The organisms in this Order usually have flat noses and prehensile tails (can hold onto something). They have relatively large brains and evolved to have better sight and sense of feel. New World Monkeys diets consist of plants and insects. They also live in groups called troops. These troops usually consist of a male, a female, and their offspring. The habitat requirements are trees and a water sources nearby.

These are the smallest New World Monkeys coming in at 4.6 - 6.2 inches. Their days consist of mostly hiding from their multiple predators and eating. These monkeys have claws to help them climb trees easily. They hang out in holes they make in trees and eat tree sap or insects (mainly Butterflys).  They are located in the Amazon, Brazil, Colombia, Peru, Ecuador, and northern Bolivia. And live in groups of 5-9.

These monkeys have bald, bright red faces and are intelligent. They live by the hundreds in trees by the Amazon River. The length of this monkey is 14-22.5 inches and has a very heavy fruit diet. To obtain food they branch off of their group of hundreds with smaller groups of 1-10. These monkeys have one child every two years. The slow rate of birth combined with environmental issues the species population is decreasing.

# data[].attributes.body
This is the largest type of New World Monkey that can grow to 52-71 cm (20-28 inches). These monkeys are primarily arboreal and live in Bezile, Northern Guatemala, South-Eastern Mexico, and possibly northern Honduras. Both sexes have a long, black fur coat and a prehensile tail. They live in groups of 4-6 consisting of a male, breeding females, and the offspring. Males that don't have troops fight the males of other troops for the ownership of the group. The loser of this fight usually ends up dead or critically injured.

These taxonomy charts show how my three exemplary species are related because each one has the same identification for 4 out of the 7 groupings. Specifically at the family category they split off.

The three skulls show that primates evolved to become more efficient. The first skull ( Killikaike blakei) which is 16.4 million years old had huge eye sockets. But as you fast forward to 500,000 years ago to the Protopithecus LS and the Protopithecus TBV skulls they have much smaller eye sockets. The decrease in size gives more space for the brain in the skull but the primate still has the same sight. Also the two femurs show that primates bone structure is improving over time with the left one being more recent and having a more defined gluteal tuberosity.

1. Silvery Marmosets have 44 chromosomes

2.  pygmy marmosets have 44

3.  Geoldi’s Marmosets have 46

4. And Squirrel Monkeys have 44 aswell

Sets 1,2 and 4 were very similar because they have the same number of autosomes and sex chromosomes. But the Geoldi’s Marmosets chromosomes had both X’s and a Y chromosome along with a 22nd chromosome that none of the other monkeys have.

Some more evidence of evolution is the anatomy and physiology of the New World Monkeys. The part of the body that evolved was the nose. The nose of a Old World monkey has a thin septum with downward facing nostrils. The New World Monkeys have a wide septum with outward facing nostrils. Both structures have the same functions but this separates a new from an old world monkey.

# data[].attributes.body
New World Monkeys have a certain gene in their X chromosome that affects their eye sight. Because of this female monkeys can become trichromatic. Howler monkeys also carry this gene in their X chromosomes, but in howlers both male and females can become trichromatic. This is proof of evolution because most New World Monkeys are dichromatic or even monochromatic.

# data[].attributes.body
I think the type of speciation is gradual because the monkeys live in large groups. For example the Uakaris Monkey lives in troops with hundreds of monkeys so the gene pool is constantly diverse

# data[].attributes.body
I think that New World Monkeys evolve with divergent evolution because the differences from monkey to monkey are never significant. for example Old monkeys to New monkeys the main evolution was the nose strucure.

# data[].attributes.body
Genetic drift is used in howler monkeys when a male gains ownership of the group after fighting the previous male.
The other mechanism is random mating, this occurs in troops because there is one male and a couple of other breeding females

# data[].attributes.body
Descent with modification: One way descent with modification occurs in the New World Monkeys are the distinct features such as, prehensile tail, flat nose, or opposable thumb that is passed down from generation to generation.
Type of Natural Selection is directional selection because the environment for most of the monkeys is being over run by humans and this is causing many of them to become endangered.
