Evolution by natural selection works best on populatin having no variation?
Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.
What are some important questions to ask about evolution?
Some important questions to ask about evolution include: How does natural selection work? What evidence supports the theory of evolution? How does genetic variation contribute to evolution? What role do environmental factors play in driving evolution? How does the fossil record provide insights into evolutionary history?
Evolution can occur at different rates however for evolution to occur there must be?
variation in the traits of organisms, heredity (the ability to pass on those traits to offspring), and differential survival and reproduction based on those traits (natural selection). These elements work together to drive the process of evolution over time.
How does natural selection and variation work together to explain evolution?
Natural selection acts on the variation present in a population, favoring individuals with traits that are better suited for their environment and allowing them to survive and reproduce more successfully. Over time, these advantageous traits become more common in the population through the process of evolution, as less-fit traits are selected against.
Why is variation important for natural selection to occur effectively?
Variation is important for natural selection because it provides the raw material for evolution to work with. Without variation in traits among individuals, there would be no differences for natural selection to act upon. This variation allows some individuals to be better suited to their environment, increasing their chances of survival and reproduction, while less well-adapted individuals are less likely to survive and pass on their genes. Over time, this process leads to the evolution of populations with traits that are better suited to their environment.
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
How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.

Did Darwin believe that mutations are the main cause for evolution?
At the time that Darwin published his work the theory of genetic transfer of characteristics by Gregor Mendel had not been published. As a consequence genetic theory, mutations, recessive characteristics and allof those issues would be unknown.
Why was variation the weakest concept in Darwin's theory?
Variation?!?! That was an obvious observation of naturalists that opposed Darwin's concepts totally. Unless you mean the heritability that leads to variation? Explaining that variation was the problem. Creationists of the time explained this by positing god's whimsy in designing his species, but this was shown to be nonsense as natural processes are at work in variation and this can be shown experimentally. The concept of natural selection explained how that natural variation was selected on beneficial traits. What Darwin did not understand is how that variation was passed on to progeny. His explanation was wrong.
The weakest concept in Darwin's theory was variation why?
Variation was not the weakest concept in Darwin's theory. In fact, variation is a key component of natural selection, as it provides the raw material for evolution to work on. Individual variations within a population allow some organisms to survive and reproduce more successfully than others, leading to changes in the gene pool over time.
How does variation work in natural selection?
Answer 1If you have group of a species with dark skin and another group with light skin in an environment with much direct sunlight, the dark skinned gene group will be selected as the dark skin (with more melanin) is protective in that sunlit environment. If the environment is northern, the lighter skin gene will become more common. This variation will be a help in natural selection.Answer 2Genetic variation, or reproductive variation, are the mechanisms that cause one sibling to be slightly different from another. It is this difference that allows natural selection to work, for there may be various reasons, to do with these differences, why one sibling is more successful in producing offspring than the other.
What was Charles Darwin's theory on the driving force of evolution called?
Darwin claimed it was the process of natural selection that drove evolution. However this is incomplete, without both a process that creates variation and the process of natural selection evolution could not work. There are many processes that create variation (e.g. mutation, crossover, transformation, infection, conjugation, polyploidy).
