Homo Sapiens Evolution
The Physiology and Evolution of Vision from Primates to Homo Sapiens

Bio 392 Mammalian Physiology Denielle Chapman April 14th, 2017

Vision is a way of making sense of the world that, for all mammals, could arguably be the most important sense of the five that we have. For Homo sapiens, the way we perceive the world through our power of sight, came from the species of primates that existed before us according to research done on the skull sizes of primates (Heesy and Ross, 2000). In various species of primates, the ability to observe certain colors within the visible spectrum is not possible but in other it gave rise to the shift of seeing blue …show more content…
The science behind the research can be seen not just in other primates but in us as well and shows how the origins of the mutations that gave us our trichromacy was initially created. It is surprising though just how little research has been done in the last ten years especially since technology has advanced further and could open new possibilities of study for scientists.

    Endless Forms Most Beautiful by Sean Carroll: Chapter 9 Summary

    Jaguars display melanism and the gene MC1R is responsible for pigment type. Specific mutations in this gene allow for all black jaguars. A change in the protein’s sequence, deleting 5 amino acids and changing one into MC1R protein, is responsible for this mutation rather than a genetic switch. Therefore, the ability of pigmentation to evolve without affecting other functions is due to the evolution of the MC1R regulation. MC1R mutations have been able to cause changes in cats and melanic plumage in birds. There are speculations to the selective advantages or disadvantages in some species, but in other species, the speculation is very clear. For example, the rock pocket mice have coloration based on their habitat in order to protect themselves from predators. Light-colored mice are typically found around light-colored rocks, and dark-colored mice are found on dark lava flows. Other examples of melanism include Kermode bears and redheads.…

    Homo Sapiens: A Comparative Analysis

    Families were smaller, due to the fact that the population must stay small. Women and children gathered berries and nuts, while men hunted animals. When agriculture was created there was less hunting so men started to do the women’s jobs.This threw off the balance of equality. More children were forced to do laborious work, and families began to grow. Social classes began to form after agriculture. At this point only two variations of humans existed: Homo erectus and Homo sapiens. These early humans spent most of their days advancing with toolmaking and setting up civilizations around their agriculture.…

    Summary: Key Innovation In Human Evolution

    Key innovation in human evolution is the development of bipedalism and gradual increase in size of brains. The evolution might have occurred due to change in climate and environment which lead to reduction and replacement of trees with grasslands. Due to presence of large numbers of trees, it was easier for our ancestors to have quadrupedalism instead of bipedalism, so that they can climb on trees and move from one place to another. But with the decrease in number of trees, requirement for bipedalism increased. In an article by Wayman E. (2012), it has been mentioned that Lucy had the anatomy of bipead. Lucy belongs to Australopithecus afarensis. It is estimated that Lucy lived 3.2 mya. Her pelvis was broad and she has thigh bones which were…

    Neil Shubin In Your Inner Fish Analysis

    Over decades, many Americans reject the ideas of evolution and there were many arguments against the theory of human evolution. However, in order to understand how the human developed, we must look at the human evolution. For many centuries, we have been curious about our origins and our human bodies structure. How we got to be the kind of species we are today, such as the way we look; walking upright on two legs, our hands has five fingers, the size of our brain and teeth, and what makes us a unique species. Our animal ancestors have shaped our body structure in many ways, we humans have a lot in common than you might think with apes, reptiles and even fish.…

    The Functions of the Eye, Ear and Skin; Their Role in Behavior

    Vision starts with light, the physical energy that stimulates the eye. Light waves coming from some object outside the body are sensed by the eye; the only organ that is capable of responding to the visible spectrum. Eyes convert light to a form that can be used by the neurons that serve as messengers to the brain. The neurons themselves take up a small percentage of the total eye. Most of the eye is a mechanical device that is similar to a traditional, non-digital electronic camera that uses film.…

    The Role Of Vision In Radiography

    There are three distinct layers in the eye with the outer layer consisting of the cornea and sclera, the middle layer containing the iris, ciliary body and choroid and lastly the inner layer which has the retina (Galloway et al. 2006). The cornea’s main functions is to protect the eye against infection and to refract and transmit the light to the lens and retina. The iris controls the size of the pupil, thus limiting the amount of light that reaches the retina. The ciliary body controls the shape of the lens and the choroid provides nutrients and oxygen to the eye. The retina contains neurons that capture and processes light. Light enters the eye via the outer components and travels through the neurons of the retina and is accordingly captured by the photoreceptors present at the back of the retina. The neurons then translate the visual information received from the eye into nerve impulses that travel from the optic nerve to the lateral geniculate nucleus to be interpreted (Willoughby et al. 2010). Each eye sees a marginally different image which is combined in the brain to become one…

