Natural selection is the result of natural occurrences. In an area that gets a lot of snow, small animals that don't blend in with white snow are more likely to be spotted by predators. Since they would get killed more, they would have less offspring, and the population of that animal would tend towards fur that blends in with white snow. No one reached a hand in to select only white furred animals for breeding, but the effect is the same.
Artificial selection is the result of human interference. In this case, some one would reach a hand in to select certain animals to breed. In a garden of flowers, all different colours would normally grow. If a human cut off all non-white flowers before they pollinated, only white flowers would breed, so the garden would become more and more full of white flowers.

What is the difference between evolution and theories of evolution?
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
How can you use natural selection in a sentence?
Natural selection may ultimately be his downfall.
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 are the 7 types of evidence that supports Evolution by Natural Selection.?
Fossil record showing transitional forms Anatomical homologies between different species Molecular homologies in DNA sequences Biogeographical distribution of species Direct observations of natural selection in action Developmental similarities among different species Vestigial structures in organisms, indicating evolutionary history.
Who proposed th theory of evolution by natural selection?
Charles Darwin proposed the theory of evolution by natural selection in his book "On the Origin of Species" published in 1859. It states that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce.
What is the main similarity between the process if artificial selection and natural selection?
The similarity between artificial and natural selection is that they are both weeding out unfavorable traits for favorable traits to be well equipped for survival.
Does competition occur only between members of the same species?
When competition occurs between species, the stronger species remain. This process is called: natural selection.
What is the name given to the difference in characteristic between organism of the same species?
The difference in characteristics between organisms of the same species is called "genetic variation." This variation can arise from mutations, sexual reproduction, and environmental factors, leading to diversity in traits such as size, color, and behavior within the species. Genetic variation is essential for natural selection and the overall adaptability of populations.
What is the difference between natural and artifical selection?
Natural selection - is allowing the species to breed at their own convenience - with whichever member of the opposite sex they choose. Artificial selection is human intervention in that natural process - allowing breeders to choose the best genes for the species.
Do all species have natural selection?
yes.
What is the formation of new species by natural selection?
We call this speciation, and is largely driven by evolution and natural selection.
How is natural selection used in artificial selection?
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
Who wrote the book The Evolution of the Species by the Means of Natural Selection?
The book "On the Origin of Species by Means of Natural Selection" was written by Charles Darwin.
Natural selection will ultimately make a species?
evolve
How is natural variations used in artificial selection?
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
How natural selection help few species to survive and how few others got extinct?
how natural selection help some species to survive and few got extinct
What is true about nature selection?
Natural selection usually causes a species to change gradually
