Species diversify via genetic mutations. Say organism A has 4 offspring, and they all have trait 1, which is characteristic of the species, except one baby, which has trait 2 (call this one organism B). Later on organism B has offspring which all have trait 2, and a couple other new traits that are uncharacteristic of the species. Eventually, the descendants of organism B will be so different from the descendants of organism B's siblings, that they could be considered a new species.

How does genetic variation prevent extinction of a species?
The genetic variation enable a particular species to withstand the adversities of Nature by way of selection on the basis of the principle of survival of the fittest.
Discribe what biodiversity means?
Biodiversity means the degree of variation of life. Some examples would be genetic variation in a species or ecosystem variation in a planet.
How does variation ensure that a species to survive?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
Why is sexual reproduction preferable to a species?
It promotes genetic variation.
Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
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.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
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.
How could you distinguish between a species in which there is a lot of variation and two separate species?
Sometimes it is very hard to distinguish between a species where there is a lot of variation between that of a variation that is actually two separate species. Many times scientist disagree on how to tell these two things apart.
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
How genetic variation is measured?
Gentic variation is mearsured by the number of species in the given area not.
A difference in an inherited trait of an organism that may lead to new species?
variation
Does sexual reproduction cause a narrow range of variation or a wide range of variation in species?
SIM=
Does sexual reproduction cause a narrow range or variation or a wide range of variation in species?
