and the catalysts loading is about 0.5 mg cm−2.
