Environmental pressure. Amongst a certain population of a certain species, there will be many different mutations which developed and were passed on evenly due to neither being beneficial nor detrimental.
Any change to their habitat can be considered an environmental pressure. A drop in temperature, invasion of a competing species, etc. Natural selection will occur, as those with now-beneficial mutations are more likely to pass their genes on.
What else can I help you with?
What is the third step in natural selection?
There are really no steps in natural selection - just conditions required for it to occur.
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.
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 are variations in a species needed for natural selection to occur?
Variations in a species are needed for natural selection to occur because they provide the raw material for evolutionary change. Without variation, there would be no differences for natural selection to act upon, and individuals within a species would be identical. Variations allow some individuals to be better adapted to their environment, giving them a higher chance of survival and reproduction, thus driving the process of natural selection.

How is genetic diversity important to the concept of natural selection?

what causes natural selection to occur?
the presence of predators
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
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
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 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
Is choosing one or none from a box of chocolates natural selection?
Neither artificial or natural selection. Chocolates, even variant chocolates, do not fit the criteria needed for either type of selection. No fidelity or fecundity.
Which tends to occur more quickly natural selection or artificial selection?
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
