Answer 1

means natural selection and speciation leads to evolution........

Answer 2

• Natural selection is defined as the change in frequency of some genes in a population, which gives survival advantage to a species.

• Whereas speciation is the development of a new species from pre-existing ones.

• This leads to a sequence of gradual change in the primitive organisms over million of years, to form newer species which are very different from older ones. This is called evolution.
