variatio brings about evolutionary change with in species as over millions of years the have to adapt to the ever changing habbitats. take the horse for example millions of years ago it used to have multiple toes.yet over millions of years it has evolved to only have one toe

Which statement best explains the significance of meiosis in the process of evolution within species?
Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
Do variations in populations lead to new species?
Variations in offspring are acted upon by natural selection: some offspring will be slightly more proficient at producing new offspring than others. This means that some alleles will promulgate throughout the population gene pool at a faster rate than others, resulting in a shifting frequency of incidence in the population gene pool. This is what evolution is: shifting allele frequencies in the population gene pool.
How does natural selection lead to evolution (apex)?
small changes add up over time
How does variation lead to natural selection?
If all individuals in a species are not exactly clones of each other but have small variations in the genes (traits), some will do better when the environment changes. These traits will be "favored" over other traits. More individuals will be found with the trait.
Why does a lump of lead have a greater mass than a lump of wood?
The molecules of lead are more massive and are more densely packed together than those of wood.

How does earths tilt on its axis lead to seasonal changes?
Earth's tilting on its axis leads to seasonal changes due variations in the angle (rather than distance) at which light hits.
Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
How can habitat degradation cause changes in an area's biodiversity?
Alterations of a habitat may lead to drastic changes in a ecosystem and may even lead to the extinction of a species.
Which of the following best explains why commodity futures contracts are transferable?
They can be bought and sold but the obligation in the contract remains a valid
Which is the correct order in which brain changes that lead to alcoholism?
Brain changes don't lead to alcoholism. Alcoholism can lead to brain changes.
How will variations in organism be useful in plant and animal breeding?
Variations in organisms can certainly be useful in plant and animal breeding. These variations lead to adaptions to the environment.
What is overproduction?
Overproduction is a driving force in natural selection, as it can lead to adaptation and variations in a species. Darwin argued that all species overproduce, since they have more offspring than can realistically reach reproductive age, based on the resources available. -Google More offspring are produced than can survive. -gradpoint/novanet
5 factors that lead to the formation of a new species?
(i) Absence of gene flow (ii) accumulation of different variations (iii)natural selection (iv) genetic drift (v)reproductive isolation.
How does natural selection lead to evolution (apex)?
