Answer:
For evolution to happen the main points are as follows:
-High rate of reproduction
- Struggle for existence
- Variation
- Survival of the fittest
- Natural selection
Step-by-step explanation:
The success in survival and reproduction depends upon the characteristic traits of an organism, for example only those rabbits will survive which are fastest. There is struggle for existence and in this there will be survival of the fittest. The phrase survival of fittest was first used by Herbert Spencer. The same context was asserted by Darwin as Natural selection.
