===Meaning===
'''Variation''' is the difference between [[organism]]s in an [[ecosystem]].
: There is [[variation]] within a [[species]], [[organism]]s of the same [[species]] don't look exactly the same as each other.
: [[Variation]] can be [[Continuous Variation|continuous]] or it can be [[Discontinuous Variation|discontinuous]].
: [[Variation]] within a [[species]] is the result of both [[genetic]] and environmental factors.
: The greater the [[genetic]] [[variation]] within a [[species]] the more likely a [[species]] will survive changes in the environment. Individuals may die, but with enough [[variation]] some of them will be better [[Adaptation|adapted]] to the change in their environment.
===Genetic Variation===
: Most of the [[variation]] between different [[species]] can be accounted for by the [[DNA]] differences between those [[species]].
: The [[Variationvariation]] within a [[species]] is the result of both due to [[geneticmutation]] and environmental factors.The greater the s causing different [[geneticphenotype]] s. These [[variation]] within a s caused by [[speciesmutation|genetic mutations]] are the more likely a source of [[Evolution by Natural Selection|evolution]]. ===References=======AQA==== :[specieshttps://www.amazon.co.uk/gp/product/1782945598/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945598&linkCode=as2&tag=nrjc-21&linkId=ad276ad49df77ab4b40ab4fd0fe10395 ''Variation, page 73, GCSE Combined Science; The Revision Guide, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1782945563/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945563&linkCode=as2&tag=nrjc-21&linkId=9a1d023a374038e6072f33c4f3cf808b ''Variation, page 95, GCSE Biology; The Revision Guide, CGP, AQA ''] will survive changes in the environment:[https://www.amazon.co.uk/gp/product/0198359373/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359373&linkCode=as2&tag=nrjc-21&linkId=952a73bbb09d222ecc4b50d200679849 ''Variation, pages 199, 208-213, 218-234, 236-241, GCSE Biology; Third Edition, Oxford University Press, AQA '']:[https://www.amazon.co.
