The Theory of Evolution
|
||||
|
||||
The theory of evolution is based on the fact certain traits are passed on more often than others. These characteristics make it easier to live and reproduce for individuals, so their number tends to increase with time.
|
||||
|
||||
Scientists understand now how this process functions. A study of the clawed-frog showed that duplicate genes can serve different purposes.
|
||||
|
||||
Evolution is a natural process
|
||||
|
||||
The natural process that leads to the evolution of organisms most adjusted to their environment is referred to as "natural selection." It's one of the primary processes of evolution, alongside mutation or migration as well as genetic drift. The ones with traits that aid in reproduction and survival will be more likely to pass these traits to their offspring. This causes gradual changes in the gene frequency over time. This leads to new species being born and existing ones being altered.
|
||||
|
||||
In the 19th century, Charles Darwin formulated a scientific theory that explained how biological organisms developed over time. The theory is based on the notion that more offspring than are able to be able to survive are born and that these offspring compete for resources in their environments. This results in an "evolutionary struggle" in which those who have the most desirable traits prevail and others are eliminated. The remaining offspring transmit the genes responsible for these beneficial traits to their offspring which gives them an advantage over other members of the same species. As time passes, the number of organisms with these beneficial traits grows.
|
||||
|
||||
However, it's difficult to understand how natural selection can create new traits when its primary purpose is to eliminate inequities individuals. Additionally, the majority of natural selections decrease genetic variation within populations. As a result, it is unlikely that natural selection will produce the emergence of new traits unless other forces are in play.
|
||||
|
||||
Mutation, genetic drift and migration are the primary forces of evolution that alter gene frequencies and cause evolution. Sexual reproduction and the fact that every parent transmits half their genes to each child increases the speed of these processes. These genes, also known as alleles, may be present at different frequency between individuals belonging to the same species. The allele frequencies determine whether a trait is dominant or recessive.
|
||||
|
||||
In simplest terms, a mutation is a change in the DNA structure of an organism's code. The mutation causes some cells to develop and grow into an entirely different organism, while others don't. Mutations can increase the frequency of alleles that already exist or create new ones. The new alleles are then passed to the next generation and become dominant phenotypes.
|
||||
|
||||
Evolution is built on natural selection
|
||||
|
||||
Natural selection is a straightforward mechanism that causes populations of living things to change over time. It is the result of heritable phenotypic variation and differential reproduction. These causes create an environment where people with positive characteristics are more likely survive and reproduce more than those who don't. Over time this process results in an alteration in the gene pool, making it more closely aligned with the environment in which they live. This is the basic concept of Darwin's "survival of the fittest."
|
||||
|
||||
This process is based on the notion that people adapt to their surroundings by displaying various traits. Individuals with adaptable traits are more likely to survive and reproduce, which means they are more likely to produce more offspring. BioMed Central states that this will eventually lead to the trait to spread across the population. At some point all of the people will have the trait, and the population will change. This is referred to as evolution.
|
||||
|
||||
Those with less-adaptive traits will die or will not be able to produce offspring, and their genes won't be passed on to future generations. In time, genetically modified organisms are more likely to become dominant in the population. They may also evolve into new species. However, this isn't a guarantee. The environment may change abruptly making the changes in place.
|
||||
|
||||
Sexual selection is another factor that influences evolution. Some traits are favored because they increase the odds of a person mating with another. This can lead to some odd phenotypes like brightly colored feathers in birds, or the massive antlers of deer. These phenotypes may not be beneficial to the organism but they can boost its chances of survival as well as reproduction.
|
||||
|
||||
Another reason that some students do not understand natural selection is because they mistake it for soft inheritance. While soft inheritance isn't an essential condition for evolution, it is often an important element of it. This is due to the fact that it allows for the random modification of DNA as well as the creation of genetic variants that are not immediately beneficial to the organism. These mutations are later utilized as raw materials by natural selection.
|
||||
|
||||
Evolution is based on genetics
|
||||
|
||||
Evolution is a natural process that causes changes in the traits inherited of a species over time. It is influenced by a variety of factors, including mutation, genetic drift, gene flow, and horizontal gene transfer. The relative frequency of alleles within a population can influence the development. This permits the selection of traits that are beneficial in the new environment. The theory of evolutionary change is a fundamental idea in biology and has profound implications for our understanding of life.
|
||||
|
||||
Darwin's theories, when paired with Linnaeus' concepts of relatedness and Lamarck's theories about inheritance, transformed the idea of how traits are passed down from parent to offspring. Instead of parents passing on inherited characteristics through use or disuse, Darwin argued that they were favored or [에볼루션 슬롯](https://evolutionkr.kr/) disfavored by the environment in which they lived and passed that knowledge on to their offspring. He called this natural selection and in his book The Origin of Species he explained how this could lead the development of new types of species.

|
||||
Genetic changes, or mutations, occur randomly in the DNA of cells. These mutations can cause many phenotypic traits, from hair color to eye color, and are influenced by a variety of environmental factors. Certain phenotypic traits are controlled by multiple genes and some have more than two alleles, for instance, blood type (A B, or O). The combination of the Darwinian ideas about evolution with Mendel's theories of genetics is referred to as the Modern Synthesis, and it is the framework that brings together macroevolutionary changes in fossil records along with microevolutionary processes, such as genetic mutation and the selection of traits.
|
||||
|
||||
Macroevolution takes a very long time and can only be seen in fossil records. However, microevolution is a more rapid process that can be seen in living organisms today. Microevolution is driven by genetic selection and mutation which are smaller scales than macroevolution. It can also be increased through other mechanisms, like gene flow or horizontal gene transfer.
|
||||
|
||||
Evolution is based upon chance
|
||||
|
||||
Evolutionists have used for years the argument that evolution is an uncontrolled process. This argument is faulty and it is important to know the reason. The argument confuses randomness and contingency. This error is a result of a misreading of the nature of biological contingency as described by Stephen Jay Gould. He believed that genetic information doesn't grow randomly, but also is influenced by past events. He relied on the fact that DNA is an incarnation of genes which are dependent on other molecules. In other terms, there is a causality in every biological process.
|
||||
|
||||
The argument is also flawed because of its reliance on the physical laws and the application of science. These assertions aren't just inherently untrue, but they are also erroneous. Furthermore, the practice of science presupposes a causal determinism that isn't sufficient to account for all natural events.

||||

In his book, Brendan Sweetman aims to provide a balanced, generally accessible introduction to the relationship between evolutionary theory and Christian theism. He isn't a flashy author, but rather a patient one, which fits his objectives, which include detaching the scientific status from the implications for the faith of evolutionary theory.
|
||||
|
||||
Although the book isn't as comprehensive as it could be but it does provide an informative overview of the issues in this debate. It also demonstrates that the theories of evolution are well-proven and widely accepted. They are suitable for rational approval. However the book is less than convincing on the issue of whether God has any influence on evolution.
