What is Free Evolution?<br><br>Free evolution is the notion that the natural processes of living organisms can lead to their development over time. This includes the creation of new species as well as the change in appearance of existing species.<br><br>This has been proven by numerous examples, including stickleback fish varieties that can be found in salt or fresh water, and walking stick insect species that are apprehensive about particular host plants. These typically reversible traits cannot explain fundamental changes to the body's basic plans.<br><br>Evolution by Natural Selection<br><br>The development of the myriad living creatures on Earth is a mystery that has fascinated scientists for decades. 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 effectively than those that are less well-adapted. As time passes, a group of well-adapted individuals increases and eventually becomes a new species.<br><br>Natural selection is a cyclical process that is characterized by the interaction of three factors including inheritance, variation, and reproduction. Variation is caused by mutations and sexual reproduction both of which increase the genetic diversity of an animal species. Inheritance is the term used to describe the transmission of genetic characteristics, which includes recessive and dominant genes to their offspring. Reproduction is the process of producing fertile, viable offspring. This can be accomplished via sexual or asexual methods.<br><br>Natural selection can only occur when all of these factors are in equilibrium. If, for instance, a dominant gene allele makes an organism reproduce and survive more than the recessive allele The dominant allele becomes more prevalent in a group. However, if the gene confers a disadvantage in survival or reduces fertility, it will be eliminated from the population. This process is self-reinforcing meaning that a species with a beneficial characteristic can reproduce and survive longer than one with a maladaptive characteristic. The greater an organism's fitness, measured by its ability reproduce and survive, is the greater number of offspring it produces. People with good traits, like a longer neck in giraffes, or bright white colors in male peacocks are more likely to survive and [http://wx.abcvote.cn/home.php?mod=space&uid=4127169 ์๋ณผ๋ฃจ์ ๋ฐ์นด๋ผ ๋ฌด๋ฃ] produce offspring, and thus will become the majority of the population over time.<br><br>Natural selection is only a force for populations, not individual organisms. This is a significant distinction from the Lamarckian evolution theory that states that animals acquire traits due to use or lack of use. For instance, if the giraffe's neck gets longer through reaching out to catch prey, its offspring will inherit a more long neck. The difference in neck size between generations will increase until the giraffe becomes unable to reproduce with other giraffes.<br><br>Evolution through Genetic Drift<br><br>In genetic drift, the alleles at a gene may attain different frequencies within a population by chance events. In the end, only one will be fixed (become common enough to no longer be eliminated by natural selection) and the other alleles will diminish in frequency. This can result in dominance at the extreme. The other alleles are essentially eliminated, and heterozygosity decreases to zero. In a small group it could result in the complete elimination of the recessive gene. This scenario is called the bottleneck effect. It is typical of an evolution process that occurs when the number of individuals migrate to form a group.<br><br>A phenotypic bottleneck may also occur when the survivors of a catastrophe such as an outbreak or mass hunt incident are concentrated in the same area. The survivors will carry a dominant allele and thus will have the same phenotype. This situation could be caused by war, [http://bbs.pc590.com/home.php?mod=space&uid=151514 ์๋ณผ๋ฃจ์ ๊ฒ์ด๋ฐ] earthquakes, or even plagues. Whatever the reason, the genetically distinct population that is left might be prone to genetic drift.<br><br>Walsh, Lewens and Ariew define drift as a deviation from expected values due to differences in fitness. They cite the famous example of twins who are both genetically identical and share the same phenotype. However one is struck by lightning and dies, while the other is able to reproduce.<br><br>This kind of drift could be vital to the evolution of an entire species. However, it's not the only method to evolve. The primary alternative is to use a process known as natural selection, in which the phenotypic variation of a population is maintained by mutation and migration.