Why would this form of behavior most likely be naturally selected? Organisms that have behaviors that encourage reproduction would be more likely to reproduce.

What does it mean that traits behaviors are naturally selected?
Natural selection is a process where organisms with beneficial and advantageous traits survive better than others. As generations pass, the species will have many organisms that have that advantageous trait.
What causes natural selections?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
What behaviors does natural selection in general favor?
Natural selection is a process that favors heritable traits that increase the survival chances of an organism, allowing the organism to reproduce more!
What type of selection occurs naturally?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
How does natural selection apply to humans?
One example of recent natural selection in humans involves the ability to tolerate the sugar, lactose, in milk. In most parts of the world, adults are unable to drink milk because their body switches off the intestinal production of lactase, an enzyme that digests the sugar in the milk, after weaning.
What can natural selection act on?
Natural selection acts on the phenotype, the characteristics of the organism which actually interact with the environment, but the genetic (heritable) basis of any phenotype that gives that phenotype a reproductive advantage may become more common in a population. ... Natural selection is a cornerstone of modern biology.
What is natural selection in psychology?
the process by which such forces as competition, disease, and climate tend to eliminate individuals who are less well adapted to a particular environment and favor the survival and reproduction of better adapted individuals, thereby changing the nature of the population over successive generations.
Why does natural selection only act on heritable variation?
Why does natural selection only act on heritable variation quizlet? ... It can only act on heritable traits because organisms that are better suited to survival and reproduction will pass their genes onto the next generation. Only heritable traits, that can be passed on, have any affect on the next generation.
What is natural selection examples?
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.
Why does natural selection in a stable environment favor specialists?
Explanation: In a population, the natural selection will favour the individuals with the higher fitness (In other words : the ones which have the best chances to survive and reproduce) in a given environment. ... It means that, for different environment, one gene can give different trait values at the phenotypic level.
What is required for natural selection?
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
What is the role of natural selection in the development of these traits?
Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Why is natural selection important to humans?
Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. That causes their genes to become more common in the population over time, and it's the way species evolve to adapt to changes in their environment.
How does natural selection relate to genetics?
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
How did natural selection affect human evolution?
The study suggests that positive Darwinian natural selection -- in which some forms of a gene are favored because they increase the probability of survival or reproduction -- is responsible for the increased rate of evolution.
