How do monkey flowers near mines show that natural selection causes evolution?

Copper tolerance in monkey flowers is an example of a direct observation of evolution. Natural selection favors the survival and reproduction of copper-tolerant plants in copper-contaminated soils. Therefore, the allele for copper tolerance must have been present in some plants when the soil became contaminated. Because copper tolerance provides no benefit to plants in uncontaminated soils, the trait is not as common in plant populations growing outside the contaminated area. they had sex.

Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
What is the process called where the environment in which a species lives causes a change to the collective genes of that species?
Natural selection, which is the mechanism for evolution.
How does adaptation fit into natural selection?
Adaptation and evolution all have to do with how an animal or a species depend on there environment. Adaptation is how the species adapts to there environment.Adaptation is caused by evolution by natural selection.
Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
How do natural selection cloning and selective breeding lead to evolutionary change?
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
Which force of evolution makes a population more alike?
Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Mutation, genetic drift, gene flow and the driver of adaptive change, natural selection.
What process causes evolution?
Mainly natural selection, but drift, flow and endosymbiosis are all factors too, just to name a few.
Is natural selection a form of adaptation?
Natural selection is what causes adaptation.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
What are the mechanisms of evolution?
There are several mechanisms for evolution. The first (and most important) being natural selection, which plays off random mutations. Genetic drift is also another important aspect of evolution. EDIT: It depends on what you mean by "mechanism." Mutations are thought to be the mechanism that causes the change in DNA, then natural selection and Gentic drift take over. Unfortunately, mutations do not hold up and evolution is ultimately left without a mechanism.
