In the animal kingdom, there are species that carry visual markers for the primitive condition, shown by a common ancestor. In primates, this is noticed largely in suborder Strepsirrhini and they are lower primates. In this suborder, there are four families that I will be primarily focused on: Daubentoniidae, Lorisidae, Galagidae and Lemuridae. These species live in varied locations through Africa, Asia, and Madagascar.
There are selective pressures their environment as documented by Viguier (2002) who found that their physical appearance is affected by the changes in their habitat. The primitive condition in these mammals consists of a few features: their diets are focused on consuming insects, they are small in form and spend the majority …show more content…
There are several species that are still insect eaters and have adapted only for insects. There could have been a mutation in the gut, because there are two families that are able to digest insects and are slightly omnivorous, and in one family they are herbivores to omnivorous. Food sources that are low in quality need more chewing need extended teeth compared to others (Scott 2012). The selective pressures from their habitat could have brought about the need for a mutation in the gut that would allow them to digest higher calorie food …show more content…
The species that tend to grow at a rapid pace, like the lemurs, are those that can process higher calorie food sources (Vinyard et al. 2005). The places that they live vary, as they live from the top of the canopy to the ground level. They can live in different areas or zones, like that of the lemurs on Madagascar, (Martin 1972) and in deforested areas there is a pattern emerging, from skeletal remains, that the central forests were actually a highway to other locations (Godfrey et al
