Meaning
Variation is the difference between living creatures.
About Variation
- There is variation between different species; different species look different from each other.
- There is variation within a species, creatures of the same species don't look exactly the same as each other.
- Variation is useful to help a species survive. If everyone was the same, what kills one person might kill everyone.
- Variation within a species can be inherited or caused by the environmental. Some people are born with 3 fingers (inherited variation) but others might lose fingers in an accident (environmental variation).
Examples of Inherited Variation
Eye colour varies from person to person. | The pattern on the backs of frogs shows variation. | Variation in patterns on snail shells means some are better camouflaged than others. |
