Essay on Darwin's theory of natural selection.
Answers
Answer:
Essay on Darwin's theory of evolution and natural selection.
Explanation:
This paper gives an explanation of Darwin’s theory of natural selection. As well, the paper fully gives a description of natural selection in terms of “modern evolutionary synthesis” of the 20th century. The paper also gives application of the principles of natural selection to explain the current problem of antibiotics resistance in bacteria. Finally the paper gives a summary of scientific theories about evolution before Darwin’s discovery of natural selection.
Generally this is a very important theory which has been greatly adopted by students and teachers of genetics presently.
Darwin’s theory is significantly a very important landmark in the process of evolution and origin of species. The principle is regarded as the key to the formation of new and superior species from old and existing ones. This is to say that nature selects superior traits, which are transmitted to the offspring in a manner that is independent on the other. The major explanation behind the theory is that one superior allele tends to be dominant over the others, blending a genetic make up and traits that influence a certain trait segregate during organism growth and development. Therefore, this research paper looks at all principles of natural selection, its relationship to the current problem of antibiotics resistance in bacteria, and its description in terms of “modern evolutionary synthesis” of the 20th century.
Summary of Scientific Theories about Evolution before Darwin’s Discovery of Natural Selection
Darwin’s theory of Natural Selection is generally regarded as a significant landmark in the origin of organisms and evolution process. Before Darwin, many scientists like him alleged that species evolved from other species or antecedent. Mostly during those times there was no any scientific evidence to prove that concept hence many theories went unnoticed. Prior to Darwin’s theory especially in medieval times, the concept of evolution was not much appreciated for the reason that origin of organisms was regarded as Gods creation. This idea
- Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.
- Natural selection causes evolution, the change in the heritable traits characteristic of a population over generations.
- It is called Darwin's theory of natural selection, discovered by Charles Darwin.
