What did Darwin's theory of evolution provide that earler theories of evolution had not?
Darwin was by no means the first person to come up with a theory of evolution. However, he was the first person provide a mechanism by which evolution could occur. He called this natural selection and is essentially the way in which individuals with characterisitcs that better suit their environment survive and ones which don't die out. Therefore, eventually the whole species will possess these advantageous characteristics and evolution will have occured.
How is natural selection and evolution linked?
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
What are the 3 key points in Neo-Darwinism?
Natural selection is the main mechanism driving evolution by favoring individuals with advantageous traits. Genetic mutations and recombination provide the raw material for variation upon which natural selection acts. Evolution occurs gradually over long periods of time through the accumulation of small genetic changes in populations.
How is change by natural selection different from change due to a mutation?
Change by natural selection occurs when certain traits provide a survival or reproductive advantage in a given environment, leading to those traits becoming more common in a population over generations. In contrast, a mutation is a random change in an organism's DNA that can introduce new traits. While mutations are the source of genetic variation, natural selection acts on that variation, favoring beneficial mutations and weeding out harmful ones. Thus, mutations are the raw material for evolution, while natural selection is the mechanism that drives adaptive change.

Did Charles Darwin coin the concept of evolution?
Charles Darwin did not coin the concept of evolution, but he is famously known for developing the theory of evolution by natural selection. Evolution as a concept had been discussed by earlier scientists and philosophers before Darwin. Darwin's contribution was to provide a comprehensive explanation for how evolution occurs through the mechanism of natural selection.
What did Darwin's publication provide for the scientific community that had been lacking in previously published works about evolution?
As you said, previously published works were well acquainted with the process of evolution, but Darwin gave evolution a mechanism of action through his theory of evolution by natural selection in his 1859 publication.Natural selection is the nonrandom survival and reproductive success of randomly varying organisms.
Is NOT a component of the theory of evolution by natural selection?
Acquired traits. The theory of evolution by natural selection focuses on inherited traits that provide a reproductive advantage. Acquired traits, which are not genetically determined, do not play a direct role in this process.
What is mutation and how is it related to evolution?
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Why should people believe in evolution?
People should not " believe in " evolution but accept that evolution, the change in allele frequency over time in a population of organisms, is fact. The also need to consider the theory of evolution by natural selection, which explains much about evolution, as one of the most well supported explanatory theories in science. Then they would, if they are intellectually honest, come to accept not only the fact of evolution but the theory of evolution by natural selection. " Believe in " is a term one uses when one can provide no supporting evidence for one's concepts and this does not include evolution and the theory of evolution by natural selection.

What does evolution provide the raw materials for?
Selection by death.
What are the 3 key points in Neo-Darwinism?
Natural selection is the main mechanism driving evolution by favoring individuals with advantageous traits. Genetic mutations and recombination provide the raw material for variation upon which natural selection acts. Evolution occurs gradually over long periods of time through the accumulation of small genetic changes in populations.
Can evolution create new structures?
Yes, evolution can create new structures through the process of genetic mutations and natural selection. Over time, mutations can lead to the development of new traits and structures that may provide a survival advantage. These advantageous traits can then become more common in a population through natural selection.
What is a process that explains how evolution occurs?
One process that explains how evolution occurs is natural selection. This process involves certain traits becoming more common in a population over time because they provide a reproductive advantage, leading to gradual changes in the population's characteristics. Additionally, genetic mutations also play a role in evolution by introducing new variations that can be subjected to natural selection.
