What else can I help you with?
In the case of the english peppered moth what best describes the role natural selection played in shaping the phenotype of this species?
Elimination of the phenotypes that were no longer well adapted to the color/shade of the trees these moths rested/gathered on. Thus the variation that was best suited to the new environment was represented better in future populations of this organism. Simply, evolution. *PLATO USERS* I don't have the correct answer, but it is NOT answer "B) Natural selection created the variation within the population, then acted accordingly" Anything to help, update this please!
What did Charles Darwin used the least to support natural selection?
Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
How does the process of natural selection differ from sexual selection in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms that drive evolution, but they differ in how they shape species. Natural selection is based on survival and reproduction, where individuals with advantageous traits are more likely to survive and pass on their genes. Sexual selection, on the other hand, is based on traits that increase an individual's chances of mating, such as elaborate displays or physical characteristics. While natural selection focuses on survival, sexual selection focuses on reproductive success and mate choice.
What is artificial selection in biology and how does it differ from natural selection in shaping the genetic traits of organisms?
Artificial selection in biology is the process by which humans intentionally breed organisms with specific traits to produce offspring with desired characteristics. This differs from natural selection, which is the process by which environmental factors determine which traits are advantageous for survival and reproduction in a given population. While natural selection occurs in nature without human intervention, artificial selection is driven by human choices and preferences.
How does sexual selection differ from natural selection in shaping the evolution of species?
Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
How do natural selection and sexual selection differ in their roles in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
How is natural selection important to biomes?
Natural selection plays a key role in shaping the characteristics of organisms within biomes. It helps organisms adapt to their environments over time by favoring traits that increase their chances of survival and reproduction. This process contributes to the diversity and equilibrium of species within a biome.
What is the relationship between natural selection and phylogenty?
Natural selection is the process by which certain heritable traits in a population are favored, leading to their increased frequency in future generations. Phylogeny, on the other hand, is the evolutionary history and relationships among organisms. Natural selection plays a key role in shaping the characteristics of species over time, influencing their phylogenetic relationships as some traits become more prevalent in descendant species.
How is natural selection important?
Natural selection is important because it is the process by which species adapt to their environment over time, leading to the survival of the fittest individuals with advantageous traits. It plays a key role in shaping and driving evolution by enabling organisms to become better suited to their ecological niche, ultimately increasing their chances of survival and reproduction.
Explain how natural selection is important to bio-mes and organisms?
Natural selection is a key mechanism of evolution that drives the adaptation of organisms to their environments, shaping the biodiversity within biomes. By favoring individuals with advantageous traits that enhance survival and reproduction, natural selection enables species to thrive under specific ecological conditions. This process not only influences the characteristics of organisms but also impacts the dynamics and stability of entire ecosystems, as species interact with one another and their environment. Ultimately, natural selection helps maintain the balance of life across various biomes.
Explain the difference between artificial and natural selection?
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
What is natural selection and how does it play a role in shaping the evolution of species in biology?
Natural selection is a process in biology where organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. Over time, this leads to the evolution of species as those with beneficial traits become more common in a population.
