What is Free Evolution?
Free evolution is the concept that natural processes can cause organisms to evolve over time. This includes the evolution of new species as well as the change in appearance of existing species.
This has been demonstrated by numerous examples, including stickleback fish varieties that can live in fresh or saltwater and walking stick insect types that are apprehensive about particular host plants. These typically reversible traits do not explain the fundamental changes in the basic body plan.
Evolution through Natural Selection
The evolution of the myriad living organisms on Earth is an enigma that has intrigued scientists for decades. The most well-known explanation is that of Charles Darwin's natural selection process, an evolutionary process that is triggered when more well-adapted individuals live longer and reproduce more effectively than those that are less well-adapted. Over time, a population of well-adapted individuals expands and eventually forms a whole new species.
Natural selection is an ongoing process and involves the interaction of 3 factors: variation, reproduction and inheritance. Sexual reproduction and mutations increase the genetic diversity of an animal species. Inheritance is the passing of a person's genetic traits to the offspring of that person, which includes both recessive and dominant alleles. Reproduction is the process of producing fertile, viable offspring. This can be accomplished by both asexual or sexual methods.
Natural selection can only occur when all these elements are in equilibrium. For instance when a dominant allele at the gene can cause an organism to live and 에볼루션 reproduce more frequently than the recessive allele, the dominant allele will become more prominent within the population. If the allele confers a negative advantage to survival or decreases the fertility of the population, it will go away. The process is self-reinforcing, which means that an organism with an adaptive trait will survive and reproduce more quickly than those with a maladaptive trait. The more offspring an organism can produce the better its fitness, which is measured by its capacity to reproduce and survive. Individuals with favorable characteristics, such as having a long neck in Giraffes, 에볼루션 바카라 or the bright white patterns on male peacocks, are more likely than others to live and reproduce which eventually leads to them becoming the majority.
Natural selection is only a force for populations, not individuals. This is an important distinction from the Lamarckian theory of evolution which claims that animals acquire characteristics by use or 에볼루션 코리아 inactivity. If a giraffe stretches its neck to catch prey, 에볼루션 사이트 and 에볼루션 블랙잭 the neck becomes longer, then the children will inherit this characteristic. The difference in neck length between generations will continue until the giraffe's neck becomes so long that it can no longer breed with other giraffes.
Evolution by Genetic Drift
In genetic drift, the alleles of a gene could reach different frequencies in a group through random events. In the end, one will reach fixation (become so widespread that it is unable to be removed through natural selection), while the other alleles drop to lower frequencies. This can lead to an allele that is dominant at the extreme. The other alleles are basically eliminated and heterozygosity has decreased to a minimum. In a small group this could lead to the complete elimination the recessive gene. This is known as a bottleneck effect and it is typical of the kind of evolutionary process when a large number of individuals migrate to form a new population.
A phenotypic bottleneck could occur when survivors of a catastrophe, such as an epidemic or mass hunting event, are concentrated in a limited area. The remaining individuals will be largely homozygous for the dominant allele which means they will all have the same phenotype, and 에볼루션 therefore have the same fitness characteristics. This situation might be caused by war, an earthquake or even a cholera outbreak. The genetically distinct population, if left, could be susceptible to genetic drift.
Walsh, Lewens, and Ariew utilize Lewens, Walsh and Ariew employ a "purely outcome-oriented" definition of drift as any departure from the expected values for different fitness levels. They provide the famous case of twins who are genetically identical and share the same phenotype. However, 에볼루션 (bioimagingcore.be) one is struck by lightning and dies, whereas the other lives to reproduce.
This kind of drift can play a crucial role in the evolution of an organism. However, it is not the only way to evolve. Natural selection is the most common alternative, where mutations and migration maintain the phenotypic diversity of a population.
Stephens argues that there is a major distinction between treating drift as a force or an underlying cause, and considering other causes of evolution like mutation, selection and migration as causes or causes. Stephens claims that a causal process account of drift allows us to distinguish it from the other forces, and that this distinction is crucial. He also claims that drift is a directional force: that is it tends to reduce heterozygosity. It also has a specific magnitude that is determined by population size.
Evolution by Lamarckism
In high school, students take biology classes, they are frequently introduced to the work of Jean-Baptiste Lamarck (1744 - 1829). His theory of evolution, often called "Lamarckism, states that simple organisms transform into more complex organisms taking on traits that are a product of the organism's use and misuse. Lamarckism can be illustrated by an giraffe's neck stretching to reach higher leaves in the trees. This would cause giraffes' longer necks to be passed on to their offspring who would then grow even taller.
Lamarck, a French Zoologist from France, presented an innovative idea 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 opinion, living things had evolved from inanimate matter through the gradual progression of events. Lamarck was not the first to propose this, but he was widely considered to be the first to offer the subject a comprehensive and general treatment.
The predominant story is that Charles Darwin's theory on evolution by natural selection and Lamarckism were competing in the 19th Century. Darwinism eventually triumphed, leading to the development of what biologists now refer to as the Modern Synthesis. The theory argues that acquired traits are passed down from generation to generation and instead argues that organisms evolve through the selective influence of environmental factors, including Natural Selection.
Lamarck and his contemporaries endorsed the notion that acquired characters could be passed down to the next generation. However, this idea was never a major part of any of their theories on evolution. This is largely due to the fact that it was never tested scientifically.
It's been over 200 year since Lamarck's birth and in the field of age genomics there is a growing evidence base that supports the heritability acquired characteristics. This is referred to as "neo Lamarckism", or more commonly epigenetic inheritance. It is a version of evolution that is as valid as the more well-known Neo-Darwinian model.
Evolution by adaptation
One of the most widespread misconceptions about evolution is that it is a result of a kind of struggle for survival. This notion is not true and ignores other forces driving evolution. The struggle for survival is more accurately described as a struggle to survive in a specific environment, which can include not just other organisms, but also the physical environment.
To understand how evolution operates, it is helpful to consider what adaptation is. The term "adaptation" refers to any specific feature that allows an organism to survive and reproduce within its environment. It can be a physiological structure, such as feathers or fur or a behavior, such as moving into the shade in the heat or leaving at night to avoid the cold.
The ability of an organism to draw energy from its surroundings and interact with other organisms, as well as their physical environment is essential to its survival. The organism must possess the right genes to produce offspring and be able find sufficient food and resources. The organism must also be able to reproduce itself at a rate that is optimal for its niche.
These factors, along with mutation and gene flow can result in a change in the proportion of alleles (different types of a gene) in the gene pool of a population. This shift in the frequency of alleles can lead to the emergence of new traits and eventually new species as time passes.
A lot of the traits we admire in animals and plants are adaptations, such as the lungs or gills that extract oxygen from the air, feathers or fur to provide insulation and long legs for running away from predators, and camouflage to hide. However, a complete understanding of adaptation requires attention to the distinction between the physiological and behavioral traits.
Physical characteristics like the thick fur and gills are physical traits. Behavioral adaptations are not an exception, for instance, the tendency of animals to seek out companionship or move into the shade during hot temperatures. It is important to remember that a insufficient planning does not cause an adaptation. Failure to consider the effects of a behavior even if it seems to be logical, can make it inflexible.
