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 else can I help you with?
What are organisms with traits best suited to their environments are most likely to survive?
Natural Selection
What is the Role of fertilization in natural selection?
Fertilization plays a crucial role in natural selection by contributing to genetic variation within a population. When organisms reproduce, genetic material from two parents combines, leading to offspring with diverse traits. This variation is essential for natural selection, as it allows certain traits to be favored in changing environments, enabling species to adapt and survive. Ultimately, the differential survival and reproduction of individuals with advantageous traits drive evolutionary change.
Is necessary for natural selection to act on a population of organisms?
Yes, natural selection is essential for driving evolutionary change within a population of organisms. It acts on heritable traits that affect an organism's survival and reproduction, favoring those individuals with advantageous traits. Over time, this can lead to adaptations and the evolution of new species. Without natural selection, populations may not adapt to changing environments, which can lead to decreased survival rates.
Is natural selection responsible for inherited traits?
no, inherited traits are responsible for 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?
This is known as "natural selection." It is a key mechanism of evolution where organisms with advantageous traits for their environment have a better chance of surviving and passing on those traits to their offspring, leading to the gradual adaptation of populations to their specific environments.
What variable force is most important to adaptation over time?
The variable force that is most important to adaptation over time is natural selection. Natural selection acts on heritable traits within a population, favoring those that provide a survival or reproductive advantage. This process leads to the accumulation of beneficial traits over generations, resulting in adaptation to changing environments.
What allows organisms to survive the process of natural selection in their environments?
the unequal ability of individuals to survive and reproduce
What is another term for natural selction?
Another term for natural selection is "survival of the fittest." This phrase, popularized by Herbert Spencer, emphasizes how individuals with advantageous traits are more likely to survive and reproduce in their environments. Natural selection drives the evolution of species by favoring these traits over generations.
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.
How does evolution by natural selection result in adaptibility?
Evolution by natural selection results in adaptability because individuals with beneficial traits for survival and reproduction are more likely to pass those traits on to their offspring. Over time, these advantageous traits become more common in the population, leading to increased fitness and adaptability in response to changing environments.
What would be most effective in changing the frequency of certain traits in a population over time?
natural selection. -study island.