    Evolution of Tapetum Lucidum

    The tapetum lucidum is an evolutionary advantage for animals. It enables animals to see in dimmer light than the animal would otherwise be able to see in. The tapetum lucidum is useful to animals, but it also has a use to humans. Human beings use the tapetum lucidum to scan for reflected eye-shine, in order to detect and identify the species of animals in the dark and to send trained search dogs and search horses out at night. Historically, its function was regarded as simply to increase the light intensity of an image on the retina. Using eye shine to identify animals in the dark implies not only color but, also several other features. The color reciprocates to the type of tapetum lucidum with some distinction between species. Other features also include the distance between pupils’ related to its size, the height above the ground; the manner of blinking, (if there is any) and the movement of the eye shine (such as weaving, hopping, leaping, climbing or flying.) Tapetum cellulosum was discovered in the eyes of sharks, sturgeons, and coelacanths, suggesting that it may have been the first type of tapetum to evolve in vertebrates. These species have similar enough tapeta that they may have had a common ancestor with a tapetum developing at approximately the Devonian period or, at the earliest, the very late Silurian.…

    Primate Eye

    In the article Unique Morphology of the Human Eye and Its Adaptive Meaning: Comparative Studies on External Morphology of the Primate Eye written by Hiromi Kobayashi and Shiro Kohshima, there is an extensive look at how the exterior anatomy of primate and human eyes differ, and why this would be significantly adaptive as a trait. The authors focused on the distinctive coloration in the human eye along with its visible unpigmented sclera. They also concentrated their study to analyzing the correlation between eye morphology and the individual’s body size and habitat. The two authors formulated hypotheses relating to these two ideas.…

    Bipedalism

    The life-history of modern human is so different from the other extant apes such as chimpanzee. For example, human has childhood and adolescent before their mature. This should be an adaptive strategy for the expanded and energetically costly brains.The right-handedness shared by both Homo sapiens and neanderthalensis might be a result of the changing in the sensory regions of the forebrain. Nevertheless, it is still not clear whether homo habilis and homo erectus had the same feature. The origin of the human-specific facial expressions is yet in mystery due to the lack of fossil…

    Primate Evolution

    Complex behaviors and intelligence are the trademark of the primate order and this has been attributed in part to relative large brain to body mass ratio (Reader and Laland, 2002). Defining intelligence, however, is a highly problematic issue; an operational definition used points to the primary component of intelligence to flexible problem solving and the ability to cope with any difficult situations (Jerison, 1973). Arriving at an agreement for the driving factors favoring primate intelligence is very difficult. Many theories have been posed as selective mechanisms for the trends toward increased intelligence in primate evolution. Some emphasize complex ecological pressures, mainly foraging strategies as the primary forces driving an evolutionary increases in cognitive abilities, and other suggest that increased social complexity favored the evolution of primate intelligence (Tomasello and Call, 1997). Across the animal kingdom, brain size increases with increasing body size, however, despite the common scaling principle, brain size to body weight ratios differ from one taxonomic group to another (Jerison, 1973; Gould, 1975). In primates, for example, the brains of apes are generally larger relative to body weight than the brains of monkeys, whereas the brains of monkeys are larger than those of prosimians (Jerison, 1973). Structural differences are also apparent. In chimpanzees, a larger proportion of the brain is devoted to neocortex than in monkeys, who in turn have proportionately more neocortex than prosimians (Martin, 1990; Passingham, 1982).…

    eye color genetics

    Eye color is a polygenic trait; this means that multiple genes interact to produce the color of peoples’ eyes, hair, and skin. In the past, it was once thought that a “single gene pair following dominant and recessive inheritance patterns was responsible for eye color, but it is now known to be much more complex than that, involving at least three gene pairs”( Forensic Science International). People have begun to focus on two of the three gene pairs that make the genetics of eye color more understandable. These genes are known as “EYCL1, which is also referred to as gey gene, and EYCL3, also known as bey2 gene. For the bey 2 gene if a person has a brown allele then they will have brown eyes. In the gey gene the green allele is dominant over the blue allele, but it is still recessive next to a brown allele” (Forensic Science International). Another factor that plays in determining eye color is melanin. Melanin is known as a “product of cells in the human body” (National Institutes of Health). These cells create pigments in the body which not only leads the result of eye color but also the color of the skin and hair. According to the Science Education partnerships it says that “light blue eyes have the least amount of melanin and dark brown eyes have the most. .…

    Why Is Cones Important To Humans

    In the eyes of both humans and dogs, there are two main types of light-sensitive cells referred to as rods and cones. Cone cells enable you to see color. Rods work with black and white vision, so they’re better at identifying shades in dim light. Dogs are dichromats, which means they possess only two types of cones. This enables their brains to distinguish blue from yellow, but not red from green. Humans, on the other hand, are trichromatic. Our eyes contain three types of light-sensitive cones. When cones are provoked by light, our brains identify red wavelengths from green and blue wavelengths from yellow. Dogs have fewer cone cells than humans do, but humans have fewer rod cells than dogs. This information led scientists to assume that dogs’…
