More offspring are produced than can possibly survive.

|
The organisms that are the fittest are always largest and strongest.
|
|
|
The number of offspring is not related to fitness.
|
|
|
Acquired characteristics that are inherited are the cause of evolution.
|
Detailed explanation-1: -Organisms are capable of producing more offspring than their environments can support. Thus, there is competition for limited resources in each generation. Offspring vary in their heritable traits.
Detailed explanation-2: -More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.
Detailed explanation-3: -Natural selection or survival of the fittest: During the struggle for survival, only those individuals who are more adapted to their surroundings and show favourable variants are selected. Species Origin: According to Darwin, new variations arise in each generation and are passed down to the next.
