Can natural selection occur in an individual organism?
No, natural selection operates at the population level by favoring certain traits that are passed on through generations. It involves differential reproductive success among individuals with certain traits in response to environmental pressures.
The only traits that can lead to natural selection and evolution are traits that?
increase an organism's chance of survival and reproduction in a specific environment. Traits that are heritable can be passed on to offspring and accumulate in a population over time through the process of natural selection, leading to evolution.
How could an organism end up with those two different beneficial alleles through the process of natural selection and genetic recombination?
An organism can end up with two different beneficial alleles through natural selection and genetic recombination. Natural selection favors traits that increase an organism's chances of survival and reproduction, leading to the spread of beneficial alleles in a population. Genetic recombination, which occurs during sexual reproduction, can shuffle alleles from different parents, creating new combinations of alleles that may be beneficial. Over time, these processes can result in an organism having two different beneficial alleles that enhance its fitness.
What is a population that changes over time due to natural selection?
A population of organisms that changes over time due to natural selection is called a evolving population. Through natural selection, individuals with traits that are better suited to their environment tend to survive and reproduce, leading to changes in the frequency of traits within the population over generations.
What is a requirement for evolutionary changes to occur through natural selection?
A requirement for evolutionary changes to occur through natural selection is the presence of genetic variation within a population. This variation can lead to differences in traits that affect an organism's ability to survive and reproduce. Over time, individuals with advantageous traits are more likely to pass on their genes, causing those traits to become more common in the population.

What statements best describes the relationship between adaptations and natural selection?
Adaptations are traits that enhance an organism's ability to survive and reproduce in its environment. Natural selection is the process through which these advantageous traits become more common in a population over generations, as individuals with beneficial adaptations are more likely to thrive and pass on their genes. Therefore, adaptations are the result of natural selection acting on variations within a population. Together, they drive the evolution of species.

What is a survival gene in evolution?
A survival gene is a gene that increases an organism's ability to survive and reproduce in its environment, leading to its higher prevalence in the population over time through natural selection. These genes are advantageous for the organism's survival and reproduction, ultimately contributing to its evolutionary success.
The development of these adaptations can best be explained by the concept of?
The development of these adaptations can best be explained by the concept of natural selection, where advantageous traits increase an organism's chances of survival and reproduction. Over time, these traits become more common in a population as they are passed down through generations, leading to the evolution of specific adaptations.
What is the source of new traits in a population?
New traits in a population can arise through mutations in the DNA of an organism. Mutations are changes in the genetic code that can result in new characteristics that may be passed on to offspring. These traits can then be subject to natural selection and other evolutionary mechanisms.
Explain how the structure and function of DNA enable species to change over time through natural selection.?
The structure of DNA allows for genetic variation through mutations, which introduce new traits into a population. Natural selection acts on these variations, favoring traits that increase an organism's fitness for its environment. Over time, these advantageous traits can accumulate in a population, leading to species adaptations and evolution.
Is adaptation inheritable?
Adaptations can be heritable if they are encoded in an organism's genes and can be passed on to future generations through reproduction. This process, known as natural selection, allows beneficial adaptations to become more common in a population over time.
Why are vegistal structures not removed by natural selection?
Vestigial structures are not removed by natural selection because they often do not significantly impact an organism's survival or reproductive success. These structures may have lost their original function but can still exist without detrimental effects. Additionally, if a vestigial structure does not impose a substantial cost to the organism, natural selection may not act strongly against it, allowing it to persist through generations.
