Which of the following statements best describes how the process of natural selection works? Better-adapted individuals will leave behind more offspring to carry on their genes, producing a dynamic “fit” between a population and its changing environment. … Gene flow causes the frequency of the brown allele to increase.
Which of the following is the best description of natural selection?
Natural selection is the process through which populations of living organisms adapt and change. … Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.

Which statement describes how evolution through natural selection works quizlet?
Fossils indicate the periods when species existed and when they went extinct. Which statement describes how evolution through natural selection works? Individuals with successful phenotypes have an increased chance of producing viable offspring, which changes the population’s genetic structure between generations.

Which statement best describes the process of evolution? Populations can survive in different locations on earth. Environmental conditions limit the number of species on Earth.
Which of the following best describes evolution quizlet?
Which of the following best describes evolution? It is the change in heritable traits in living populations over successive generations.
Which of the following best explains the process of evolution?
Charles Darwin was a British naturalist who proposed that evolution occurs through the mechanism of natural selection. He had realized that many of the organisms were the descendants of the same species and had changed (or evolved) over time. …
Which of the following best describes the effect that natural selection might have on a species over time?
Which of the following BEST describes the effect that natural selection might have on a species over time? … Members of a species with traits that allow them to survive and reproduce in an environment will increase in population, while those without those traits will die.
Which of the following is required for the process of evolution by natural selection to occur quizlet?
The three conditions that must be met in order for natural selection to occur and result in evolutionary change are traits, inherited, and selection pressure.
What are the 3 steps to natural selection?
- Reproduction: the act or process of producing offspring. …
- Heredity: the mechanism of transmission of specific characters or traits from parent to offspring. …
- Variation in fitness of organisms.
What are the 3 components of natural selection?
The essence of Darwin’s theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur.
What are the four steps of natural selection quizlet?
- What are the 4 steps of natural selection? Overproduction. …
- Overproduction. A species produces more offspring than can survive to maturity. …
- Genetic Variation. the offspring will have some differences in appearance of behaviors. …
- Struggle To Survive. Resources are limited.
- Successful Reproduction.
What is natural selection examples?

What are the 5 stages of natural selection?
Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.
How do you explain natural selection to a child?
Natural selection is the process where organisms that are best suited to their environment survive and pass on their genetic traits in increasing number to successive generations. At the same time, organisms that are less adapted fail to survive or multiply at a lower rate, and tend to be eliminated from the ecosystem.

- More offspring are produced than can survive. Organisms are capable of producing more offspring than their environments can support. …
- Offspring vary in their heritable traits.
Is natural selection a random process?
The genetic variation on which natural selection acts may occur randomly, but natural selection itself is not random at all. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment.

Which of the following statements describes the evolution by natural selection of Mycobacterium tuberculosis bacteria in their new environment? … The drug-resistance trait is an adaptation to the environment in which human hosts travel worldwide and are exposed to new strains of bacteria.
Which statement about natural selection on early Earth is correct?
Which statement about natural selection on early Earth is correct? Natural selection could act on a population of proto-cells on early Earth, selecting for those that were stable and had self-replicating, catalytic RNA that allowed them to grow and divide to produce similar daughter proto-cells.
In what sense is natural selection more of an editing process than creating process?
In what sense is natural selection more an editing process than a creative process? Natural selection cannot create beneficial traits on demand but instead “edits” variation in a population by selection for individuals with those traits that are best suited to the current environment.
Which of the following is not a result of natural selection?