<br><br>Stephens asserts that there is a major difference between treating the phenomenon of drift as a force or an underlying cause, and treating other causes of evolution such as selection, mutation and migration as forces or causes. Stephens claims that a causal process explanation of drift allows us to distinguish it from these other forces, and that this distinction is essential. He further argues that drift is a directional force: that is it tends to reduce heterozygosity, and that it also has a size, which is determined by population size.<br><br>Evolution through Lamarckism<br><br>When high school students study biology, they are often introduced to the work of Jean-Baptiste Lamarck (1744 - 1829). His theory of evolution, also referred to as "Lamarckism", states that simple organisms transform into more complex organisms taking on traits that result from an organism's use and disuse. Lamarckism can be demonstrated by an giraffe's neck stretching to reach higher leaves in the trees. This process would cause giraffes to give their longer necks to offspring, who would then become taller.<br><br>Lamarck the French Zoologist from France, presented an innovative idea in his opening lecture at the Museum of Natural History of Paris. He challenged previous thinking on organic transformation. According Lamarck, living organisms evolved from inanimate matter by a series of gradual steps. Lamarck was not the only one to suggest that this could be the case, but his reputation is widely regarded as being the one who gave the subject its first general and [http://www.swanmei.com/space-uid-3294438.html ์๋ณผ๋ฃจ์ ๊ฒ์ด๋ฐ] comprehensive treatment.<br><br>The most popular story is that Charles Darwin's theory on natural selection and Lamarckism fought in the 19th century. Darwinism ultimately won and led to what biologists call the Modern Synthesis. The Modern Synthesis theory denies that acquired characteristics can be inherited, and instead suggests that organisms evolve by the symbiosis of environmental factors, like natural selection.<br><br>Lamarck and his contemporaries supported the idea that acquired characters could be passed on to the next generation. However, this idea was never a central part of any of their evolutionary theories. This is due to the fact that it was never scientifically tested.<br><br>But it is now more than 200 years since Lamarck was born and in the age genomics, there is a large body of evidence supporting the heritability of acquired characteristics. This is sometimes referred to as "neo-Lamarckism" or, more commonly, epigenetic inheritance. It is a variant of evolution that is just as relevant as the more popular Neo-Darwinian theory.<br><br>Evolution by Adaptation<br><br>One of the most popular misconceptions about evolution is being driven by a fight for survival. This view is inaccurate and overlooks other forces that drive evolution. The struggle for survival is more accurately described as a struggle to survive in a specific environment, which can be a struggle that involves not only other organisms, but also the physical environment.<br><br>Understanding how adaptation works is essential to understand evolution. It refers to a specific characteristic that allows an organism to survive and reproduce within its environment. It can be a physical structure, such as feathers or fur. Or it can be a characteristic of behavior such as moving into the shade during the heat, or coming out to avoid the cold at night.<br><br>The ability of an organism to draw energy from its surroundings and interact with other organisms, as well as their physical environments, is crucial to its survival. The organism must have the right genes for producing offspring and be able find enough food and resources. Furthermore, the organism needs to be capable of reproducing at a high rate within its environment.<br><br>These factors, together with mutation and gene flow result in a change in the proportion of alleles (different varieties of a particular gene) in a population's gene pool. Over time, this change in allele frequencies can result in the development of new traits and eventually new species.<br><br>A lot of the traits we find appealing in animals and plants are adaptations. For example the lungs or gills which extract oxygen from the air feathers and fur for insulation, long legs to run away from predators and camouflage for hiding. To understand the concept of adaptation, it is important to distinguish between behavioral and physiological characteristics.<br><br>Physiological traits like thick fur and [http://douerdun.com/home.php?mod=space&uid=1780852 ์๋ณผ๋ฃจ์ ์ฌ์ดํธ] ๋ธ๋์ญ; [https://cameradb.review/wiki/The_Reasons_Free_Evolution_Is_Everyones_Desire_In_2024 linked site], gills are physical traits. The behavioral adaptations aren't, such as the tendency of animals to seek companionship or move into the shade in hot temperatures. Additionally, it is important to remember that lack of planning does not make something an adaptation. In fact, a failure to think about the implications of a behavior can make it ineffective despite the fact that it might appear logical or even necessary.
