Fish lay a large number of eggs, few of which are fertilized and very few of which hatch into young ones. Still fewer live to maturity and very few of these are fertile. Which principles of evolution are represented in this example?

A. Descent with modification and evolution
B. Struggle for existence and survival of the fittest
C. Adaptation and artificial selection

Respuesta :

Descent with modification and evolution

Answer:

Option B, Struggle for existence and survival of the fittest

Explanation:

According to the Darwin’s theory of natural selection species which adapts themselves to the changing environmental condition in order to become efficient enough to survive and reproduce are termed as the “fittest” and thus he further stated that it is the “fittest” species which is able to survive.  

Option B also outlines the same concept and thus it is correct choice.
