Name and define the five distinct ideas in Darwin’s theory of evolution by natural selection.
I need two more theses are the ones I have:
Populations show variation for almost all traits.
Certain variations improve survivorship and the number of offspring left (improve fitness) If these variations are heritable, their frequency increases each generation.
Are theses even right?
Since this is not my area of expertise, I searched Google under the key words "Darwin 'natural selection'" to get these possible sources:

I hope this helps. Thanks for asking.
Yes, your two ideas are correct, but there are three more distinct ideas in Darwin's theory of evolution by natural selection. Here are the five ideas:
1. Variation: Within a population, there is variation in the traits of individuals. This means that individuals within a species are not identical but have different characteristics.
2. Overproduction: Populations have the potential to produce more offspring than the environment can support. This leads to competition among individuals for limited resources.
3. Adaptation: Certain individual variations are better suited to the environment and provide a higher chance of survival and reproduction. These advantageous traits are known as adaptations.
4. Natural selection: The environment acts as a selective pressure, favoring individuals with beneficial adaptations. These individuals are more likely to survive, reproduce, and pass on their favorable traits to the next generation.
5. Evolution: Over time, as advantageous traits are passed on from one generation to the next, the frequency of these traits within the population increases. This leads to evolutionary change, as populations become better adapted to their environment.
