Question

What is natural selection? Is it similar to survival of the fittest? How are the 2 alike? How are they different?

Answer 1

Answer:

Difference: Survival for the fittest is the survival of species/organisms with genes better suited to the environment and are selected for survival and passed to the next generation while natural selection works by giving species who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.

Explanation:

Evolution is the slow/gradual development of human beings from simple life forms into higher forms of life over millions of years ago as stated by Charles Darwin in his book 'The Origin of Species' in 1959. He argues that human beings evolved from simple life forms into higher forms of life through:

       1.Mutation - abrupt change in the form of a living organism as dictated by the climate or genetic components of the living thing involved.

       2.Natural selection - a process in which the stronger species out compete the weaker ones for resources (Survival for the fittest).

       3.Environmental adaptation - follows after the first two, where the surviving species isolate themselves from others as they adapt to the new environment.
