Sexual selection is driven by competition for mates and the preferences of individuals for certain traits that increase reproductive success. This can include physical characteristics that indicate good genes or social status, as well as behaviors that demonstrate fitness or compatibility. Ultimately, sexual selection is a mechanism that shapes the evolution of species by influencing which individuals are successful in reproducing.

What are other evolutionary mechanisms besides natural selection?
Other evolutionary mechanisms besides natural selection include genetic drift, gene flow, mutation, and sexual selection. Genetic drift is the random change in allele frequencies in a population. Gene flow refers to the transfer of genes between populations. Mutation introduces new genetic variation, and sexual selection drives evolutionary change through mate choice and competition for mates.
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.
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 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.
What type of selection causes evolution?
Whatever physical attributes are most useful in the current environment. For instance if there was a group of rabbits, the fastest would avoid predators best, if it then mated with another fast rabbit the baby rabbits would all grow up to be faster.
What kind of selections occurs in many birds when males that build strong nests help care for young are chosen by females as mates?
This is called, sexual selection.

Among peacocks the males with the brightest and showiest feathers are favored as mates by peahens what is this example of?
sexual selection
What is the difference between sexual and natural selection?
Natural selection is survival of the fittest, while sexual selection is a preference for a given trait made by the limiting sex. It is strangely, but usually in opposition to natural selection (E.G., male peacock's tail feathers that garner attention from predators and prevent the peacock from fleeing well).

What has the author M B Andersson written?
M. B. Andersson has written: 'Sexual selection' -- subject(s): Sexual selection in animals
Is it true that from birth a child experiences sexual drives?
From birth, children do not experience sexual drives in the way adults do; their sexual development is a complex process that unfolds over time. Infants exhibit behaviors related to attachment, comfort, and exploration, but these are not sexual in nature. Sexual drives begin to emerge during puberty when hormonal changes activate sexual feelings and desires. Prior to that, children's experiences are more focused on emotional and physical needs rather than sexual ones.
How has God made a peacock special?
Natural Selection and Sexual Selection has made a peacock 'special'.
Which condition may result in speciation?
Sexual Selection.
