Answer 1

Hint: This theory is related to the survival and reproduction of individuals in certain conditions.

Complete answer:
In 1859, Charles Darwin, a British naturalist proposed the theory of Natural Selection which was based on his most famous work Origin of Species.

Additional information
- Charles Darwin set out his theory of natural selection as an explanation for adaptation and speciation.
- The concept was simple but strong that the individuals best adapted to their environment are more likely to survive and reproduce.
- If the variations occur among the individuals then the one with beneficial variation will be selected by the environment.
- The variations are heritable and it will move on next-generation leading to progressive evolution.
- Darwin’s ideas were inspired by the observations he had made on the second voyage HMS Beagle.
- Darwin defined evolution as “descent with modification“, the idea that species change over time, give rise to new species, and share a common ancestor.
- Darwin proposed natural selection because resources are limited in nature, organisms with favorable heritable traits will produce much better offspring.

Evolution is the change in population and species of organisms over time.

Note: Alfred Russel Wallace was a naturalist who discovered evolution before Darwin. Wallace was afraid to reveal evolutionary beliefs while Darwin published his belief in evolution making him famous and his ideas of natural selection got accepted worldwide.
