What does changing environments do to traits and natural selection?

It can change a lot of things.
Let's say there's an island with white sand and a volcano. On this island there is a species of white lizards, brown lizards, and black lizards. Of course, natural selection will pick of the brown and black lizards because birds can see them more they can the white lizards in the white sand. So, as the brown and black lizards get eaten, over time more and more white lizards shall show up and there will be more white lizards than brown and black lizards.
Now, let's say the volcano erupts and now black ash is all over the white sand, turning it black. The white lizards are now completely exposed. However, the brown and black lizards are seen less. As natural selection picks off the white lizards there will be more and more brown and black lizards. Even though the brown lizards are there they can still be seen a little because they're not black like the ash; but there are still more of them than the white lizards.
All in all, natural selection can raise and lower the amount of traits a population has through the environment.

What are organisms with traits best suited to their environments are most likely to survive?
Natural Selection
What allows organisms to survive the process of natural selection in their environments?
the unequal ability of individuals to survive and reproduce
Is natural selection responsible for inherited traits?
no, inherited traits are responsible for natural selection
What genetic change allows organisms to survive natural selection in their environments analogies acquired traits adaptations learned behaviors?
Adaptations
How do differences between individuals and environments affect natural selection?
Differences between individuals may affect differences in their average reproductive success, causing the variant traits of individuals that have greater reproductive success (fitness) to become more prevalent in a given environment than rival traits. As environments change, so may the traits that have a reproductive advantage change. This is natural selection.
Organisms with traits well-suited to their environments survive and reproduce at a greater rate than less well adapted organisms in the same environment is called?
Natural Selection. Survival of the fittest. The organisms with the best traits are able to survive and reproduce.
Idea that species can gradually adapt to their environment is called idea that species can gradually adapt to their environment is called?
natural selection
What would be the most effective in changing the frequency of certain traits in a population over time?
natural selection. -study island.

Why Over time why does natural selection continue to work?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
