Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
What is the third step in natural selection?
There are really no steps in natural selection - just conditions required for it to occur.
How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
Why would natural selection not occur in this population?
The population has not yet reached the carrying capacity.-apex :D
Does natural selection occur in the world today?

what causes natural selection to occur?
the presence of predators
What requires natural selection to occur in a population?
genetic variation
Can natural selection occur in an individual organism?
No, its a group thing.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What term is defined as natural change that occur in communities over time?
Natural selection
Natural selection is also known as the survival of the what?
It is also known as Survival of the Fittest.
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.
