Explain the role of mutations in evolution?
Mutations are the material upon which natural selection acts. Evolution is a two sided coin. One side is mutation; the other side is natural selection. Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.
Who created the modern theory of evolution?
There are several theories to explain evolution, though evolution itself is not a theory. Perhaps the best known is Darwin's theory through natural selection.
How does natural selection explain how organisms have changed over time?
Variation within species allows death to be a selector of survivors.
How did Charles Darwin explain inherited variation and artificial selecton?
Darwin said that artificial selection was when nature provided the variation, and humans selected those variations that they found useful. Inherited variations are differences that are passed from parents to offspring
What are the differences between Darwin's theory of evolution and conflicting theories?
It is no longer Darwin's theory, as Darwin has been dead about 130 years. There are no credible alternatives to the modern theory of evolution by natural selection. So, the differences is; the theory of evolution by natural selection is supported by myriad lines of converging evidence and explains the natural phenomenon that is evolution very well. The " conflicting theories " have no evidence supporting them and explain nothing.
6 Explain why evolution by natural selection can not occur if the variation in a characteristic does not contribute to differences in fitness?
If there is not reproductive fitness conveyed by a variant trait, then natural selection has nothing to select and nothing to promote into the populational gene pool.
How did Darwin explain why Galapagos species had different adaptions and similar South American species?
Define the term Variation and natural selection how do they work together to help cause evolution
Are there other theories that explain the same event as evolution theory?
No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.

Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.
Explain the role of variation in evolution?
Variation plays a role in the process of natural selection because it keeps things mixed up. This is necessary so that one thing doesn't overtake another, ruling it out. If things are equal, one can't overrule another.
What can the theory of evolution by natural selection explain about a population?
How it can change in response to its enviroment
What does evolution explain about living things?
It explains that all known species are related to one another through shared ancestry. It explains that all known life continuously evolves and adapts through reproductive variation and natural selection.
Who created the modern theory of evolution?
There are several theories to explain evolution, though evolution itself is not a theory. Perhaps the best known is Darwin's theory through natural selection.
What two ideas did Darwin use to explain evolution?
natural selection and common descent
What did Darwin assert in his book On The Origin of Species as the mechanism of evolution?
Due to genes and mutations, organisms show variation within a species. Changes in the environment can put a selective pressure on the species - certain mutations may be more beneficial, therefore more individuals with that mutation will exist, as they survive and breed. This process is called Natural Selection.
What does Darwin theory of evolution explain?
The theory of evolution by natural selection. It explains evolution; the change in allele frequency over time in a population of organisms. Why organisms change over time in differing environments.
Who gave the theory of evolution?
There is no " theory of evolution " as evolution is a fact. The theory is; the theory of evolution by natural selection and explains much about the fact of evolution. Charles Robert Darwin and Alfred Russel Wallace come up with the theory of evolution by natural selection, though natural selection is a phrase coined by Darwin.
