What is Free Evolution?

Free evolution is the notion that natural processes can cause organisms to evolve over time. This includes the emergence and development of new species.

8018766-1-890x664.jpgThis has been demonstrated by numerous examples of stickleback fish species that can thrive in salt or fresh water, and walking stick insect types that are apprehensive about specific host plants. These mostly reversible trait permutations however, 에볼루션 바카라사이트 are not able to explain fundamental changes in basic body plans.

Evolution by Natural Selection

The evolution of the myriad living creatures on Earth is an enigma that has intrigued scientists for decades. The most well-known explanation is Darwin's natural selection process, an evolutionary process that occurs when individuals that are better adapted survive and reproduce more successfully than those that are less well adapted. Over time, the population of well-adapted individuals grows and eventually creates a new species.

Natural selection is an ongoing process that is characterized by the interaction of three factors that are inheritance, variation and reproduction. Mutation and 에볼루션바카라사이트 sexual reproduction increase the genetic diversity of a species. Inheritance is the passing of a person's genetic traits to their offspring which includes both dominant and recessive alleles. Reproduction is the generation of fertile, viable offspring which includes both asexual and sexual methods.

Natural selection is only possible when all the factors are in harmony. If, for 에볼루션 바카라 무료체험 instance, a dominant gene allele causes an organism reproduce and 에볼루션 바카라사이트 last longer than the recessive gene, then the dominant allele becomes more prevalent in a population. If the allele confers a negative survival advantage or lowers the fertility of the population, it will be eliminated. The process is self-reinforcing, meaning that an organism that has a beneficial trait is more likely to survive and reproduce than one with an inadaptive characteristic. The more fit an organism is, measured by its ability reproduce and endure, 에볼루션 코리아 is the higher number of offspring it produces. People with good characteristics, such as the long neck of Giraffes, or the bright white patterns on male peacocks are more likely than others to live and reproduce and eventually lead to them becoming the majority.

Natural selection only affects populations, 에볼루션카지노 not individual organisms. This is a significant distinction from the Lamarckian theory of evolution, which states that animals acquire characteristics through use or neglect. If a giraffe extends its neck in order to catch prey and the neck grows larger, then its offspring will inherit this characteristic. The difference in neck size between generations will increase until the giraffe is no longer able to breed with other giraffes.

Evolution through Genetic Drift

In genetic drift, alleles of a gene could be at different frequencies within a population through random events. At some point, one will attain fixation (become so widespread that it cannot be removed by natural selection) and other alleles will fall to lower frequency. In extreme cases this, it leads to a single allele dominance. The other alleles are essentially eliminated, and heterozygosity is reduced to zero. In a small group, this could lead to the complete elimination of recessive alleles. This is known as the bottleneck effect. It is typical of the evolutionary process that occurs whenever a large number individuals migrate to form a population.

A phenotypic bottleneck can also occur when the survivors of a catastrophe like an epidemic or mass hunting event, 에볼루션바카라 are condensed within a narrow area. The survivors will have a dominant allele and thus will share the same phenotype. This could be the result of a war, an earthquake or even a disease. Whatever the reason the genetically distinct population that is left might be prone to genetic drift.

Walsh, Lewens, and Ariew use a "purely outcome-oriented" definition of drift as any departure from the expected values for variations in fitness. They cite the famous example of twins who are genetically identical and have exactly the same phenotype. However, one is struck by lightning and dies, but the other continues to reproduce.

This kind of drift could play a crucial part in the evolution of an organism. However, it is not the only way to evolve. The primary alternative is a process known as natural selection, in which the phenotypic diversity of a population is maintained by mutation and migration.

Stephens argues that there is a significant distinction between treating drift as a force or as an underlying cause, and considering other causes of evolution like selection, mutation, and migration as forces or causes. Stephens claims that a causal process account of drift allows us separate it from other forces and that this differentiation is crucial. He further argues that drift is both direction, 에볼루션 바카라사이트 i.e., it tends to eliminate heterozygosity. It also has a size, that is determined by population size.

Evolution by Lamarckism

When students in high school study biology, they are often introduced to the work of Jean-Baptiste Lamarck (1744 - 1829). His theory of evolution, commonly called "Lamarckism is based on the idea that simple organisms develop into more complex organisms by inheriting characteristics that result from the organism's use and misuse. Lamarckism is typically illustrated by an image of a giraffe extending its neck further to reach the higher branches in the trees. This would cause the longer necks of giraffes to be passed to their offspring, who would then become taller.

Lamarck, a French Zoologist, introduced an idea that was revolutionary in his 17 May 1802 opening lecture at the Museum of Natural History of Paris. He challenged the traditional thinking about organic transformation. In his view living things evolved from inanimate matter through a series of gradual steps. Lamarck was not the only one to suggest that this might be the case but he is widely seen as being the one who gave the subject its first broad and comprehensive analysis.

The predominant story is that Charles Darwin's theory on natural selection and Lamarckism were competing in the 19th century. Darwinism eventually won, leading to the development of what biologists now call the Modern Synthesis. The theory argues that acquired characteristics can be acquired through inheritance and instead suggests that organisms evolve through the action of environmental factors, including natural selection.

Lamarck and his contemporaries supported the idea that acquired characters could be passed down to future generations. However, this concept was never a major part of any of their evolutionary theories. This is partly because it was never scientifically tested.

It's been more than 200 years since Lamarck was born and in the age genomics there is a vast amount of evidence that supports the heritability of acquired characteristics. This is referred to as "neo Lamarckism", or more commonly epigenetic inheritance. It is a form of evolution that is just as valid as the more popular Neo-Darwinian theory.

Evolution through Adaptation

One of the most popular misconceptions about evolution is that it is a result of a kind of struggle to survive. This notion is not true and ignores other forces driving evolution. The struggle for existence is better described as a struggle to survive in a particular environment. This could include not only other organisms as well as the physical environment.

Understanding how adaptation works is essential to understand evolution. It is a feature that allows a living thing to live in its environment and reproduce. It can be a physiological feature, such as fur or feathers or a behavior, such as moving to the shade during the heat or leaving at night to avoid the cold.

The survival of an organism is dependent on its ability to extract energy from the environment and interact with other organisms and their physical environments. The organism must possess the right genes to produce offspring and be able find sufficient food and resources. The organism should also be able reproduce itself at the rate that is suitable for its niche.

These factors, along with gene flow and mutation, lead to an alteration in the percentage of alleles (different varieties of a particular gene) in the gene pool of a population. As time passes, this shift in allele frequencies could result in the emergence of new traits and ultimately new species.

A lot of the traits we admire about animals and plants are adaptations, for example, the lungs or gills that extract oxygen from the air, fur or feathers to protect themselves, long legs for running away from predators and camouflage for hiding. However, a thorough understanding of adaptation requires attention to the distinction between the physiological and behavioral characteristics.

Depositphotos_371309416_XL-890x664.jpgPhysical characteristics like thick fur and gills are physical traits. Behavioral adaptations are not like the tendency of animals to seek out companionship or retreat into shade in hot weather. In addition it is important to remember that lack of planning does not make something an adaptation. In fact, failure to consider the consequences of a behavior can make it unadaptive even though it may appear to be logical or even necessary.
