Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
That natural selection is a random process.
The question is semantically equivalent to asking 'What are the four parts of the existence of a banana?' I cannot answer it.
the factors that are necessary for natural selection by evolution to occur are: 1)variation in characteristics;different individuals in a population must have different characteristics. 2)differencies in fitness different characteristics of different individuals must contribute to differences and fitness. 3)heritability of characteristics characteristics that affects fitness must be heritable.... example:passed by genes from one generation to the next)
The fossil record is life's evolutionary epic that unfolded over four billion years as environmental conditions and genetic potential interacted in accordance with natural selection. It shows us the changes species have incurred over millions of years.

1. the animals are stupid duhhlol
The four stages are: Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction
Overproduction, genetic variation, selection, and adaption
Overproduction, variation, selection, and adaptation
See the related answer below for an answer to this question.
- natural selection - sexual selection - genetic drift - immigration/emagration
Mutation, Natural Selection, Migration, and Genetic Drift.
overproduction: to many offspring and 3 others
The question is semantically equivalent to asking 'What are the four parts of the existence of a banana?' I cannot answer it.
Natural selection occurs when four conditions are met: 1. There is variation among individuals. 2. That variation is at least partially heritable. 3. That variation is linked to differential reproductive success. 4. More individuals are born than can survive and reproduce.
I doubt it as I just was speaking to he and his wife in Maui at the four Seasons hotel.
Among myriad others; fossil evidence, artificial selection, biogeographic distribution of organisms and molecular genetics.
