Answer:

Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection

Explanation:

2. Some of these variations are passed on to offspring;

As the genetic changes may occur due to mutations in the genes.
As these changes do not occur in days or months but they occur after hundred and thousands of years.
The off springs are distinct from their ancestors. This results in the formation of new species. Gradual modification of the existing species leading to the formation of new species is known as speciation.

4.Individuals vary in their ability to survive and reproduce;

Those with the most favorable adaptations are more likely to survive and reproduce.
Individual variation (usually through mutation) may introduce traits or abilities that enable that individual to survive in order to reproduce. Usually these are tiny incremental changes that accumulate over centuries or millennia.

Note: However there are certain drawbacks of Darwinism even such as it failed to explain the basis of variation and the mode of transmission of characters.

How did the kingdoms went from 2-6

Makovka662 [10]

Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.
