What is Free Evolution?

Free evolution is the idea that natural processes can cause organisms to evolve over time. This includes the appearance and growth of new species.

Many examples have been given of this, including various varieties of stickleback fish that can be found in fresh or salt water and 에볼루션 코리아 (Pattern-Wiki.Win) walking stick insect varieties that prefer specific host plants. These mostly reversible trait permutations however, are not able to explain fundamental changes in body plans.

Evolution by Natural Selection

The evolution of the myriad living organisms on Earth is a mystery that has fascinated scientists for decades. The most widely accepted explanation is Charles Darwin's natural selection process, an evolutionary process that occurs when individuals that are better adapted survive and reproduce more successfully than those less well adapted. As time passes, a group of well-adapted individuals expands and eventually forms a whole new species.

Natural selection is an ongoing process that is characterized by the interaction of three factors: variation, inheritance and reproduction. Sexual reproduction and mutation increase genetic diversity in the species. Inheritance is the term used to describe the transmission of a person’s genetic traits, including both dominant and recessive genes, to their offspring. Reproduction is the process of producing fertile, viable offspring. This can be accomplished via sexual or asexual methods.

All of these factors must be in balance to allow natural selection to take place. If, for instance the dominant gene allele makes an organism reproduce and last longer than the recessive gene The dominant allele becomes more common in a population. If the allele confers a negative advantage to survival or reduces the fertility of the population, it will be eliminated. This process is self-reinforcing meaning that an organism with an adaptive trait will survive and reproduce much more than one with a maladaptive characteristic. The higher the level of fitness an organism has which is measured by its ability to reproduce and survive, is the greater number of offspring it can produce. Individuals with favorable characteristics, like having a longer neck in giraffes and bright white color patterns in male peacocks are more likely survive and produce offspring, so they will make up the majority of the population in the future.

Natural selection only affects populations, not on individual organisms. This is an important distinction from the Lamarckian theory of evolution which claims that animals acquire characteristics through use or disuse. If a giraffe extends its neck to catch prey and the neck grows larger, then its children will inherit this characteristic. The differences in neck size between generations will continue to increase until the giraffe is unable to breed with other giraffes.

Evolution through Genetic Drift

In genetic drift, alleles within a gene can be at different frequencies in a group through random events. In the end, one will attain fixation (become so common that it is unable to be eliminated through natural selection) and the other alleles drop to lower frequencies. This can lead to a dominant allele in the extreme. The other alleles are eliminated, and heterozygosity is reduced to zero. In a small group, this could result in the complete elimination the recessive gene. Such a scenario would be known as a bottleneck effect and it is typical of the kind of evolutionary process that takes place when a large amount of individuals migrate to form a new population.

A phenotypic bottleneck may occur when survivors of a catastrophe, such as an epidemic or 에볼루션카지노 a mass hunt, are confined within a narrow area. The survivors will share an allele that is dominant and will share the same phenotype. This situation might be caused by a war, an earthquake or even a cholera outbreak. The genetically distinct population, if it remains, could be susceptible to genetic drift.

Walsh, Lewens, 에볼루션 게이밍 and Ariew use a "purely outcome-oriented" definition of drift as any departure from expected values for differences in fitness. They cite the famous example of twins that are genetically identical and share the same phenotype. However, 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. It is not the only method for evolution. Natural selection is the main alternative, where mutations and 에볼루션 룰렛 에볼루션 코리아; click4R.Com, migrations maintain the phenotypic diversity in the population.

Stephens asserts that there is a big distinction between treating drift as a force or a cause and treating other causes of evolution, such as mutation, selection and migration as causes or causes. He claims that a causal process account of drift permits us to differentiate it from the other forces, and that this distinction is vital. 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

When students in high school take biology classes, they are frequently 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 through inheriting characteristics that are a product of the organism's use and misuse. Lamarckism is typically illustrated by an image of a giraffe that extends its neck longer to reach leaves higher up in the trees. This would cause giraffes to give their longer necks to offspring, which then become taller.

Lamarck the French Zoologist from France, presented an idea that was revolutionary in his opening lecture at the Museum of Natural History of Paris. He challenged the conventional wisdom on organic transformation. According to Lamarck, living things evolved from inanimate materials by a series of gradual steps. Lamarck was not the only one to suggest that this could be the case but he is widely seen as having given the subject its first general and comprehensive analysis.

The most popular story is that Lamarckism grew into an opponent to Charles Darwin's theory of evolutionary natural selection, and that the two theories battled out in the 19th century. Darwinism eventually prevailed, leading to the development of what biologists call the Modern Synthesis. The Modern Synthesis theory denies the possibility that acquired traits can be acquired through inheritance and instead, it argues that organisms develop through the selective action of environmental factors, such as natural selection.

Lamarck and his contemporaries endorsed the idea that acquired characters could be passed on to the next generation. However, this notion was never a key element of any of their theories on evolution. This is partly due to the fact that it was never validated scientifically.

But it is now more than 200 years since Lamarck was born and in the age of genomics, there is a large amount of evidence that supports the heritability of acquired characteristics. This is also known as "neo Lamarckism", or more generally epigenetic inheritance. This is a variant that is as reliable as the popular neodarwinian model.

Evolution by Adaptation

One of the most commonly-held misconceptions about evolution is its being driven by a fight for survival. This view is inaccurate and overlooks other forces that drive evolution. The fight for survival is more accurately described as a struggle to survive in a specific environment. This can include not just other organisms as well as the physical environment.

Understanding how adaptation works is essential to understand evolution. It refers to a specific feature that allows an organism to live and reproduce in its environment. It can be a physical feature, such as feathers or fur. Or it can be a characteristic of behavior, like moving into the shade during hot weather or escaping the cold at night.

The survival of an organism is dependent on its ability to extract energy from the environment and to interact with other organisms and their physical environments. The organism must have the right genes to create offspring, and must be able to access sufficient food and other resources. Moreover, the organism must be capable of reproducing at a high rate within its environmental niche.

These factors, together with mutations and gene flow, can lead to changes in the proportion of different alleles in the population's gene pool. As time passes, this shift in allele frequencies can result in the emergence of new traits, and eventually new species.

Many of the features we admire in animals and plants are adaptations. For instance lung or gills that extract oxygen from the air, fur and feathers as insulation, long legs to run away from predators and camouflage for hiding. However, a complete understanding of adaptation requires a keen eye to the distinction between the physiological and behavioral characteristics.

Physiological adaptations, such as thick fur or gills are physical traits, whereas behavioral adaptations, like the tendency to seek out companions or to move into the shade in hot weather, are not. In addition, it is important to remember that lack of planning is not a reason to make something an adaptation. A failure to consider the implications of a choice, even if it appears to be logical, can cause it to be unadaptive.
