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.
What else can I help you with?
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.
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).
How do monkey flowers near mines show that the natural selection causes evolution?
Monkey flowers near mines exhibit variations in traits, such as flower color and chemical composition, that allow them to thrive in contaminated soils. Those with adaptations that reduce toxic metal uptake or enhance survival in harsh conditions are more likely to reproduce and pass on their advantageous traits to the next generation. This process of natural selection leads to an evolutionary change in the population over time, demonstrating how environmental pressures can shape species. Thus, the observed adaptations in monkey flowers serve as a clear example of evolution driven by natural selection.
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 question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Is adaptation a cause of natural selection?
No, it's exactly the other way around: natural selection causes adaptation.
What process causes adaptations to evolve?
Natural selection
What factor of natural selection causes competition?
Overproduction
what causes natural selection to occur?
the presence of predators
What process causes evolution?
Evolution is driven by natural selection, genetic drift, gene flow, and mutations. These processes lead to changes in the genetic makeup of populations over generations, resulting in the accumulation of adaptations that help species survive and reproduce in their environment.
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.
