The notion of Natural Selection defined by Darwin, is basically the Survival of Fittest--“the preservation of favourable individual differences and variations, and the destruction of those which are injurious.” [Darwin, natural selection] Through this process, if the time is infinitely long, the nature can always choose the most suitable to survive, eliminate the ones who do not adapt themselves to the environment. For instance, there is an area which is passing through a climatic change. Some of the residents there will undergo a change straight away in order to keep up with the living environment, some other species who cannot will likely be extinct.
The reason why taking natural selection as a reference, is because of the timeless process it has and its unique capacity comparing to that of designers. Human can produce things and select them, but what they can refer to is only their external and visible features. In comparison, nature doesn’t care about the appearance at all, they will be preserved as long as they are beneficial to the system. And nature can also select things by their internal features, on every narrow corner that cannot be reached by human, and on very tiny changes or slightly changing processes which are not visible to human. And nature only select the ones follow her willing, which is more objective than human selection.

The key thing here is time, for the reason nature never lacks of time, so she can squander her prototyping arbitrarily and give up the poor inhabitants. But from designers’ perspective, we cannot, can we operate on time scale either. Fortunately computational technology can help us to narrow the weakness “by compressing the time and space to perform virtual prototyping and evaluation before committing ourselves to actual prototypes”.

The main aspects of Darwin’s Natural selection is about living organisms with suitable and inheritable traits for the survival and reproduction of new species. Offsprings that inherit better traits have an improve the population. For example; a giraffe will a long neck because it eats from tall trees. It is because of the tall trees( environment) that the Giraffe eventually evolves long neck as a mechanism for survival. By leaving an impact on their physical and social environment, organisms may affect the evolution of their own descendants, quite apart from changing the conditions for themselves.
Since the evolution of a species and its adaptive behaviors takes many generations for significant change to occur, there is the risk that a species’ environment will change rapidly as is the case with a natural disaster. When the environment is altered in a drastic way very quickly, there is no time for the species to adapt and, thus, may go into extinction. These abrupt changes may not allow for the time needed in order for natural selection to
Jean-Baptiste Lamarck Darwin was not the only scientist to have developed a theory of evolution; French scientist Jean-Baptiste Lamarck developed an alternative theory at the beginning of the 19th century. He is known for making a large advance in the process of finding the “right” theory of evolution; Lamarck proposed a mechanism that says that there might be a gradual change of species taking place. He is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin 's first book dealing with natural selection was published in 1859). If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. Lamarck believed that changes happened because of
1. The theory of evolution by natural selection is a mechanism used to detail how species evolve throughout time. It is not concerned with how the earth was formed, or how living things began, but how the characteristics of these living things advance from generation to generation. Charles Darwin is considered to be the father of evolution by natural selection. Darwin observed nature for many years of his life and published his findings in 1859 in a book named On the Origin of Species.
All of these changes have required animals to adapt and change at a rather fast pace. The organisms that couldn’t adapt to this change die off and the stronger organisms breed to make the species stronger and create a new trait. Examples of these changes would be species migrating, reproducing more or developing faster. Some physical changes include longer necks wider wingspan thicker or thinner fur depending on the climate in the
Charles Darwin became famous for his theory of natural selection. This theory suggests that a change in heritability traits takes place in a population over time. This is due to random mutations that occur in the genome of an individual organism, and offspring can inherit these mutations. This was defined as the key to evolution, this is because random mutations arise in the genome of an individual. Until the 19th century, the prevailing view in western societies was that differences between individuals of species were uninteresting departures from their platonic ideals of created kinds.
Gene flow has become much more common in humans in the past few centuries due advances in transportation which can bridge the gap between two populations. However, for primitive species, gene flow is not as common because species can be easily separated by things such as bodies of water and mountain ranges. Natural selection is the ability of a species to adapt to its environment in an attempt to increase its fitness. Fitness, in relation to evolution, is the ability of a species to survive and reproduce. Natural selection is the selection of species that have the highest fitness.
Monday: Charles Darwin was a biologist who studied evolution and is known for the theory of natural selection. Natural selection is the theory that organisms who are better adapted to their environment are more likely to survive and produce more offspring than organisms who aren’t adapted to their environment. Natural selection is also known as “survival of the fittest”, which further demonstrates the point that adapted organisms who are more “fit” will survive. Tuesday: Adapting to the environment is essential for many organisms survival.
Charles Darwin, associated with Cambridge University, revolutionized science with his theories of evolution. His ideas birthed new ways of understanding how species came to be. According to Darwin, the key driving force behind evolution is natural selection, which occurs under environmental pressures leading to speciation. Natural selection allows a population to adapt to changes in environmental conditions. Natural selection also explains how one species may evolve into another through the process of speciation.
The theory suggests that organisms adapted to the environment tend to survive and produce more offspring, while the others go extinct. Some people debate the relevancy and accuracy of the theory
Darwin’s evolutionary theory provided the frame for psychologist’s understanding of human behaviour and influenced the development of psychology. He proposed that animals adapt and evolve through a mechanism called natural selection and sexual selection. His book On the Origin of Species was where he noted this theory and is described as the most defining and important book in evolutionary biology. Although it is argued by some that Darwin did not discover evolution, as evolutionary ideas had already been put forward and debated, his theory proposed the means which brought about evolutionary change.
Charles Darwin was the first person to come up with and expound on the concept of natural selection. Natural Selection is the process where organisms better adapted to their environment tend to survive and produce more offspring. This concept was adopted by many scientists and is now believed to be the main process of evolution. Basically, in natural selection the variations in a species genotype increase a specific organisms chances of living and ability to procreate and increases from generation to generation, while less advantageous species eventually go extinct. There are many factors that could lead to natural selection including, differences in survival, in fertility, in rate of development, success of mating, and etc.
An example of natural selection happening is a type of shark. “Sharks are colored white on the underside and blue or gray on the top. This is their camouflage as the top blends with the watercolor to someone looking down into the water and the bottom blends with the light coming through the water from above. ”(3). This shows that natural selection if fact is a process that everyone can agree on, as there is enough prove and evidence and it can be tested with similar results.
Charles Darwin is famous for his studies of mechanisms that bring about evolutionary change and for formulating the theory of natural selection which is defined by Scupin and DeCorse (2010) as ‘genetic change in a population resulting from differential reproductive success.’ The purpose of this essay is to discuss the importance of Darwin’s theory. During Darwin’s time contemporaries responded to his theory because it brought new drastic changes to thoughts regarding evolution. He did not convince many of the other theorists of his time and only a handful of scientists first accepted what his theory stated.
Charles Darwin was born to Waring Darwin and Susannah Wedgwood on February 12, 1809 in Shrewsbury, England. Charles was born into a wealthy family; he was the second youngest child born. Darwin was related to two scientists. His father was a medical doctor, and his grandfather, Erasmus Darwin was a well known botanist. His father and grand father probably helped to nurture his love for science.
