The opposite of haplorrine is strepsirrhine
, to which dogs and cats belong.
His research reveals that in the case of marsupials, carnivorans and strepsirrhine
primates that eat harder, tougher and bigger foods have a lesser degree of fusion.
After evaluating 360 morphological features, Seiffert decided that, although the adapiforms shared certain traits with anthropoids--the loss of a third upper and lower premolar, for example--those characteristics had arisen more than once among primates and were "most parsimoniously interpreted as evolutionary convergences" Ida was not a haplorhine anthropoid, in other words, but rather a strepsirrhine
(a group including lemurs and lorises) that "left no known descendants.
Primate jumping genes elucidate strepsirrhine
Only further fossil finds on both continents will unravel the evolutionary roots of so-called strepsirrhine
primates, which consist of lemurs and their close relatives the lorises, the scientists conclude in the Oct.
These ring-tailed lemurs are Strepsirrhines
, a sub-order of primates who share a common ancestor with humans.
Most authors, however, currently favor a distinction between strepsirrhines
