What factors support evolution-?
As we currently understand it, evolution happens if: - There are populations of organisms reproducing with variation - Those variations are inherited by offspring - More offspring is produced than can comfortably subsist in the habitat - Offspring therefore compete with one another for resources and mating opportunities - Variant inherited traits affect their ability to compete.
What is heritable variation?
Heritable variation is the variation in characteristics caused by genetic factors.
What is the relationship between evolution and genetics?
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
How does meiosis aid in evolution?
contributes to genetic variation.
The fact that an organism's offspring are not identical is known as?
inherited variation
What is main cause of evolution?
All evolution begins with reproductive variation - the fact that all offspring are born nonidentical to both their parents and their siblings.

What are parts of Darwin's theory of evolution?
living things over produce variation among offspring struggle to survive desirable traits are more fit.

How is variation related to evolution?
The more variation there is in a group of specimens, the more evolution can occur between them.
What are variations the result of?
Healthier offspring with more variation of their genes, which means that there are a wider variety of the differing alleles. Another result is that the offspring may have favourable characteristics (in the case of evolution) and also they could be more adaptable to the environment if it were changing.
What does it mean when Darwin saw that variation exists within a species?
When studying and proving the theory of evolution, Darwin notice that variations existed within species. Species includes organisms that are closely related and can mate to produce fertile offspring. Variation is a difference. Darwin noticed that there were more than one organism inside a species.
What is heritable variation?
Heritable variation is the variation in characteristics caused by genetic factors.
Is the hippo able to pass on variation to offspring?
Yes, any animal that undergoes sexual repoduction can pass on variation to their offspring, provided that variation is contained in the gametes, or germinative cells.
