How Does Natural Selection Affect The Human Body?

The fifth part of the evolution theory is natural selection. Natural selection is an idea that life doesn’t require creation or guidance from a supernatural being. Natural selection depends only on nature in which the population will adapt to their environment while the one who are unable to adapt will die off. But natural selection cannot provide perfection but can only help the creatures to evolve just enough to be able to survive.

Animals fight for survival daily, and sometimes their lives depend on their ability to adapt with their surrounding environments. Natural Selection is the process in which individuals have certain traits that allow

Research speculates that the modern humans and Neanderthals coexisted in Europe for around 5,000 years. To put that into perspective, 5,000 years is around 250 generations in “human-time.” Sharing about 99.5% DNA with the Neanderthals, the largest bone in the foot may be one of the biggest differences that set the modern humans apart to out-live the Neanderthals. Both Neanderthals and modern humans have arched feet, but the height of heal differs. Dr David Raichlen found that because the heal of the Neanderthal was taller, it proved less spring during running and also stabilized the ankle. This made the Neanderthals known for walking, and to which why the lower heal increased the ability for modern humans to out run its closest cousin.

Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

The goal of natural selection is to promote healthy genes that enable us to survive. Natural selection weeds out harmful genes that make us weak.

Many people are familiar with the words natural selection, an idea that was popularized by Darwin in the 19th century; to simply define it, natural selection is nature’s editing mechanism that results in the favoring of some individuals over others when exposed to certain environmental factors. Artificial selection parallels the process of natural selection but with an added twist: the involvement of human beings. Artificial selection is “a process in which humans consciously select for or against particular features in organisms” allowing “only organisms with the desired feature to reproduce or may provide more resources to the organisms with the desired feature” (Artificial Selection, n.d.).

In the process of natural selection, individuals that have certain inherited traits tend to survive and

One thing about natural selection that many people do not understand that natural selection does not increase the odds of survival for a species, but for individuals in that species. This makes sense when someone considers humans. Humans live in many social cultures, where for instance, the odds of survival in a group can be improved by the selection of certain traits that does not improve an individual’s odds of survival. Coyne states, one never sees the type of adaptations that benefit the group to the detriment of an individual (p.122).

Natural selection involves the adaptation of a species to better survive in their designated environment. When organisms reproduce, they pass down their DNA to their offspring. For example, a child that is tall is the result of their parent being tall as well. Parents pass down traits to their children. When it comes to survival, some organisms are better at it than others based on the traits that they have acquired. Some organisms can camouflage from predators while members of the same species do not obtain that same trait. With that in mind, the ones that can camouflage will most likely survive in certain environments and they will then pass on that trait when they reproduce. Since these traits are advantageous, they are passed on to more and more offspring through time and it will eventually overcome any original traits that species first started out with. It’s kind of like the current state of sexual misconduct in Hollywood. We have our directors, actors, agents, and so forth. However, as time goes on, some do not survive in the business based on their inherently evil traits and they get weeded out just like some species in the wild. As generations pass, these organisms have then adapted to fit the environment and better survive based on their inherited traits.

Natural selection is a scientific phrase students like me have learned lots about. according to my prior knowledge and Rifkin “If you believe in evolution by natural

Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.

Conclusion: In conclusion the pelvis of the early hominin of the homo genus would have had wider pelvis’s, shorter legs, smaller iliac plates and non-curved hip bones meaning a lack in locomotion efficiency causes more energy loss when they walk because there is more hip movement to support the unsupported side of the leg, through evolutionary processes such as thermoregulation hominins body started to adapt to the heat of the sun and their pelvis started to grow more narrow with a smaller birth canal furthermore having longer leg ligaments and gluteals, this would help with locomotion efficiency as the hip bone is more curved and acts as a stabiliser for better balance whilst walking causing less energy loss because less hip movement whilst

So, these traits can be transferred when producing offspring. Here is a good example of what it is Natural Selection, the polar bear. The polar bear’s fur is the color white which helps them to camouflage in the snow. In addition, the polar bear’s white fur can insulate against the cold weather and that is a major advantage for them to survive in the arctic regions of the earth. In the other hand, the polar bears are different from the brown bear that need to be in the warm weather to be able to survive. Even more, another good reason that proved that the polar bears take a big advantage of the natural selection is that they have a big amount of fat that they store in their body and that makes them able to spend months without

My book discusses quite a lot about natural selection and this is a topic directly related to biology. Natural selection has everything to do with evolution and this is a part of the study of biology. Natural selection creates new species and somehow from this process humans came to be as well as every other living organism. This is a slow process that takes generations to modify genes enough to form an entirely new species, but it is done. Since all new species come from old ones, every living organism is interconnected on some level. This is the belief that all organisms on earth share a common ancestor. Old species will continue forming chains of new species and the cycle continues, but not all organisms prosper. Natural selection only allows

The human foot is an example of micro-evolutionary and macro-evolutionary changes. It has had to adapt to bipedal walking and the stress that is caused by being upright. To identify changes in the human foot; comparative, molecular, and biocultural approaches and their paradigms are used. Therefore, different, and cumulative approaches are needed to make informed hypotheses in biological anthropology. The foot will be shown as an example of approaches commonly used and the resulting perspectives in biological anthropology.
