How do helpful variation accumulate in a species over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.
How helpful variations accumulate in a specie over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.
What may a series of helpful variation in a species result in?
Adaptation
How do helpful variations accumulate in species over time?
They don't die as often (or as fast) as the "non-helpful" variants.
What are specific examples of variation within a species?
Human species, as in the variation in height.
What is a major cause of variation within species?
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
What is a variation that can help an organism survive?
A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs. If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring. Slowly variations accumulate and one species changes into a new species - this is called evolution.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.
What is variation among members of the same species called?
Intraspecific variation
Why is variation good for a species?
Sometimes positive variation can improve some ability of the species adapted to the environment. For example, a kind of virus can be killed by medicine A. A small part of the virus has some variation that make it can be alive with medicine A. The species of the virus can exist in future, or it will disappear in the future in the environment full of medicine A. Besides, positive variation can provide some capacity for the species to get more resource in the competition. Of course, there is negative variation that might contribute to the disappearance for the species. That is just another side of variation.
