What is Free Evolution?
Free evolution is the idea that natural processes can cause organisms to develop over time. This includes the emergence and development of new species.
Numerous examples have been offered of this, such as different varieties of fish called sticklebacks that can live in either salt or fresh water, and walking stick insect varieties that favor specific host plants. These mostly reversible traits permutations do not explain the fundamental changes in basic body plans.
Evolution by Natural Selection
Scientists have been fascinated by the development of all living organisms that inhabit our planet for ages. The most widely accepted explanation is Charles Darwin's natural selection process, an evolutionary process that is triggered when more well-adapted individuals live longer and reproduce more successfully than those that are less well adapted. Over time, a community of well adapted individuals grows and eventually becomes a new species.
Natural selection is an ongoing process that is characterized by the interaction of three factors that are 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 transfer of a person's genetic characteristics to the offspring of that person that includes recessive and dominant alleles. Reproduction is the production of fertile, viable offspring which includes both asexual and sexual methods.
Natural selection only occurs when all the factors are in harmony. If, for example the dominant gene allele causes an organism reproduce and survive more than the recessive gene, then the dominant allele will become more prevalent in a 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 that has an adaptive characteristic will live and reproduce much more than one with a maladaptive characteristic. The more offspring that an organism has, the greater its fitness which is measured by its capacity to reproduce and survive. People with desirable traits, like longer necks in giraffes and bright white patterns of color 에볼루션 바카라 무료바카라 에볼루션에볼루션 바카라 사이트 (use Metooo) in male peacocks are more likely survive and have offspring, so they will become the majority of the population over time.
Natural selection only affects populations, not individual organisms. This is a major distinction from the Lamarckian theory of evolution that states that animals acquire traits due to usage or inaction. For instance, if a Giraffe's neck grows longer due to reaching out to catch prey its offspring will inherit a more long neck. The length difference between generations will continue until the giraffe's neck becomes too long that it can not breed with other giraffes.
Evolution by Genetic Drift
In genetic drift, the alleles at a gene may attain different frequencies within a population by chance events. Eventually, one of them will attain fixation (become so common that it can no longer be eliminated through natural selection) and other alleles fall to lower frequency. In the extreme, this leads to one allele dominance. The other alleles are essentially eliminated, and heterozygosity falls to zero. In a small group it could result in the complete elimination of the recessive gene. This scenario is known as a bottleneck effect and it is typical of the kind of evolutionary process when a large amount of individuals move to form a new population.
A phenotypic bottleneck can also occur when survivors of a disaster such as an outbreak or mass hunting event are concentrated in an area of a limited size. The survivors will have a dominant allele and thus will share the same phenotype. This could be caused by earthquakes, war or even a plague. Regardless of the cause the genetically distinct group that remains is susceptible to genetic drift.
Walsh Lewens, Lewens, and Ariew employ Lewens, Walsh, and Ariew use a "purely outcome-oriented" definition of drift as any departure from expected values for differences in fitness. They provide a well-known instance of twins who are genetically identical, share identical phenotypes and yet one is struck by lightning and dies, while the other lives and reproduces.
This type of drift is crucial in the evolution of an entire species. But, it's not the only way to progress. Natural selection is the primary alternative, in which mutations and migrations maintain the phenotypic diversity of the population.
Stephens argues that there is a big 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. He argues that a causal process account of drift permits us to differentiate it from these other forces, and that this distinction is vital. He further argues that drift has both direction, i.e., it tends towards eliminating heterozygosity. It also has a size, that is determined by population size.
Evolution by Lamarckism
Students of biology in high school are often exposed to Jean-Baptiste lamarck's (1744-1829) work. His theory of evolution, commonly called "Lamarckism is based on the idea that simple organisms evolve into more complex organisms taking on traits that result from an organism's use and disuse. Lamarckism can be illustrated by the giraffe's neck being extended to reach higher levels of leaves in the trees. This would cause the necks of giraffes that are longer to be passed to their offspring, who would grow taller.
Lamarck, a French zoologist, presented an idea that was revolutionary in his 17 May 1802 opening lecture at the Museum of Natural History of Paris. He challenged traditional thinking about organic transformation. In his opinion living things evolved from inanimate matter through an escalating series of steps. Lamarck wasn't the first to propose this but he was thought of as the first to offer the subject a comprehensive and general overview.
The dominant story is that Charles Darwin's theory of evolution by natural selection and Lamarckism fought in the 19th Century. Darwinism eventually prevailed and led to the development of what biologists refer to as the Modern Synthesis. The theory denies that acquired characteristics can be passed down through generations and instead argues organisms evolve by the selective action of environment factors, including Natural Selection.
Although Lamarck believed in the concept of inheritance through acquired characters and his contemporaries spoke of this idea however, it was not an integral part of any of their theories about evolution. This is partly because it was never scientifically validated.
But it is now more than 200 years since Lamarck was born and in the age genomics there is a vast amount of evidence to support the heritability of acquired traits. This is also known as "neo Lamarckism", or more commonly epigenetic inheritance. It is a version of evolution that is just as valid as the more well-known neo-Darwinian model.
Evolution by adaptation
One of the most common misconceptions about evolution is that it is driven by a sort of struggle for survival. This is a false assumption and overlooks other forces that drive evolution. The fight for survival is better described as a fight to survive in a specific environment. This could include not just other organisms, but also the physical environment.
Understanding the concept of adaptation is crucial to comprehend evolution. The term "adaptation" refers to any specific characteristic that allows an organism to survive and reproduce within its environment. It can be a physical structure, like feathers or fur. It could also be a trait of behavior, like moving into the shade during hot weather, or escaping the cold at night.
The capacity of a living thing to extract energy from its surroundings and interact with other organisms, as well as their physical environments is essential to its survival. The organism must possess the right genes to produce offspring, and must be able to access sufficient food and other resources. Moreover, the organism must be able to reproduce itself at an optimal rate within its environment.
These elements, in conjunction with gene flow and mutation, lead to changes in the ratio of alleles (different varieties of a particular gene) in the population's gene pool. Over time, this change in allele frequencies can result in the development of new traits and eventually new species.
Many of the characteristics we admire in animals and plants are adaptations. For instance the lungs or gills which extract oxygen from the air feathers and fur for insulation long legs to run away from predators, and camouflage to hide. However, a complete understanding of adaptation requires paying attention to the distinction between the physiological and behavioral traits.
Physiological traits like thick fur and gills are physical traits. Behavior adaptations aren't like the tendency of animals to seek out companionship or retreat into shade in hot weather. In addition it is important to note that lack of planning does not make something an adaptation. In fact, failure to think about the consequences of a behavior can make it unadaptable even though it might appear sensible or even necessary.
