The Human Body Hair Of Hair

Humans evolve from apelike ancestors approximately five million years ago. Most closely related to us are our non-human primates such as African great apes, chimpanzees and gorillas. Scientific studies reveal that more similar traits are being share by human and our non-human primates compared to other animals. As human evolve from our apelike ancestors, changes in our DNA differentiate ourselves from our non-human primate. Even though we evolve from our non-human ancestors and share similar anatomical structures and characteristics, we are unique in our own ways. We possess specific qualities and abilities that differ from other species. There is a substantial gap between non-human primate and fully developed human. Here we will discuss

We look back on history to look at the anatomy and physiology of the human to see what it must have been like and compare that to the chimpanzees. Like the chimpanzees humans used to have their skin covered with hair but when it was exposed to sunlight, the hair must have fallen off. Which leads to the question “When did we lose our hair?” (169).

African American women have different types of hair. For example hair can either be course, fine, and medium textures. The way hair is determined its by circumference and the condition of the cuticle. Fine texture has a small circumference and closed cuticle. Coarse hair it has much larger circumference and the cuticle is much more open. They are often broken down into different types of hair such as African Caribbean, Asian, and Caucasian (European). African Caribbean is usually displayed as a tightly curled and often very dark. “African Caribbean hair is almost kidney shaped when seen in cross section.” (Anoymous, 2013) This type of is usual damage easily. Asian hair is usually “often straight and has a tendency to be lank.” They come in variety of colors for example a dark to medium brown. It usually is thick and strong. Then you have Caucasian or European which can be straight, wavy or curly. They are usually from a dark to medium brown and it also can be thick and strong. “The texture of hair can be vary significantly according to hair color and racial type” (Anoymous, 2013, p. 1)

In regards to hair communities there are different patterns of hair textures. Everyone has different DNA, skin color, and of course hair. Hair textures all over the world have different types. This refers to your specific pattern of hair. This goes from one to four and has specialized divisions labeled A, B, C. The first is 1A, which is described as bone straight. 1B is not completely straight and holds a curl easier. 1C has slight waves and is not fully straight. The second category of hair is wavy or “S” shaped. 2A is loose, and beachy; 2B is tighter and more defined. Lastly 2C is susceptible to more frizz with small spiral like curls. The third is curly. This goes to 3A, which has the curl diameter of sidewalk chalk. 3B refers to a curl

So why did we lose our primate body hair? Why did we leave a hair tree lover ancestors behind for naked up right life style? Well it all comes down to location. Due to the previous adaption to walking on the land instead of living in the trees, humans were now out in the broad daylight, with the hot savannah sun beaming down on them whilst roaming on two legs with copious amounts of body hair. With this happening their brains started to overheat which was incredibly dangerous for them in such a deadly environment. So instead of overheating and dying out or

Primates first evolved from the trees of tropical forests, later to the ground. Through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to

There is a circumstance that has beset the understanding of evolution over time that there is no general theory involving primate evolution. Most of the theories are just mere speculation. Over the years, primates like gorillas, chimpanzees, and baboons all happened to have their turn in evolution. It was previously presumed that the taxon of interest happened to have the exact similar physiology and ecology as the analog taxon (Rafferty, 2010).The majority of the first primate species theories have been utilized because they solely share one fundamental characteristic with the hominines with the chimpanzees as the phylogenetic cousins. This paper addresses the different ecological conditions that handled the evolution of primates. It

Primates first evolved from the trees of tropical forests, later to the ground. Through the times of prosimians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to the transforming environments interacting with natural selection, primates developed their own ways to move better (meaning changes in locomotion) with different types of bodies (meaning changes in body configuration).

Oedemas of sexual tissue with extracellular water retention and swellings of the skin of the circumanal, subcaudal and paracallosal regions (Krohn & Zuckermann, 1937; Dixson, 1998a) are observed in many species of non-human primates, baboons being famous for their large bright behinds. We know that this engorged feature has evolved independently 5 times as different tissue areas are involved in each of the species exhibiting the trait (Dixon, 1998b). Multiple independent evolutions of this trait suggests that the exaggerated swellings serve an adaptive purpose. (Tecumseh Fitch, 2011) The possibly quite significant added costs of simply

Apes and primates come in all different shapes and sizes. They all exhibit different characteristics and most importantly different behaviors that separate these different primates. The thing that is the most fascinating is really how similar they are to us. The similarities go past structure, similarities can also be seen in their behavior and how they think similar to a rational human being. Gorillas are the biggest primate currently alive on earth and they are also one of the smartest as seen through Koko the gorilla who actually understands english and can effectively use sign language. Gorillas are truly fascinating creatures that exhibit behaviors

Darwin once hypothesized that humans evolved from an ape like ancestor and that those ancestors most likely originated in Africa since the majority of the great apes lived there. Unfortunately, Darwin’s hypothesis was ignored for reasons such as people (e.g. Europeans) not liking of having African ancestors—not to mention the lack of evidence did not help in supporting such hypothesis. Thus, finding the missing link between apes and humans was of great important—it still is. Thankfully, through extensive research many scientists have been able to determine a clade called Hominin [7]. This clade contains humans as well as their most closely related relatives.

The essay Hair written by Maria Alderich, is an analysis of women during the 1950’s need to conform, rebel, or fit in to societies social standards and the inner conflict it caused in women’s identity. The essay is Alderich’s firsthand account of the females in her immediate family and how they use their hair styles to define themselves and represent their self-identity.

One of the main reasons why we are so interested in the other primates is that by looking at them we can obtain some ideas of what our ancestor must have been like a few millions years ago. Even though, we are not descended from any modern-type monkey or ape, our lineage does appear to have gone through stages in which we were a medium-sized, reasonably intelligent creature with good binocular vision, hands that were good at manipulation and the ability to climb trees. An evolutionary trend in primates involves the development of offspring both before and after birth and their integration into complex social systems. Another trend in primate evolution has been toward a more elaborate brain. In addition to brain size and gestation periods,

As a senior in highschool, one of my future goals is to become either a doctor or an administrator in health sciences. As long as I can remember, I had a fascination with animal documentaries when Animal Planet was very popular. However, then in high school, I was introduced to the Human Body, and it fascinated more than ever. I want to become a doctor because I have the drive to save other people’s lives.

After flipping off the switch to my cheap, red Revlon hair dryer, I took one glance in the mirror and noticed my hair looked exactly as expected: terrible. My dark brown curls were separated, flattened, and all the volume had been suctioned out. My once-voluptuous locks were now dry and brittle noodles. I have never had great experiences with hair dryers. Honestly, how could I? I have fine, curly hair that frizzes at the very touch of my fingers. Some days it looks like a rat’s nest, other days it looks like five rat’s nests all got into a fight over whose nest could look the dirtiest. So let me explain to you the extent of a mess in which I deal with on the daily.
