What is Free Evolution?
Free evolution is the idea that natural processes can lead to the development of organisms over time. This includes the appearance and growth of new species.
Many examples have been given of this, including various kinds of stickleback fish that can live in salt or 에볼루션 무료 바카라 fresh water, as well as walking stick insect varieties that are attracted to particular host plants. These mostly reversible traits permutations do not explain the fundamental changes in basic body plans.
Evolution through Natural Selection
The evolution of the myriad living organisms on Earth is an enigma that has intrigued scientists for centuries. Charles Darwin's natural selection theory is the most well-known explanation. This happens when people who are more well-adapted are able to reproduce faster and longer than those who are less well-adapted. Over time, the population of well-adapted individuals grows and eventually develops into a new species.
Natural selection is an ongoing process and involves the interaction of 3 factors including reproduction, variation and inheritance. Variation is caused by mutations and sexual reproduction, both of which increase the genetic diversity of the species. Inheritance is the term used to describe the transmission of a person’s genetic traits, including both dominant and 에볼루션 바카라 사이트 recessive genes, to their offspring. Reproduction is the process of producing fertile, viable offspring, which includes both asexual and sexual methods.
All of these variables must be in harmony to allow natural selection to take place. If, for instance the dominant gene allele allows an organism to reproduce and live longer than the recessive allele then the dominant allele will become more prevalent in a population. But if the allele confers a disadvantage in survival or 에볼루션 decreases fertility, it will disappear from the population. This process is self-reinforcing meaning that a species that has a beneficial trait can reproduce and survive longer than one with an inadaptive trait. The more offspring an organism produces the more fit it is which is measured by its capacity to reproduce and survive. People with good traits, like a long neck in Giraffes, or the bright white patterns on male peacocks are more likely to others to survive and reproduce and eventually lead to them becoming the majority.
Natural selection is an aspect of populations and not on individuals. This is a significant distinction from the Lamarckian theory of evolution that states that animals acquire traits either through use or lack of use. For instance, if the Giraffe's neck grows longer due to stretching to reach for prey, its offspring will inherit a longer neck. The differences in neck size between generations will increase until the giraffe is no longer able to reproduce with other giraffes.
Evolution through Genetic Drift
In genetic drift, alleles of a gene could attain different frequencies in a population by chance events. Eventually, one of them will attain fixation (become so common that it is unable to be removed through natural selection) and other alleles will fall to lower frequencies. In the extreme, this leads to a single allele dominance. Other alleles have been virtually eliminated and heterozygosity decreased to zero. In a small number of people it could lead to the complete elimination of recessive alleles. This is known as the bottleneck effect. It is typical of the evolution process that occurs when a large number individuals migrate to form a group.
A phenotypic bottleneck can also occur when the survivors of a disaster, such as an epidemic or a mass hunting event, are concentrated within a narrow area. The remaining individuals will be mostly homozygous for the dominant allele meaning that they all have the same phenotype and will thus have the same fitness traits. This could be caused by a war, earthquake, or even a plague. Whatever the reason the genetically distinct group that remains could be prone to genetic drift.
Walsh Lewens, Walsh, and Ariew define drift as a departure from expected values due to differences in fitness. They give the famous example of twins who are both genetically identical and have exactly the same phenotype. However, one is struck by lightning and dies, but the other lives to reproduce.
This type of drift is vital to the evolution of the species. However, it is not the only way to progress. The primary alternative is to use a process known as natural selection, where the phenotypic diversity of the population is maintained through mutation and migration.
Stephens claims that there is a significant distinction between treating drift as a force or a cause and treating other causes of evolution like mutation, selection and migration as forces or causes. He argues that a causal process account of drift permits us to differentiate it from the other forces, and that this distinction is vital. He also argues that drift is a directional force: that is, it tends to eliminate heterozygosity. He also claims that it also has a magnitude, that is determined by the size of population.
Evolution through 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 is often known as "Lamarckism" and it asserts that simple organisms evolve into more complex organisms by the inheritance of traits which result from the organism's natural actions use and misuse. Lamarckism can be demonstrated by an giraffe's neck stretching to reach higher branches in the trees. This would cause giraffes' longer necks to be passed to their offspring, 에볼루션 코리아 who would then become taller.
Lamarck was a French zoologist and, in his lecture to begin his course on invertebrate Zoology at the Museum of Natural History in Paris on 17 May 1802, he introduced a groundbreaking concept that radically challenged previous thinking about organic transformation. According to Lamarck, living creatures evolved from inanimate matter through a series gradual steps. Lamarck was not the only one to suggest that this could be the case but the general consensus is that he was the one being the one who gave the subject his first comprehensive and comprehensive treatment.
The most popular story is that Charles Darwin's theory of natural selection and Lamarckism were competing in the 19th century. Darwinism eventually won and led to the creation of what biologists refer to as the Modern Synthesis. The theory argues that traits acquired through evolution can be acquired through inheritance and instead argues that organisms evolve through the action of environmental factors, like natural selection.
Lamarck and his contemporaries believed in the idea that acquired characters could be passed on to future generations. However, this idea was never a major part of any of their evolutionary theories. This is due to the fact that it was never scientifically validated.
But it is now more than 200 years since Lamarck was born and, in the age of genomics there is a vast amount of evidence to support the possibility of inheritance of acquired traits. This is also known as "neo Lamarckism", or more commonly epigenetic inheritance. It is a form of evolution that is just as relevant as the more popular Neo-Darwinian theory.
Evolution through the process of adaptation
One of the most popular misconceptions about evolution is that it is a result of a kind of struggle for survival. This is a false assumption and 에볼루션 바카라 사이트 overlooks other forces that drive evolution. The fight for survival can be more accurately described as a struggle to survive within a particular environment, which can involve not only other organisms, but also the physical environment itself.
Understanding how adaptation works is essential to understand evolution. It is a feature that allows living organisms to survive in its environment and reproduce. It can be a physiological structure, such as fur or feathers, or a behavioral trait like moving to the shade during the heat or leaving at night to avoid the cold.
The capacity of a living thing to extract energy from its surroundings and interact with other organisms as well as their physical environment, is crucial to its survival. The organism must have the right genes to create offspring and to be able to access sufficient food and resources. Moreover, the organism must be capable of reproducing at an optimal rate within its niche.
These elements, in conjunction with gene flow and 에볼루션 바카라 사이트 mutation can result in a change in the proportion of alleles (different forms of a gene) in the gene pool of a population. The change in frequency of alleles could lead to the development of new traits, and eventually new species in the course of time.
Many of the characteristics we appreciate in plants and animals are adaptations. For instance, lungs or gills that extract oxygen from air feathers and fur for insulation long legs to run away from predators, and camouflage to hide. To understand 에볼루션 바카라 무료 the concept of adaptation, it is important to differentiate between physiological and behavioral characteristics.
Physiological adaptations like thick fur or gills, are physical traits, whereas behavioral adaptations, like the desire to find companions or to move into the shade in hot weather, are not. In addition it is important to note that lack of planning does not mean that something is an adaptation. A failure to consider the effects of a behavior, even if it appears to be rational, could make it inflexible.
