What is Free Evolution?
Free evolution is the notion that natural processes can cause organisms to develop over time. This includes the emergence and development of new species.
Many examples have been given of this, 에볼루션 코리아 including various varieties of fish called sticklebacks that can be found in salt or fresh water, and walking stick insect varieties that favor specific host plants. These mostly reversible traits permutations cannot explain fundamental changes to the body's basic plans.
Evolution through Natural Selection
Scientists have been fascinated by the development of all the living creatures that live on our planet for centuries. Charles Darwin's natural selection theory is the most well-known explanation. This is because individuals who are better-adapted have more success in reproduction and survival than those who are less well-adapted. Over time, the population of well-adapted individuals becomes larger and eventually creates an entirely new species.
Natural selection is a process that is cyclical and involves the interaction of three factors: variation, reproduction and inheritance. Variation is caused by mutation and sexual reproduction both of which enhance the genetic diversity of the species. Inheritance is the transfer of a person's genetic characteristics to the offspring of that person, which includes both recessive and dominant alleles. Reproduction is the production of fertile, viable offspring, which includes both asexual and sexual methods.
All of these elements must be in harmony to allow natural selection to take place. For example the case where the dominant allele of one gene can cause an organism to live and reproduce more often than the recessive allele, 에볼루션카지노사이트 the dominant allele will become more common within the population. If the allele confers a negative advantage to survival or decreases the fertility of the population, it will disappear. The process is self-reinforcing, 에볼루션 게이밍 which means that an organism with a beneficial characteristic will survive and reproduce more than an individual with a maladaptive characteristic. The greater an organism's fitness which is measured by its ability to reproduce and survive, is the greater number of offspring it can produce. Individuals with favorable traits, like having a longer neck in giraffes or bright white patterns of color in male peacocks, are more likely to be able to survive and create offspring, 에볼루션바카라사이트 and thus will become the majority of the population over time.
Natural selection is only a force for populations, not individuals. This is an important distinction from the Lamarckian theory of evolution which argues that animals acquire characteristics through use or neglect. For example, if a animal's neck is lengthened by reaching out to catch prey and its offspring will inherit a more long neck. The differences in neck size between generations will continue to grow until the giraffe is no longer able to reproduce with other giraffes.
Evolution by Genetic Drift
Genetic drift occurs when alleles from the same gene are randomly distributed within a population. Eventually, one of them will attain fixation (become so widespread that it is unable to be eliminated through natural selection) and other alleles fall to lower frequencies. In the extreme it can lead to one allele dominance. Other alleles have been virtually eliminated and heterozygosity decreased to a minimum. In a small group it could result in the complete elimination the recessive gene. This scenario is called the bottleneck effect. It is typical of an evolutionary process that occurs when the number of individuals migrate to form a group.
A phenotypic 'bottleneck' can also occur when the survivors of a catastrophe such as an outbreak or mass hunt event are concentrated in a small area. The survivors will share a dominant allele and thus will have the same phenotype. This situation might be caused by a conflict, earthquake or even a cholera outbreak. Whatever the reason the genetically distinct population that remains is susceptible to genetic drift.
Walsh Lewens, Walsh and Ariew define drift as a deviation from the expected values due to differences in fitness. They provide the famous case of twins that are genetically identical and have exactly the same phenotype. However one is struck by lightning and dies, while the other lives to reproduce.
This kind of drift can play a very important role in the evolution of an organism. However, it's not the only method to evolve. Natural selection is the main alternative, in which mutations and migration maintain phenotypic diversity within a population.
Stephens asserts that there is a huge difference between treating the phenomenon of drift as an agent or cause and treating other causes like migration and selection mutation as causes and forces. Stephens claims that a causal process explanation of drift permits us to differentiate it from the other forces, and this distinction is essential. He further argues that drift has both an orientation, i.e., it tends to eliminate heterozygosity. It also has a size which is determined based on 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, commonly referred to as "Lamarckism" is based on the idea that simple organisms evolve into more complex organisms by taking on traits that result from an organism's use and disuse. Lamarckism can be demonstrated by a giraffe extending its neck to reach higher levels of leaves in the trees. This would cause the longer necks of giraffes to be passed on to their offspring who would then grow even taller.
Lamarck was a French Zoologist. In his opening lecture for his course on invertebrate zoology at the Museum of Natural History in Paris on 17 May 1802, he presented an innovative concept that completely challenged previous thinking about organic transformation. In his opinion, living things had evolved from inanimate matter through an escalating series of steps. Lamarck wasn't the only one to suggest this but he was thought of as the first to give the subject a thorough and general explanation.
The dominant story is that Charles Darwin's theory on evolution by natural selection and Lamarckism fought in the 19th Century. Darwinism ultimately prevailed which led to what biologists call the Modern Synthesis. The theory argues that acquired traits can be passed down through generations and instead, it claims that organisms evolve through the selective action of environment elements, like Natural Selection.
Lamarck and his contemporaries endorsed the notion that acquired characters could be passed on to the next generation. However, this idea was never a key element of any of their evolutionary theories. This is partly due to the fact that it was never validated scientifically.
It has been more than 200 year since Lamarck's birth and in the field of genomics, there is a growing evidence-based body of evidence to support the heritability acquired characteristics. This is also known as "neo Lamarckism", or more generally epigenetic inheritance. This is a version that is just as valid as the popular neodarwinian model.
Evolution through Adaptation
One of the most popular misconceptions about evolution is being driven by a struggle to survive. This notion is not true and overlooks other forces that drive evolution. The struggle for existence is better described as a fight to survive in a certain environment. This can include not only other organisms but also the physical environment itself.
To understand how evolution functions it is beneficial to think about what adaptation is. It refers to a specific characteristic that allows an organism to survive and reproduce within its environment. It can be a physiological feature, such as fur or feathers, or a behavioral trait such as a tendency to move to the shade during hot weather or coming out at night to avoid 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 have the right genes for producing offspring and to be able to access sufficient food and resources. Furthermore, the organism needs to be capable of reproducing itself in a way that is optimally within its niche.
These factors, together with gene flow and mutation result in a change in the proportion of alleles (different types of a gene) in the population's gene pool. The change in frequency of alleles can result in the emergence of novel traits and eventually, new species over time.
A lot of the traits we admire in animals and plants are adaptations, like lungs or gills to extract oxygen from the air, fur or feathers for insulation and long legs for running away from predators and camouflage for hiding. However, a proper understanding of adaptation requires paying attention to the distinction between the physiological and behavioral traits.
Physiological adaptations like thick fur or gills, are physical traits, while behavioral adaptations, like the tendency to seek out companions or to retreat into the shade in hot weather, are not. It is important to note that lack of planning does not result in an adaptation. In fact, failing to think about the implications of a behavior can make it unadaptable despite the fact that it may appear to be logical or even necessary.
