Darwin’s evolutionary doctrine is a holistic doctrine of the historical development of the organic world. The essence of evolutionary doctrine lies in the following main points:
1. Organisms are variable – individuals of the same species differ from each other. It is difficult to find a property by which individuals belonging to the same species would be completely identical.
2. Differences between organisms, at least in part, are inherited.
3. Theoretically, plant and animal populations tend to multiply exponentially, and theoretically, any organism can fill the Earth very quickly. But this does not happen, since vital resources are limited, and in the struggle for existence the strongest survive and stubbornly reproduces offspring.
4. As a result of the struggle for existence, natural selection takes place – individuals with properties useful in the given conditions survive. Survivors pass these properties to their offspring, that is, these properties are fixed in a series of subsequent generations
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
