If you say you have an island inhabited by a species then something like an earth quak happens and the island splits apart and both parts cant see each other or any thing like that you have the species split onto seperate islands there would be different forms of food on them and they would have to adapt to them or maby different land variations like ones island will have bushes and one will have trees the animal could become a girraf as an example to reach the trees or a cow to reach the bushes.

Is it true that through natural selection harmful variations gradually accumulate in a species?
yes
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.
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.
According to the theory of natural selection a species that lacks the variations necessary to adapt to a changing environment will most likely do what?
Go extinct.
What principle states that living things change gradually over time through natural selection?
The theory of evolution by natural selection.
Is it true that through natural selection harmful variations gradually accumulate in a species?
yes
How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
What is another term for natural selections?
Survival of the fittest
What Accumulate mean?
an increase by natural growth or addition
What are the 4 principles of natural selections?
LAWN Light Air Water Nutrients

The graphs of the 3 types of selection and label the average and the extremes?
There are three types of selections. The three types of selections include: disruptive selection, natural selection, and directional selection.
What variations do natural selection depend on?
They depend on natural variation in traits due to mutation.
What is an important factor of natural selection?
Variations within a population
A series of helpful variations in a series results in?
natural selection
Why variations are important in human life?
Variations are the basis of evolution, but variations within a population create diversity, which is useful to slow disease and allow natural selection to occur.
What is the theory stating every organism displays slight variations from other organisms of its kind?
The theory of natural selection states that every organism displays slight variations from other organisms of its kind. It also states that the struggle for limited natural resources results in individuals with certain natural variations adapted to their specific environments.
