What is Free Evolution?
Free evolution is the concept that natural processes can cause organisms to evolve over time. This includes the appearance and development of new species.
This has been demonstrated by numerous examples, including stickleback fish varieties that can be found in fresh or saltwater and walking stick insect types that are apprehensive about particular host plants. These reversible traits, however, cannot explain fundamental changes in basic body plans.
Evolution through Natural Selection
Scientists have been fascinated by the evolution of all the living creatures that inhabit our planet for centuries. The most widely accepted explanation is Charles Darwin's natural selection, an evolutionary process that is triggered when more well-adapted individuals live longer and reproduce more successfully than those who are less well-adapted. As time passes, the number of well-adapted individuals grows and eventually creates an entirely new species.
Natural selection is a cyclical process that involves the interaction of three factors: variation, inheritance and reproduction. Variation is caused by mutation and sexual reproduction both of which enhance the genetic diversity within an animal species. Inheritance refers the transmission of a person’s genetic traits, which include both dominant and recessive genes to their offspring. Reproduction is the process of producing fertile, viable offspring. This can be done by both asexual or sexual methods.
Natural selection is only possible when all the factors are in harmony. For instance the case where the dominant allele of a gene allows an organism to live and reproduce more often than the recessive allele the dominant allele will be more prominent within the population. If the allele confers a negative advantage to survival or reduces the fertility of the population, it will disappear. The process is self reinforcing which means that an organism with an adaptive characteristic will live and 에볼루션코리아 reproduce more quickly than those with a maladaptive feature. The greater an organism's fitness as measured by its capacity to reproduce and survive, is the greater number of offspring it produces. Individuals with favorable traits, like a long neck in Giraffes, or the bright white color patterns on male peacocks, are more likely than others to survive and reproduce, which will eventually lead to them becoming the majority.
Natural selection is only an aspect of populations and not on individuals. This is a significant distinction from the Lamarckian evolution theory that states that animals acquire traits through usage or inaction. For example, if a giraffe's neck gets longer through stretching to reach prey and its offspring will inherit a longer neck. The difference in neck length between generations will continue until the giraffe's neck becomes too long to no longer breed with other giraffes.
Evolution by Genetic Drift
Genetic drift occurs when alleles of the same gene are randomly distributed within a population. In the end, 에볼루션코리아 one will reach fixation (become so widespread that it is unable to be removed by natural selection) and other alleles will fall to lower frequencies. In the extreme it can lead to a single allele dominance. The other alleles are virtually eliminated and 에볼루션코리아 heterozygosity been reduced to a minimum. In a small number of people it could lead to the complete elimination of recessive alleles. Such a scenario would be known as a bottleneck effect and it is typical of the kind of evolutionary process that takes place when a lot of individuals migrate to form a new group.
A phenotypic bottleneck may occur when the survivors of a catastrophe such as an epidemic or a mass hunting event, are condensed within a narrow area. The survivors will share an allele that is dominant and will have the same phenotype. This could be caused by earthquakes, war, or even plagues. Regardless of the cause, the genetically distinct population that remains is susceptible to genetic drift.
Walsh Lewens, Lewens, and Ariew use Lewens, Walsh and Ariew employ a "purely outcome-oriented" definition of drift as any deviation from expected values for different fitness levels. They provide a well-known example of twins that are genetically identical, have the exact same phenotype but one is struck by lightening and dies while the other lives and reproduces.
This type of drift is vital to the evolution of an entire species. This isn't the only method of evolution. The main alternative is a process called natural selection, in which the phenotypic variation of the population is maintained through mutation and migration.
Stephens claims that there is a vast difference between treating the phenomenon of drift as a force or cause, and treating other causes such as selection mutation and migration as causes and forces. He argues that a causal process explanation of drift permits us to differentiate it from these other forces, and this distinction is crucial. He also argues that drift has a direction, that is, it tends to eliminate heterozygosity. He also claims that it also has a magnitude, that is determined by the size of the population.
Evolution by Lamarckism
In high school, students study biology they are often introduced to the work of Jean-Baptiste Lamarck (1744 - 1829). His theory of evolution is generally known as "Lamarckism" and it states that simple organisms grow into more complex organisms via the inheritance of traits that result from an organism's natural activities use and misuse. Lamarckism is typically illustrated by a picture of a giraffe extending its neck further to reach higher up in the trees. This causes the necks of giraffes that are longer to be passed onto their offspring who would grow taller.
Lamarck was a French zoologist and, in his inaugural lecture for his course on invertebrate Zoology at the Museum of Natural History in Paris on the 17th of May in 1802, he presented an innovative concept that completely challenged the previous understanding of organic transformation. According to Lamarck, living things evolved from inanimate material 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 having given the subject his first comprehensive and comprehensive treatment.
The most popular story is that Lamarckism was an opponent to Charles Darwin's theory of evolution through natural selection, and that the two theories fought each other in the 19th century. Darwinism eventually won, leading to the development of what biologists call the Modern Synthesis. The Modern Synthesis theory denies the possibility that acquired traits 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 the next generation. However, this notion was never a major part of any of their evolutionary theories. This is partly due to the fact that it was never validated scientifically.
However, it has been more than 200 years since Lamarck was born and, in the age of genomics there is a huge body of evidence supporting the heritability of acquired traits. This is often called "neo-Lamarckism" or more frequently, epigenetic inheritance. It is a variant of evolution that is as relevant as the more popular neo-Darwinian model.
Evolution by adaptation
One of the most common misconceptions about evolution is being driven by a struggle to survive. This is a false assumption and 에볼루션 코리아 ignores other forces driving evolution. The fight for survival can be more accurately described as a struggle to survive within a specific environment, which may involve not only other organisms, but also the physical environment.
Understanding how adaptation works is essential to comprehend evolution. Adaptation refers to any particular characteristic that allows an organism to survive and reproduce within its environment. It can be a physiological structure, such as fur or feathers, or a behavioral trait like moving into the shade in hot weather or stepping out at night to avoid the cold.
The survival of an organism depends on its ability to extract energy from the environment and to interact with other living organisms and their physical surroundings. The organism must have the right genes for producing offspring, and be able to find enough food and resources. Moreover, the organism must be able to reproduce itself at a high rate within its niche.
These elements, along with mutations and gene flow can result in an alteration in the ratio of different alleles within a population’s gene pool. The change in frequency of alleles could lead to the development of new traits and eventually new species over time.
A lot of the traits we find appealing in plants and animals are adaptations. For instance the lungs or gills which draw oxygen from air feathers and fur for insulation long legs to run away from predators, and camouflage to hide. To comprehend adaptation it is essential to differentiate between physiological and behavioral traits.
Physiological adaptations, such as thick fur or gills are physical traits, while behavioral adaptations, like the tendency to seek out companions or 무료 에볼루션 to retreat to shade in hot weather, are not. Additionally, it is important to remember that lack of planning is not a reason to make something an adaptation. A failure to consider the consequences of a decision, even if it appears to be rational, may make it unadaptive.
