Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.

What are 4 main points of the theory of evolution?
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
What are the 4 points of Darwin's theory?
Darwin's process of natural selection has four components.

- Inheritance. Some traits are consistently passed on from parent to offspring. ...
- High rate of population growth. ...
- Differential survival and reproduction.
