What are the 5 main points of Darwin's theory?
The five theories were: (1) evolution as such, (2) common descent, (3) gradualism, (4) multiplication of species, and (5) natural selection.
What are the 5 parts of Darwin's theory of evolution?
In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation.

What are the main points of Darwin's theory of evolution?
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 the five parts of how evolution occurs?
The Process of Natural Selection
- Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. ...
- Inheritance. Some traits are consistently passed on from parent to offspring. ...
- High rate of population growth. ...
- Differential survival and reproduction.
What are the main points of Darwin's theory?
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 the 3 main points of Darwin's theory?
Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.
What are the 4 main points of Darwin's 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 6 main points of Darwin's theory?
Terms in this set (6)
- Overproduction. Most species produce more offspring than can survive.
- Competition. Since living space and food are limited, organisms must compete for the necessities.
- Variation. Differences between individuals in a population.
- Adaptations. ...
- Natural selection. ...
- Speciation.
