indriidae การใช้

Among indriids ( Indriidae ), the toothcomb is less procumbent and consists of four teeth instead of six.
The sloth lemurs ( Palaeopropithecidae ) and monkey lemurs ( Archaeolemuridae ) were classified as subfamilies within Indriidae as late as 1982, but are now recognized as separate families.
Classifications in the first half of the 20th century divided lemurs into three families : Daubentoniidae, Indriidae, and Lemuridae, with the latter including the current Cheirogaleidae and Lepilemuridae.
In 1997, comparisons of repeated DNA sequences within the family Indriidae supported Simon's classification, placing the golden-crowned sifaka as a sister group to the other sifakas.
Although all studies place Cheirogaleidae and Lepilemuridae as a sister clade to Indriidae and Lemuridae, some suggest that Cheirogaleidae and Lepilemuridae diverged first, while others suggest that Indriidae and Lemuridae were the first to branch off.
