∙ 12y agoNatural selection is when an organsim develops a new trait to help it survive. An animal could become more marine if it needed too, by eventually evolving into having fins. This is how many species were created. This new trait could be an advantage, causing the organism to be able to live longer/reproduce more, and eventually become more common. This often happens when an organism needs to adapt, so it gradually evolves to fit its surroundings--that's survival of the fittest.
I'm in 7th grade Biology right now, and we learned this in March. Hope I helped!:)

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.
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
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.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
What is the relationship between evolution and natural selection?
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Is natural cause the same as natural selection?
No, they are two different things.
Is adaptation a cause of natural selection?
No, it's exactly the other way around: natural selection causes adaptation.
Which mechanism of evolution can cause adaptation?
Natural selection.
What can cause natural selection to go faster?
mutation
Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
What are the advantages and disadvantages of natural selection to an organism?
Natural selection can help creatures adapt to their enviorment. Sometimes this can cause unwanted problems.
What is the name of the process that cause a species to evolve?
natural selection
Can RNA undergo a natural selection and cause evolution or change?
no
How are intelligent design and natural selection alike?
They aren't. Intelligent design posits that natural selection cannot create life as we know it, and inserts a deity as the cause.
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.
