Averbukh Through personal recollections and experiences, we know that there are hundreds of types of animals with a variety of characteristics and ability, but there seems to be one underlying factor that makes each category of primates unique: intelligence. Through the millions of years the animals have roamed our Earth, the environment has gone through extreme changes in climate, geographic features, and inhabitants, meaning that the primates had to evolve accordingly in order to survive. Through the process of natural selection, primates have been forced to make a change to their features which will help them in any given aspect of life such as scavenging for food or building shelters. Intelligence has played a crucial role in the development of lifestyles, with the fittest, most adapted species having the greatest advantage/upper hand. Throughout the Earth’s existence, changing climates and ecological environments have proven harsh on the primates’ existence, so through intelligence factors they were able to develop a mechanism to surpass all obstacles. Natural selection pressures have been active in full swing to allow all the species of primates to adjust to a type of life that fits their essential needs. In the following paper, I will be discussing the evolutionary changes of intelligence and what contributors have helped progress the primates into what we now see in the present day. GRADE I This particular grade is the lowest on the evolution scale, simply meaning that these are the primates who have been around the longest. This grade consists of the lemuroids family, which specifically include true lemurs, lorises and galagos. During the Paleocene era when these species first came to existence, they were very widespread, mostly in the southern hemisphere. In terms of their characteristics they can be easily compared to that of a present day raccoon. They range from 5-6 lbs. and live an average of 20-25 years. 1

Averbukh They usually live in group of 3-25 lemurs, with the females being the dominant partner, which is rather uncommon. These animals are usually fully sexually active by age 3 and are able to produce offspring only once per year with the gestation period being a mere 134 days. Their diet consists of mainly an herbivore type with foods ranging from leaves, flowers, and herbs, with occasional small insects (Duke Primate Center, 1). They spend around 50% of the day on the ground with their tails straight up towards the sky to inform the others in the pack of their location (Jurmain, et al, 2005, pg 153). They also have an amazing vocal array, with distinct sounds for certain events. In terms of the evolution of lemur intelligence, the results are very interesting considering that this animal has a brain about ¼ of a human. One of the most interesting aspects is that of the social organization is the hierarchy that was established within each group. In the beginning, it started out with life being centered on the family which means
