Primates

Your are going to have to be more specific about the time, and the primates. Certain primates families and groups have been around for longer than others, and some have come and gone, but there have been mammalia concidered in the order primate for millions of years with such evidence as fosils found in the eocene period (35 million years ago)- adapidae for example. Primate groups such as adapidea are no longer living of course. So you must propose a clear question to get a clear answer.

Monkeys have one heart.

The pygmy marmoset has a spine, so is a vertebrate.

The Scopes Monkey Trial garnered widespread attention because it was the first major legal case concerning the teaching of evolution in public schools. The trial pitted the theory of evolution against creationism, two highly debated topics at the time. This clash of ideas resulted in a high level of public interest and media coverage.

Silky sifakas haven't been studied well enough to know their average lifespan, but typically sifakas can live between 13 and 17 years in the wild.

Bonobos

Yes. Males try to mate with as many females as possible.

Continuity advertising is a strategy to keep current customers using a particular product.

yes , it is a type of species and it is a mammal , many beleive humans were enventd from the species of gorrillas as us humans have similarities with these animals

In the wild, mainly trees and foliage, bushes etc. Seeing as apes move a lot to find food etc. I assume they have many different homes throughout their lives, but I'm certain they will always sleep/live in vegitation.

In capitivity, good zoos try to keep their animals in the most similar habitat to the wild that they can get, yet as they place climbing frames and ropes etc. for entertainment towards the animals, I guess they will use that and obviously will use the whole of their enclosure to live in.

The official name for a group of chimpanzees is a troop (or troupe). So if you see several chimpanzees together, they are/part of a troop.

gorillas are the largest of the living primates

Blinking, flinching, etc

There are no 'good' primate dealers. Primates make terrible, terrible pets as they are wild animals, not domesticated at all. If you like your animals peeing on you, attacking your children (and anyone that comes to the door: family, mailman, friends!) with bites that can easily severe fingers and thumbs, huge vets bills (since most domestic pet vets won't take on exotic animals like monkeys), and animal mutilation and cruelty (dealers pull out canines, castrate male animals, cut off bits of tail and remove fingers and toes (to make the animals 'docile' and less agile))...then sure, but you might want to google the horrific injuries people get, the insane costs involved, and the horrific damage you are going to do to the poor animal (even zoos have difficulty getting rid of abnormal behaviours - primates are very intelligent, and will literally run their brains dry, same as a human would if locked in a tiny cage with no entertainment).

Macaques

As primates (apes, monkeys, chimpanzees, gorillas, etc.), are the focus, jobs would be in zoos, laboratories, field investigations, veterinary, etc.

It can be proved by DNA testings on bones. After that you can look at the teeth to find out what they ate.
