Question

Define ‘evolution’. Describe Darwin’s theory of evolutio?

Answer 1

Evolution implies an overall gradual development of the differentiated organisms from the pre-existing less differentiated organisms over the course of time.

Darwin's Theory of Evolution :-

Theory of Evolution by means of natural selection.
Darwin and Wallace proposed that natural selection is the mechanism by which new species arise from pre existing ones. Natural selection states that there is 'struggle for existence' within a population and variation exists within all population. The continues competition between individuals for environmental resources creates a  'struggle for existence' and this struggle makes sure that certain organisms would fail to survive or reproduce. This would eliminate less suited organisms and better adapted organisms would survive and pass on their traits to next generation leading to evolution.
