What else can I help you with?
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
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 is genetic variation measured with?
Variation of quantative characters such as littersize and lifetime reproductive output. Variation in protein sequence. Variation in the non-coding regions of DNA
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.
How is variation related to evolution?
The more variation there is in a group of specimens, the more evolution can occur between them.

What scriptures are there about evolution?
Religious scriptures about Darwinian evolution by variation and selection? None that I am aware of.
What is the central force driving evolution?
Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
Which of the following is necessary for evolution to occur?
Genetic variation is necessary for evolution to occur, as it provides the raw material for natural selection to act upon. This variation can arise from mutations, genetic recombination, or gene flow.
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.
Is mutation an important part of the process of evolution?
Yes, mutations are crucial for the process of evolution as they introduce genetic variation into populations. This variation allows for natural selection to act upon, leading to the adaptation and evolution of species over time.
Does the environment dictate only the direction and extent of evolution?
The environment is the ' natural selector ' of all variation. This is evolution.
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
How do genetic variation and environmental factors influence evolution?
Genetic variation drives evolution by providing the raw material for natural selection to act upon, allowing organisms to adapt to changing environments. Environmental factors can influence which traits are favored, shaping the direction of evolution. Together, genetic variation and environmental factors contribute to the diversity of life on Earth through the process of evolution.
What is the difference between variation and evolution?
Variation refers to differences in traits within a population, such as height or eye color. Evolution is the process by which populations of organisms change over time through the accumulation of adaptations, driven by factors like natural selection and genetic drift. Variation provides the raw material for evolution to occur.
Why are chimpanzees brown and black?
evolution. variation and natural selection. DNA!!!!
