What is the starting point for all natural selection?
Mutation and recombination leading to variations in organisms. Without these variations there would be nothing to select from.
How can mutation affect evolution?
Mutation can serve up the raw variation that natural selection selects from, thus alleles are changed over time in populations of organisms; evolution.
What is a mutation and how does it relate to evolution?
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
What are Darwin's two main principles for evolution?
Mutation and Natural Selection
What drives the process of evolution?
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.

What process thought to have changed the genetic code over billion years ago?
Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
Natural selection cannot occur without what?
Variations within a population. Variations mean traits that only certain individuals have that give the individual a greater or lesser chance of reproducing.
What are genetic mutation and natural selection?
Together, genetic mutation and natural selection determine in what 'direction' evolution proceeds.
What two factors are responsible for evolution?
Mutation and natural selection.
Can evolution explained by science?
Evolution, the change in allele frequency over time in a population of organisms, is explained by science. Natural selection, mutation, genetic drift and gene flow explain just about all of the basics of evolution.
Why are mutation and recombination important in the process of natural selection and the evolution of organisms?
When a mutation occurs in the replication process, it changes certain features, like maybe better eyesight, and maybe bigger eyes, or bigger claws, and the meaning of evolution is when something changes into a better form.
What is the relationship between Natural selection and Genetics?
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
